100 years past Wegener: Plate tectonics, meteorite impacts, climatic evolution and sedimentation
A1 Subduction Processes and Continental Collission (O. Oncken, T. John, G. Franz)
A1-01 Monitoring Plate Boundary Systems and Observing Megathrust Earthquakes
Bernd Schurr, Frederic Tilmann, Andreas Rietbrock (GFZ Potsdam, GFZ Potsdam, Uni Liverpool)
The last decade has seen a surge of giant subduction earthquakes with the events in Sumatra (2004), Chile (2010) and Japan (2011) among the largest ever observed. This activity fell into a time when new space based observational techniques matured and dense modern seismic and geodetic networks were put in place, providing unprecedentedly rich data on the megathrust seismic cycle. The many surprising aspects revealed by these data demonstrate that long-term monitoring of the subduction system is key to improve our understanding of megathrust behaviour and mechanics. In this session we invite contributions from seismology, geodesy, remote sensing, geology, rock deformation and other observational fields presenting new observations and interpretations of newly collected data. We specifically encourage reports on instrumentation deployed for the observation of subduction zones, e.g. creepmeters, tiltmeters, seafloor geodesy and multi-array installations. We interpret plate boundary systems in a wide way and therefore explicitly also encourage submissions related to processes or earthquakes in the outer rise, upper plate and downgoing slab.

From Geodetic Imaging of Seismic and Aseismic Fault Slip to Dynamic Modeling of the Seismic Cycle
A1-02 Fluids in subduction zones – from a deformation to geochemistry perspective
Ilona van Dinther, Matthias Konrad-Schmolke; Matthias Rosenau (ETH Zürich, Uni Potsdam, GFZ Potsdam)
The liberation, migration and interaction of fluids in subduction zones has important geodynamic and geochemical implications. These range from short-term seismic pumping to long-term water recycling into the deeper mantle and calcalkaline magmatism. Fluids may play diverse roles in this context both in a mechanistic sense, e.g. as lubricants, as well as in a geochemical sense, i.e. as element carrier. To map the effects of fluids in its various roles and at various scales in subduction zones, field and experimental observations as well as models from various geoscientific fields will have to be unified into a cross-disciplinary framework. With the intention to trigger discussions towards such a unified framework, we invite contributions from geochemistry, mineralogy, rock mechanics, seismology, geodynamics, volcanology and tectonics.
A1-03 From oceanic subduction to continental collision: a metamorphic and magmatic geochemical perspective
Chistoph Beier (Uni Erlangen, Uni Potsdam), Ralf Halama (Keele University, UK)
Convergent margins represent major geochemical pathways for the material exchange between the Earth’s surface and the deep mantle. One of the fundamental issues is the extent to which elements are returned to the surface, stored in the mantle wedge or recycled back into the mantle. During subduction, volatile and fluid-mobile elements are released from the subducted slab by metamorphic reactions, which exert a fundamental influence on the Earth’s volatile cycling. Moreover, the released elements impact the geochemical characteristics of magmas that are produced above subduction zones. In addition, the depletion of the mantle wedge prior to arc-related melting is evident from a depletion of the high field strength elements. When subduction leads to continental collision, evidence of prior subduction can still be found in the metamorphic rock record and in the geochemistry of collision-related magmatic rocks.
This session focuses on the petrology and quantification of chemical and isotopic compositions of subduction zone inputs, the progressive metamorphic processing of slab materials, and the general characteristics of melts generated in convergent margin settings. These data provide direct constraints on key aspects of arc magmatism, generation of continental crust and deep mantle refertilization, in both modern and ancient arcs. We solicit contributions from field-based and experimental geochemistry and petrology, to expand our knowledge on the origin and evolution of arcs from the early initiation through the mature arc stages towards continental collision. We also welcome contributions from oceanic and continental backarc spreading centres.
A1-04 Mountain building on the scale of grains and atoms
Claudia Trepmann, Uwe Altenberger, Rainer Abart (LMU München, Uni Potsdam, Uni Wien)
The mechanics and kinematics of mountain building processes are intimately linked to mechanical, thermal and chemical transformation processes on the scale of grains and atoms such as crystal-plastic processes, grain-boundary migration, crystallization and recrystallization, mineral reactions, and dissolution-precipitation in the presence of fluid or melt. The transformations proceed in response to a multitude of driving forces. The resulting micromechanisms critically react to transient conditions and disequilibrium situations may be imprinted in the rock’s microfabrics, including structural, crystallographical, mineralogical, and chemical patterns. Microfabrics are the key to understanding the mechanisms of transformation ultimately underlying mountain building processes and to extract rate and process information.
We aim to bring together researchers working on all kinds of microfabrics to shed light on the interactions between micro-scale and orogen-scale processes, mechanical and chemical transformations, mineral reactions, and associated microfabric evolution. We invite submissions focused on any material relevant to Earth; from laboratory, field, analytical and numerical perspectives.
Session keynote (proposed):

Preliminary lecture title: Microfabrics of mineral host-inclusion systems: constraining formation mechanisms and tectonometamorphic evolution
A1-05 Motion and time in orogenesis
Johannes Glodny, Axel Gerdes, Armin Zeh (GFZ Potsdam, Uni Frankfurt, Uni Frankfurt)
Understanding motions of the Earth requires the exact knowledge of the timing of processes that caused the formation and transformation of the Earth’s crust and mantle. This session welcomes all kind of contributions, which present new geochronological data derived by different techniques from crust and mantle rocks, and provide new constraints on the timescales and processes which shaped the Earth from the Hadean until present day. Contributions dealing with the development of new and innovative geochronological methods are welcomed as well.
A1-06 Subduction systems – missing link between Wegener´s concept of continental drift and plate tectonics
Jan H. Behrmann, Michael Stipp, both at GEOMAR, Kiel
The existence of subduction and collision zones was not adequately accounted for by Alfred Wegener´s ideas of continental drift. This was mainly due to the absence of observations on the structure, kinematics and dynamics of active continental margins, and has greatly hampered acceptance of his theory. In this session we welcome contributions reporting new work on subduction systems, especially their initiation, the forces driving subduction, mass balance, and the rheological evolution and dynamics of subduction and collision zones.
A2 Rifting/ Continental Breakup/ MORB/ Transform Faults (M. Scheck-Wenderoth, M. Weber)
A2-01 Plate tectonics, plate boundary deformation and intraplate tectonics: Observations and models on global, regional and basin scale
Dietmar Müller, Sascha Brune, Christian Heine, Mark Handy (Sydney University, GFZ Potsdam, Shell Intl. Expl. & Prod., The Hague, FU Berlin); Anke Friedrich, Uni München; David Hindle, Uni Göttingen
This session focusses on advances in amalgamating regional and global data sets for plate tectonic and “deep-time” plate deformation models. The goal is to provide new insight into the driving forces of plate motion and deformation. We invite contributions that explore links between plate-scale tectonic processes and the spatio-temporal patterns of deformation, erosion and deposition recorded in sedimentary basins and mountain belts. Individual topics include the interplay between plate kinematics and mantle motion leading to orogenesis, basin formation and -reactivation at continental margins and interiors; forward modelling of lithospheric deformation processes; linking regional-scale models to geological observations through new data and computational infrastructure; and multi-disciplinary approaches to forge links between lithospheric deformation and mantle convection processes.
The notion that lithospheric plates are rigid is fundamental to plate tectonic theory. Nevertheless, numerous geodetic and geological observations show that plate interiors are subject to deformation over a range of scales. Slow vertical and horizontal motion associated with intraplate deformation raises important issues both for understanding lithospheric rheology and tectonics and assessing the resulting earthquake hazards. Recent progress in the field of intraplate tectonics is based on acquisition of new high-resolution geological, geochemical, and geophysical data, as well as on reanalysis of the classic ideas and data on intraplate tectonics, which may have been under-appreciated in the wake of plate tectonic interpretations in recent decades. Examples include the active intraplate deformation of midcontinental North America and Australia as well as the Mesozoic tectonics of Central Europe.
This session aims to explore the characteristics and kinematics of deformation in plate interiors, drawing on a wide range of examples world-wide, both from the present and the geological past. We invite contributions from observational, experimental, theoretical and numerical modelling studies of deformation of the lithospheric-plate interiors.

Mantle temperature and the time scale of extensional basin subsidence
A2-02 Continental breakup and passive margin evolution
Peter Kukla, Sebastian Kollenz, Ulli Glasmacher (RWTH Aachen, Uni Heidelberg, Uni Heidelberg)
The separation of lithospheric plates represents the initial stage of the Wilson Cycle and is still one of the most enigmatic processes in plate tectonics. It features multiple phases of volcanism, rock and surface uplift and subsidence - not only recorded during initial rifting and breakup but as more and more evidence indicates long after breakup in the Passive Continental Margin (PCM) stage. PCMs therefore store the long-term and large-scale evolution of Earth processes related to mantle and lithospheric dynamics, the break-up of continents, the evolution of sedimentary basins, the long-term landscape, changes in ocean circulation patterns and their effect on climate. Research concerned with continental breakup and passive margin evolution is therefore potentially interdisciplinary reaching from field based studies to analogue and numerical modeling of deep mantle processes and linking to surface-climate-erosion processes.
For this session we consequently seek contributions that contribute to elucidating the feed-back processes between deep and shallow earth processes. We envisage a wide range of contributions that offer new insights into lithospheric processes underlying rifting and passive margin formation, fundamental controls on the magmatic nature of passive margins, post breakup modifications and recent structure and physical properties of passive continental margins and adjacent continents. The offshore crustal, volcanic and sedimentary architecture of rifted margins, and the associated onshore connection will be a further focus. Contributions from worldwide examples and from a broad range of disciplines are welcome.

A2-03 Large Igneous Provinces: relation to continental breakup
Eleonora Rivalta, Guillaume Jacques, Gabriele Uenzelmann-Neben, Robert Trumbull (GFZ, Geomar, AWI, GFZ)
This session aims to explore progress in understanding the controls of magma generation and transport in Large Igneous Provinces with or without a link to continental breakup. The interplay of tectonic and magmatic processes in these settings presents many unsolved problems. Important aspects to be discussed include melt generation and crust-mantle interaction, the development and evolution of magma reservoirs, magma transport in dyke and/or sill complexes, and the formation of volcanic rifted margins.
Contributions are welcome that present new insights from studies of key regions such as the South Atlantic, especially those that showcase advances by combining field and/or laboratory observations in petrology, geophysics, geochronology and tectonics with geodynamic modelling of LIPs. Questions to be addressed include but are not restricted to: What is the causal link between LIPs and plate tectonics? How are LIPs formed? Have most oceanic LIPs formed at triple junctions? Do submarine LIPs have a similar ore potential as continental LIPs? Why have so many of these events taken place in the Cretaceous (150-50 Ma)?
A2-04 Intraplate volcanism in the oceanic and continental environment
Oliver Nebel, Christoph Beier, Lothar Viereck, Michael Abratis, Jörg Büchner (ANU Canberra, GeoZentrum Nordbayern, Uni Jena, Uni Jena, Görlitz)
Intraplate magmatism is the energetic expression of a dynamically active Earth. It is that type of magmatism that provides the most profound insight into the heterogeneity of the mantle. Magmatic processes forming oceanic islands or continental volcanic fields are initiated either directly by physical (e.g. thermal) or compositional (e.g. mineralogical) deviations in the mantle or by external tectonic forces due to interaction of lithospheric plates. As probes of the heterogeneous Earth's interior, the composition of melts allows constraints on mantle sources as well as crustal and lithospheric recycling. The compositional variations and physical properties of minerals, gases and their host melts serve as monitors of solids and melts from mantle through the crust to eruption. Magmatic processes in anorogenic continental interiors are often associated with the initiation of continental separation, but may have other causative mechanisms. In particular understanding the nature of the underlying mantle source and its relation to the LAB (lithosphere-asthenosphere-boundary) may hold the key to understand magmatism in anorogenic volcanic fields.
For this session, we aim to bring together experts in the broad field of oceanic and continental intraplate magmatism investigating the multifarious aspects of igneous systems. We invite contributions from the fields of geochemistry, petrology and geophysics to address open questions related to driving forces of igneous melt generation and the role of the LAB, to mantle sources, modes of mantle melting, causes for ascent, stagnation, crystallization, degassing of melts and their interaction with the lithosphere as well as studies focusing on the evolution of volcanic fields. We particularly encourage contributions from early career scientists. Depending on their number and quality the contributions of this session may be published in a special issue of the Journal of Mineralogy and Geochemistry (Neues Jahrbuch für Mineralogie).
A3 Planetary Plate Tectonics and Impact Cratering Studies (T. Spohn, A. Airo, U. Reimold, D. Breuer)
A3-01 Meteorites and Early Planetary Evolution
Harry Becker, Ansgar Greshake, Thomas Kruijer, Vera Laurenz (FU Berlin, Museum für Naturkunde Berlin, Uni Münster, Uni Bayreuth)
We invite contributions that address the early history of meteorites, asteroids and the terrestrial planets, including studies of early differentiation processes that may have set the conditions for their subsequent geodynamic evolution.
A3-02 Impact Cratering in the Planetary System
Kai Wünnemann, Christopher Hamann (Museum für Naturkunde Berlin)
The collision of cosmic bodies has been, and still is, one of the most fundamental processes in the evolution of planetary surfaces. The scales of relevant processes range from the microscale (e.g., shock wave modifications in minerals) to the mesoscale (e.g., deformation and melting of rocks) to the macroscale (e.g., crater formation) and, ultimately, to a planetary-wide scale (e.g., environmental/biological effects). “Terrestrial impact structures are more abundant, larger, older, more geologically complex, more economically important, and even more biologically significant than anyone would have predicted a few decades ago” (Bevan French, one of the pioneers in this field of research). The multidisciplinary character of impact research combines methods of various disciplines, including remote sensing, field observations, laboratory experiments, and numerical modeling. Accordingly, we invite contributions from (1) Experimental impact cratering and numerical modeling of crater formation, (2) Shock-metamorphic effects in rocks and minerals, (3) Remote sensing of impact craters on Earth and other planetary bodies, and (4) Field studies on terrestrial craters and new crater discoveries.
A3-03 Earthlike Planets: Plate tectonics vs stagnant lid tectonics
Doris Breuer, Tilman Spohn (DLR)
Contrary to Earth with its plate tectonics, the other earthlike planets and moons in the solar system feature stagnant lids on top of their convecting interiors. Unfortunately, it is not well understood why the tectonic style of the Earth is so different but it is generally assumed that the presence of water on the Earth’s surface and in its interior may play an important role. Water - as is well known - has substantial effects on the rheology of rock making near surface crustal rock more susceptible to (plastic) deformation and reducing the viscosity of the mantle. In addition, planetary size, core size, surface temperature and the concentration of heat producing elements have also been proposed to help determine the tectonic behavior of a planet. Plate tectonics is recognized as being an indispensable element of the chemical cycles that run between the atmosphere, hydrosphere, and the interior stabilizing the climate and the habitability of the planet. It is being speculated that life may itself have a stabilizing effect on the chemical cycles, the water budget and ultimately on plate tectonics. We invite contributions on the differences between and the controlling mechanisms of the tectonic modes, on why the Earth is unique and on the consequences for the thermo-chemical evolution of a planet and its habitability. Contributions that go beyond the solar system and consider rocky exoplanets are very welcome.

Plate Tectonics on Earth and on rocky exoplanets – Novel Insights into Mantle Dynamics
A4 Mantle Circulation/ Driving Forces (S. Sobolev, H. Marquardt)
A4-01 Mantle flow: geophysical imaging and large-scale geodynamic modelling
Bernhard Steinberger,Nicola Tosi, Claudio Faccenna (GFZ Potsdam, DLR Berlin, Uni Roma Tre); Christine Thomas, Andy Nowacki (Uni Münster, University of Bristol)
Flow in the Earth mantle provides an important driving force for plate motions and deformation, and has an important influence on how the lithosphere is modified throughout Earth history. Modeling of mantle flow is challenging because of uncertainties in rheology, which is probably complicated, and in density anomalies due to both temperature and compositional variations. There are numerous observational constraints, but they are often not straightforward to interpret. Here we invite all contributions to study mantle flow, in particular on large scales -- both regarding what flow structures and implied mantle mixing are possible for various sets of parameters and assumptions, and regarding the actual flow globally or in certain regions, as inferred from models constrained by observations. Also, contributions describing new observational constraints to large-scale flow are encouraged.
The Earth's mantle is convecting on many length scales from small-scale convection in layers to whole mantle flow. Large mantle flow such as subduction processes and plumes create anomalies in mineralogy and temperature and those might be visible using geophysical imaging techniques. Especially seismology has the advantage of illuminating deep mantle regions through reflected, refracted and scattered waves and tomography has given impressive images of mantle flow. Here we invite contributions from all fields of geophysics but with a focus on seismological imaging of mantle flow.

A4-03 Properties of Earth Materials and Constraints on Mantle Flow
Hauke Marquardt, Robert Farla, Patrick Cordier (Uni Bayreuth, Uni Bayreuth, Université Lille 1)
Heat flow in Earth’s mantle enables viscous flow of mantle material over long time scales and drives plate tectonic convection. Volcanism, and the continuous creation and subduction of oceanic lithosphere regulate the exchange rates of energy and material between the Earth’s interior and surface/atmosphere. Geophysical observations provide increasingly detailed constraints on flow patterns in the mantle. For instance, seismic anisotropy in tectonically active regions in the mantle, such as spreading zones or boundary regions, is most likely related to preferred alignment of crystallites caused by the prevalent tectonic stress. Furthermore, tomographic images of fast and slow seismic wave speeds in the mantle are often associated with descending slabs and ascending plumes. This interpretation, however, remains ambiguous as varying wavespeeds could be caused by factors such as anomalous temperatures, partial melting, deformation associated with high dislocation density, or the presence of water. A detailed interpretation of these large-scale geophysical observations in terms of mantle flow patterns therefore should be synergized with information about the physical and chemical properties, and behaviour of Earth’s materials under high temperature and pressure conditions in the laboratory or in computer simulations. In this session, we welcome contributions on the properties of mantle materials that relate to our understanding of material flow in the mantle.

A4-04 When and How did Plate Tectonics Begin on Earth
Robert Stern, Taras Gerya, Stephan Sobolev (Univ. Texas Dallas, USA; ETH Zürich; GFZ Potsdam)
Wegner's argument for continental drift started the avalanche of geoscientific advances that led to the theory of Plate Tectonics, which is the unifying paradigm for how the solid Earth convects and cools today. Unresolved is the issue of when in Earth history Plate Tectonics began, and how the transition from preceding stagnant/deformable lid tectonics occurred. In this session we will explore the related topics of when, why and how Plate Tectonics began on Earth. A wide range of studies are invited, including geodynamic explorations and models; field studies; geochemical and isotopic studies; comparative planetology; and discussions of what happened before Plate Tectonics; and why it is important for our understanding of the Earth to answer these questions.

A4-05 Archean environments and ecosystems
Alessandro Airo, Christoph Heubeck (FU Berlin)
The Archaean surface provided a very different framework for the nascent biosphere, affected by vigorous tectonic, volcanic and other nonuniformitarian processes. Similar settings may have existed or still exist on other planets. This session will cover all aspects of the early evolution of planet Earth, in particular those emphasizing the growing interconnectedness between geo-, atmo-, hydro- and biosphere.

A5 Evolution – Diversity as a Result of Plate Tectonics (J. Müller)
A5-01 Palaeoenvironmental, sedimentological and biogeographic consequences of the formation and breakup of supercontinents
Johannes Müller, Robert Bussert (Museum für Naturkunde Berlin, TU Berlin)
The episodic formation and breakup of supercontinents, such as Gondwana, is now understood as a key control of Earth’s climatic, biological and biogeochemical evolution. Recognition of this linkage has enabled a novel understanding of sea-level change, global sedimentation patterns, biogeochemical cycles and biological evolution during Earth’s history. Supercontinent assembly eventually led to supermountains, intensified continental weathering, high sediment and nutrient fluxes to the oceans, and has also been hypothesized to increase biodiversity. During breakup of supercontinents, volcanic emissions related to superplumes might have caused mass extinctions and oceanic anoxia. However, most of these relationships are poorly understood, and whether individual events or evolutionary stages are directly linked to supercontinent assembly and breakup remains to be tested.
We invite contributions that discuss consequences of the supercontinent cycle primarily from a sedimentological, palaeontological, and geochemical perspective.
A5-02 Major environmental changes in Earth history: short- and long-term trends
Christoph Korte, Dieter Korn, Clemens V. Ullmann (University of Copenhagen, Museum für Naturkunde Berlin, Uni Exeter)
Earth’s surface environment has been subject to gradual changes, controlled by tectonic and biological processes. It is marked by a number of relatively short-lived intervals of catastrophic environmental change, leading to major perturbations in geochemical cycles and severe biological crises.
In recent years, the refinement of analytical techniques, improved understanding of proxy records, high-resolution (chemo)stratigraphical work and the extension of astrochronology back into deep time unraveled patterns of global environmental change in unprecedented detail.
This session seeks contributions advancing the knowledge about environments and biogeochemical cycles in the past, by way of sedimentological, palaeontological, geochemical and numerical techniques.

A6-01 Tectonic and climatic imprints on the evolution of landscapes
Taylor Schildgen (1), Miriam Dühnforth (2), Bodo Bookhagen (1), Cornelia Spiegel (3), ((1) Uni Potsdam, (2) LMU München, (3) Uni Bremen
Quantifying how tectonics, climate, and erosion shape the Earth’s surface, and any potential feedbacks among the different components in tectonically active settings, is of primary importance to understanding the long-term evolution of landscapes. While the imprint of changes in tectonic forcing has long been recognized in landscapes, understanding how changes in climate affect the system largely remains an open and debated question, particularly when considering that forcing may occur over different timescales. This session aims to present innovative studies that quantify changes in relief, altitude, and erosion over different temporal and spatial scales, particularly those that provide insights into distinguishing the roles of climate and tectonics on landscape evolution.

The production, erosion, and transport of sediments across the Earth’s surface takes place over a range of temporal and spatial scales, entailing the physical and chemical breakdown of rock on hillslopes, sediment mobilization through surface processes, and eventual deposition. In tectonically active mountain belts, sediments are either transported toward foreland basins and beyond or they are stored in intermontane basins. Despite the fundamental importance of a process-based understanding for interpretations of stratigraphic records, it is often challenging to quantify the relative importance of a range of different processes that are active in a landscape. In this session, we examine both the processes that create and transport sediment as well as the rich stratigraphic records that can be used to reconstruct tectonic and climatic forcing over time. We welcome contributions that integrate observations on different spatio-temporal scales, from field-based geomorphic and sedimentary analyses, geochronology and thermochronology, to numerical and physical modeling.

A6-04 Weathering and Global Biogeochemical Cycles – Crossing the Scales
Julien Bouchez, Cornelius Fischer, Jens Hartman, F.v. Blanckenburg (IPGP Paris, Marum, Uni Hamburg, GFZ)
Rock weathering is a key component of the global geological system, involving climate change, the dynamics of continental surfaces, and the evolution of Life. Weathering consumes atmospheric CO2 and stabilizes the Earth temperature, partitions chemical elements between water and secondary products making up soils and river sediments, and releases essential nutrients from rocks to watersheds.
Plate tectonics and continental drift influence weathering processes at all scales. The latitudinal position of continents sets the prevailing temperature, water fluid flow, and production of organic acids via primary productivity.
All these factors will in turn influence the kinetics of solid dissolution and formation at the mineral scale. Such extrinsic factors interact with the intrinsic variability of mineral surface reactivity. Thus, a crucial coupling exists in-between rate variability at the pore scale and below, and the large-scale weathering processes, at basin scale and above.
At a larger scale, plate tectonics will drive mountain build-up and erosion, along with the formation of large floodplain systems, which will exert a major control on the rates and regimes of weathering.
In this session we invite contributions reporting on novel developments in the field of weathering, and especially those discussing the role of plate tectonics on weathering processes and rates. Studies bridging temporal (from the nanosecond to billions of years) and spatial (from the nanometer to the size of our planet) scales are mostly welcome.

A6-05 Quaternary Environmental Changes and Sediment Dynamics
M. Böse, Frank Preusser (new DEUQUA president), (FU Berlin, Uni Freiburg)
Continental drift initiated the basic shape of Earth during the Late Cenozoic and established most of the present sediment routing systems – from High Mountains to the Oceans. During the Quaternary, natural variations in climate and environmental conditions forced sedimentary systems repeatedly to adjust and the dynamics of natural systems are of interest in the context of future global change. While our knowledge of environmental change and sediment system dynamics has during the past decades significantly improved, mainly through advancements of dating methods, there are still important gaps in the understanding of erosional and depositional processes at local, regional and global scales. This session invites presentations on the above mentioned topics, in particular those focusing on the interaction of environmental change and the dynamics of sedimentary systems using interdisciplinary approaches.

A6-07 Glacial tectonics: from push moraines to glacial isostatic adjustment
Christian Brandes, Uni Hannover; Christian Hübscher, CEN Uni Hamburg
The processes and products of glacial tectonic deformation were analysed over one century, but have provoked considerable attention in the community particularly from the mid-1980s onwards. Hence, descriptions are now available on both sub-glacial and pro-glacial styles of deformation. Special emphasis was placed on the understanding of the formation of pro-glacial push moraines, since criteria for their recognition enables accurate delineation of paleo-ice sheet grounding lines. Nowadays, geophysical methods allow analyzing the complex internal geometry of glacial tectonic complexes even in offshore areas and provide new insights into upper-crust deformation and neotectonics. In the last two decades, tectonic processes related to glacial isostatic adjustment (GIA) including the interaction between ice load and salt tectonics moved into the research focus and provide the potential to connect deep crustal processes and surface processes. Especially post-glacial faulting was recognized as an important process that has a distinct hazard potential. We welcome field, modelling and geophysical studies to cover the wide field of glacial tectonics and GIA related tectonic deformation.
A7 Earth Materials in Geological Processes (M. Wilke)
A7-01 Geomaterials as indicators for Earth's light element cycles
Bernd Wunder, Eleanor Berryman, Klaus-Dieter Grevel, Andreas Ertl (GFZ Potsdam, TU Berlin, Uni Jena, Uni Wien)
Light elements (B, Li, N, etc.) and their isotopes are widely used as tracers of geochemical processes. These include weathering, magma differentiation, biogeochemical cycling, metasomatism, ore-body formation, etc. Applications can range from understanding the behaviour of light elements and isotopes in minerals, such as tourmaline, mica, and serpentine, during hydrothermal alteration, subduction of oceanic lithosphere to identifying processes leading to heterogeneities in the mantle and to the reconstruction of former and characterisation of actual environments.
This session aims to bring together an interdisciplinary scientific community of experimental, petrological and computational studies and welcomes submissions covering a broad range of mineralogy- and geochemistry-related topics.

A7-02 Structure, dynamics and properties of silicate melts and magmas
Marcus Nowak; Kai-Uwe Hess (Uni Tübingen, LMU München); keynote: Ilya Veksler (GFZ Potsdam)
The eruptive behavior and compositional variations of volcanic systems is defined by the physical and chemical properties of their feeding magmas. Recently a much deeper understanding of the structure, dynamics and properties of molten silicate (and analogue) magmas (melts coexisting with fluids and crystals) have been developed within the geoscientific community. The purpose of this session is to describe the current state of experimental and computer simulation techniques for exploring the dynamic processes which occur at high temperature and to consider the relationships between melt structure, thermodynamic properties and rheology within these liquids. These fundamental relations serve to bridge the extrapolation from often highly simplified melt compositions studied in the laboratory to the multicomponent and multiphase systems found in nature.

B > CONSEQUENCES FOR MANKIND – AUSWIRKUNGEN AUF DEN MENSCHEN – 100 years past Wegener: Consequences for mankind
B1 Conventional and Non-Conventional Energy Resources (B. Horsfield, W. Dominik)
B1-01 Multi-scale evolution of sedimentary basins
Rolando diPrimio (Lundin Norway AS), Johannes Wendebourg (Total S.A.)
Sedimentary basins are the natural powerhouses from which we draw most of our energy and raw materials, including groundwater, geothermal energy, and fossil fuels. These basins are highly dynamic in a geological sense. Understanding the workings of sedimentary basins in time and space is prerequisite when it comes to resource evaluation, and this means reconstructing the chemical, physical and biological processes, acting sequentially and in parallel. This session offers the opportunity to present and discuss ideas and results drawn from the examination of sedimentary basins at different scales, from nanometres up to hundreds of kilometres. The results of laboratory experimentation and simulation, regional analysis, and numerical simulations are all welcome additions to this session.
B1-02 Rock and Fluids Properties and Interactions in Hydrocarbon Systems
W. van Berk, H.M. Schulz (TU Clausthal, GFZ Potsdam)
You can't tell the vintage of the wine by the shape of the bottle in which it is contained. And so it is with fluids in hydrocarbon systems - rock architecture governs the volume of an accumulation, and pore throats dictate in part how prolific a reservoir is likely to be, but the fluids are often and rather surprisingly understudied. The evolution of pore fluids - be they hydrophobic or hydrophilic - and the roles played by biological as well as physicochemical factors in governing composition and occurrence are open in this session for discussion. Industry and academic minds all welcome!

B1-03 Shales and Coals: Source and reservoir for oil and gas
Ralf Littke, Volker Wrede, M. Kosinowski (RWTH Aachen, Geologischer Dienst NRW, BGR)
Shales have emerged as a real game changer when it comes to global energy supply. Beginning with the Barnett Shale, and rapidly expanding to almost every sedimentary basin in the USA with even a hint of petroleum potential, these inherently tight lithologies (marls, claystones, limestones are all bundled together here) are being stimulated by hydraulic fracturing to release their hidden potential. Other countries have followed suit, albeit very slowly in Europe, because of public debate concerning environmental impact. The measure of success in the USA can be gauged by the glut of gas on the market and the collapse of the gas price in the lower 48. Petroleum liquids are now the main target in the USA, Canada, Argentina and China, amongst others. This session will bring together industry and academia to discuss the factors controlling hydrocarbons in place, and the effectiveness with which they can be released. Contributions concerning how shale gas exploitation impinges upon potable drinking water resources would be welcomed.
B1-04 Exploration and development of natural resource projects
Bernd Teigler, B. Stribrny (DMT, Biodiversity and Climate Research Centre, Frankfurt)
Rapidly growing earth population and the evolving industrialization of developing countries lead to an increasing demand of natural resources. Natural resource projects are the fundamental tool for the discovery and the development of new deposits in order to satisfy increasing demands. This session focuses on the exploration and development of natural resources like hard coal, lignite and peat as well as metallic and non metallic mineral deposits. Even though the different types of natural resources show specific characteristics some common strategies for exploration and development are obvious.
This session offers the chance to present results of successful exploration and development projects and to discuss new ideas and concepts for upcoming challenges in the field of raw materials. Language: English & German / Englisch & Deutsch
B2 Mineral Resources and their Useage (R. Milke, L. Hecht)
B2-01 Marine ore deposits
U. Schwarz-Schampera, T. Kuhn, M. Hannington, S. Petersen (BGR Hannover, Geomar Kiel)
Demand for raw materials has surged in the last decade, requiring the rapid discovery and development of new resources. The supplies of a number of metals have been identified by governments and industry as particularly vulnerable, and Western economies are increasingly dependent on imports for these so-called “critical metals”. Many now consider that deep-sea mining will allow access to new deposits and alleviate supply concerns for some metals. A major question is the extent to which these mineral resources could contribute to needed metal supply. The main interests in deep-sea mining are three classes of mineral deposits: manganese nodules, Co-rich ferromanganese crusts, and seafloor massive sulfide deposits. They occur in all of the world’s oceans, but they are not evenly distributed; their occurrence is controlled by major geological and oceanographic domains. In partnership with the Strategy Group on Mineral Resources of KDM (Konsortium Deutsche Meeresforschung), this session will examine important controls on the location, abundance and characteristics of marine mineral deposits in a range of different settings.
B2-02 Terrestial ore deposits
Albert Gilg, Volker Steinbach (TU München, BGR Hannover)
This session covers all genetic aspects of terrestrial mineral resources. It is aimed at innovative studies on magmatic, metamorphic, diagenetic, hydrothermal and sedimentary/supergene processes within and on the continental crust that lead to economic enrichments in metals, industrial minerals and gemstones. The presentations should include aspects of or-forming processes from ore petrology, geochemistry as well as radiogenic and stable isotope investigations. We also invite contributions to new developments in the field of mineralogical and geochemical exploration methods.

B2-03 Scenarios for the Raw Material Supply of the Far Future
Friedrich-Wilhelm Wellmer, Wolfgang Jacoby, Martin Schoell (TU Berlin, Uni Mainz)
Exploitation of natural resources for food, energy and manufacturing materials is essential for a growing population on this earth that is estimated to be 10 billion in 100 years. Where will we find those resources, can they be exploited without ruining the planet? We invite for this session contributions on (1) Demand and supply of mineral resources for metals and energy, (2) Scenarios for the future of oil and gas use and transition to alternative energy sources and impact on global warming, (3) The oceans as mineral and energy resources, (4) Renewable resources for energy and manufacturing, (5) Social and economic impact on societies, (6) Economic scenarios on demand and supply, and (7) Where will we be in 100 years?
B3 Risks (Tsunami, Earthquakes, Landslides) (G. Dresen)
B3-01 Operational Earthquake Forecasting, Early Warning and Real-Time Risk Reduction
Jochen Zschau; Stefan Wiemer (GFZ Potsdam, ETH Zürich)
Earthquake risk is on the rise, and a substantial proportion of the world’s population is still highly vulnerable to earthquakes. Important preventive actions such as earthquake-resistant construction and retrofitting of structures have not been applied sufficiently to reduce seismic risk on a global scale. Their sufficient application is still hindered by risk governance problems as well as the rapidness of the world`s population increase and people`s growing concentration in large urban agglomerations. In this situation, operational earthquake forecasting (OEF), earthquake early warning (EEW) and real-time actions with focus on reducing the vulnerability of populations and infrastructures (RTA), gain in importance. Recent developments in the respective research field suggest that these have become promising and viable contributions to earthquake risk reduction, in addition to, and together with, the existing ones. The objective of the session is to demonstrate the recent developments and state of the art in operational earthquake forecasting, seismic early warning and real-time risk reduction, including the aspect of real-time vulnerability assessment. The session also asks for innovative and outstanding case studies that show existing and potential practical applications of the scientific results in these fields. Presentations of strategic applications of the OEF, EEW and RTA tools to the protection of populations, structures and critical infrastructures like lifelines and transportation systems, industrial and public critical facilities and power plants among others are specifically welcome. Session contributions may also address the impact of false alarms as well as the problem of uncertain information and its communication to the end-user.
B3-03 Geological signatures of extreme events
H. Bahlburg, M. Spiske (Münster, Münster/Trier)
We seek contributions analyzing the geological, geomorphological, geomechanical and sedimentological processes involved in the generation and preservation of the sediments and sedimentary rocks deposited during plate-tectonically or climatically triggered extreme, catastrophic geological events, modern and ancient. Such events include, but are not restricted to, earthquakes, tsunami, floods, storms and hurricanes, submarine and subaerial mass wasting, and pyroclastic processes. Observations on event magnitudes, rates of change and recurrence intervals relevant for hazard estimates are particularly welcome. Contributions may represent case studies of modern or ancient examples as well as theoretical, analogue and numerical considerations.

Managing the risk from natural perils
B4-01 Topography, Climate and Human Habitat
Diego Rybski, J. Kropp (PIK)
Humankind has been transforming its environment since millennia. Nowadays human interference is visible on both, planetary and regional scales. However, the concrete interactions and constraining boundaries for human activities in particular on regional scales are not obvious. For example, is it possible that mankind alters regional environmental conditions on a level that future subsistence is no longer possible? Are these boundaries extendable and would this cause or would such attempts affect other neighbouring societies? What is the influence of humans on local climate? Is it possible that human activities can also increase geo-risks or influence natural hazards and their patterns? Understanding these processes is mandatory to understand local risks and for safeguarding human habitats.
The development of urban centers is associated with large scale production, extraction of resources from the environment, aggregation of physical infrastructure, land use changes and increased mobility. They are also centers of human welfare, innovation and over-proportional incomes. Cities as highly dynamic entities alter “geospheres” including land and climate, e.g. their exchange of materials with the surrounding environment is often deemed incompatible with sustainability targets. While destroyed ecosystems, disruptions of the local water balance induced by sealed surfaces and or urban water management are visible and perceivable, other like greenhouse gas emissions are not. However, although urban land cover is still quite less, urban centers are not singularities. But how large urban centers influence their surrounding geo-bio sphere is still unknown yet systematic approaches tackling these topics are still in its infancy. The session aims to discuss systematic approaches which may identify urban footprints and the dynamics of exploitation and transforming processes in order to move forward from understanding mechanisms to sustainable exploitation strategies.

B4-03 Transforming the Geo-Biosphere by Humanity: Agriculture and Water Management
Bruno Merz, (GFZ Potsdam, Germany), Günter Blöschl (TU Vienna, Austria)
Geomorphological characteristics on land are diverse and continually changing. They result from processes originating deep in the Earth's interior, but are subsequently transformed directly or indirectly through interference with human activities. The two most pronounced anthropogenic transformative factors on the Earth surface are agriculture and water management. Both factors have tremendously transformed the Earth surface, causing, for instance, changing water, sediment and nutrient balances, or loss and pollution of natural habitat. The session will discuss the magnitude and key mechanisms of the various transformations of the Earth surface inflicted by agriculture and water management. Of particular interest are contributions which focus on assigning causality: How can we unravel the complex relations between drivers and resulting changes? What are promising methodological avenues for attributing Earth surface changes to their driving forces given various process interactions and a multitude of human interventions?

B5 Utilisation of the Subsurface (A. Liebscher)
B5-01 Numerical Simulation for geological underground utilization : Linking geological information to process modelling
Mauro Cacace, Michael Kühn, Florian Wellmann (GFZ Potsdam, GFZ Potsdam, RWTH Aachen)
Understanding of processes in the geological underground is of utmost importance for exploration and exploitation of geo-resources in a sustainable way. Indeed, a quantitative assessment of underground utilization depends largely on the application of numerical simulations of subsurface processes. This requires collaborative efforts from different scientific and engineering disciplines, most importantly, the integration of geoscientific data and knowledge with thermo-hydro-mechanical-chemical process simulations. For this session, we invite contributions that address all these aspects. Contributions might encompass: (1) implementation of static geological/structural models, (2) determination of the relevant model scales depending on the simulated scenarios, (3) model and parameter upscaling and coupling techniques for multi-phase flow problems related to thermal processes, geochemistry and geomechanics, (4) development and/or employment of (semi-) analytical and numerical modelling tools, (5) methods for risk assessment, (6) tools for operational support and (7) benchmarks of models against operational site data and laboratory data.

B5-02 Subsurface storage: Geological information and geochemical processes
Christian Müller, Christian Ostertag-Henning (BGR); Axel Liebscher, Volkmar Bräuer (GFZ Potsdam, BGR); Guido Blöcher, Simona Regenspurg, Stefan Kranz (GFZ Potsdam), Frank Schilling (KIT)
The subsurface in Germany is used for storage of fluids in depleted hydrocarbon reservoirs, salt caverns and aquifers since decades. In recent years, technologies to mitigate climate change are considering the subsurface as a storage space, too. Especially CO2 capture and storage, and energy storage as e.g. H2 and compressed air produced from renewables are placing new demands on subsurface utilization. Hence, also potential conflicts of use as well as potential risks to humans and the environment require detailed consideration.
The session will bring together scientists presenting new findings related to: (1) three-dimensional modelling of the geologic subsurface including the identification and characterization of structural features and the assessment and quantification of storage potentials in porous rocks and salt formations both on basin and regional scale, (2) geochemical processes important for operation of storage sites for e.g. H2 or CO2 and with respect to selection criteria of target lithologies for subsurface storage sites.
Disposal in deep geological formations is the only internationally recognised long-term solution for dealing with higher activity radioactive waste safely and securely and to ensure its long-term isolation from the biosphere to protect man and environment. Geological disposal of radioactive waste requires an interdisciplinary approach covering amongst others geo-scientific and geotechnical issues, civil engineering, material sciences, legal questions and also societal aspects. This session invites contributions that cover all relevant fields for geological disposal of radioactive waste. Contributions may address - but are not limited to - (i) disposal concepts, (ii) fluid-rock interactions, (iii) geomechanics, rheology and petrophysical properties of rocks and engineered barriers, (iv) site characterization, selection and exploration, (v) monitoring technologies, (vi) coupled HTMC modelling, (vii) long-term safety and risk assessment, and (viii) societal aspects.
An ATES system consists typically of a well doublet, drilled into two aquifers that are hydraulically separated by a geological formation of low permeability. Since the production and injection of heat or cold occurs simultaneously, the ATES system is hydraulically balanced. During operation, the conditions (e.g. temperature, pressure) of the storage medium (water) change thus affecting the aquifer properties e.g. by dissolution or precipitation of minerals that influence fluid flow and transport processes. This session seeks results from field or laboratory experiments and/or numeric simulations that characterize and quantify the relevant processes and suggest optimisation methods for ATES systems. Contributions may relate to (1) quantification of relevant processes in ATES systems like convection, conduction, geochemical processes, reactive transport, and micro-biological activities; (2) new exploitation concepts of urban ATES systems like single well or multi well concept or lateral usage of a single aquifer; (3) experiences from operating ATES systems.

B6-01 Cements, Ceramics and glasses
B. Meng, H. Behrens (BAM Berlin, LU Hannover)
Cements, ceramics and glasses are primary materials for modern technology and construction issues. A large variability in composition and microstructure enables adjusting specific properties for practical purposes. GeoSciences contribute specific expertise to many fields of production and application. This session invites abstracts that address such topics, ranging from fundamental to applied research in cements, ceramics and glass industry and technology. Topics could cover microscopic to macroscopic chemical and physical properties in generic earth and material science and especially the methodology establishing the relationships between synthesis, processing microstructure and properties of the materials. We seek contributions from a broad range of fields, including but not limited to laboratory experiments, field observations, industrial research and computer simulations.

B6-02 Archaeometry, monument conservation and dimension stones
Klaus Bente (Uni Leipzig), Christoph Berthold (Uni Tübingen), Angela Ehling (BGR), Klaus Poschlod (LfU Bayern)
Archaeometry is now a well-established field between science and the humanities. Among others, many mineralogical and geochemical methods are used for studies of all kinds of archaeological materials. Especially the variety and complexity of archaeological predominantly inorganic artifacts induce the necessity of a broad range of analytical tools to answer archaeological questions concerning material identification, manufacturing processes, provenance, geochemical settings, dating and authentication.
Dimension stones and other geogenic building materials have been closely linked to the development of human society for several thousand years. In many regions they characterize architecture and landscape, and therefore influence the cultural and archaeological heritage to a large extent. In order to meet the requirements of the modern building industry and also ensure the conservation of lithic cultural heritage, geoscientific knowledge and methods are essential. For this session we invite contributions from the whole field of archaeometry and monument conservation as well as recent findings of investigations referring to dimension stones; their exploration, assessment, exploitation, processing, application and conservation are all part of this.
Also, contributions regarding the application of non-destructive and mobile field analytical techniques are welcome.
B6-03 Energy, materials, and minerals for technical applications
Susan Schorr (Helmholtz-Zentrum Berlin für Materialien und Energie), Christiane Stephan (FU Berlin); Herbert Pöllmann (MLU Halle); Stefan Stöber, Melanie Keuper (MLU Halle, Uni Tübingen)
One of the biggest challenges facing us now and in the future is energy – how to provide it in a way that is secure, affordable, and environmentally friendly and how to ensure that we use it efficiently. To answer these questions, we need integrated research that explores all secure and environmentally friendly sources of energy, investigates all relevant conversion, distribution, storage, and usage technologies, and takes into account the complex system context and the social issues involved.
The session will cover the materials research aspects of energy relevant materials for both, conventional and renewable energy sources. Various kinds of materials, from natural to synthetic/tailored, and their structure-function relationships will be in the focus of the session.
Layered double hydroxides (LDHs), commonly termed as metal-metal-hydroxysalts and anionic clays, are a large group of natural and synthetic minerals containing of different chemical and structural alternating layers. Positive charged brucite-like main layers are separated by interlayer space occupied by reversibly exchangeable anions, additional cations and water molecules. The general chemical structure of LDHs can be represented by the formula [Me2+1-xMe3+x(OH)2]x+[Ar-x/r • nH2O]x- with Me as metal cation and A as anion. Due to the ability of permanent anion exchange capacity LDHs are important for a wide field of applications such as reservoir mineral, catalysis, anion exchanger and absorber. Particularly, different Calcium Aluminates Hydrates play an important role in the hydration process of cements.
In this session scientists are invited to present, analyse and discuss new scientific results.
New and innovative materials have gained a lot of attention in recent years, both for biomedical as well as technical applications. In this session, established and ‘next-step’- Materials for such applications or innovative solutions to solve old problems can be demonstrated. We would like to invite contributions on new materials as well as new developments in analytical methods used for the characterization and investigation of new materials and their properties. We are convinced that the diversity of contribution topics will highlight the potential of high quality research in new materials research and development.
C > ADDITIONAL THEMES
C1 Advances in material characterisation and analytical geochemistry
Christoph Berthold, Jörg Göttlicher (Uni Tübingen, KIT Karlsruhe); Axel Gerdes, Geerke Floor (Uni Frankfurt, GFZ Potsdam)
The session will cover the ongoing developments in materials characterization from both, the chemical and structural point of view. Complementary analysis with combined methods to gain simultaneous insights into structural and chemical properties of various kinds of materials, from geological to technical nature will be one focus. Also, the current progress in improving and optimizing local resolution, detection limits, and measurement times as well as extending measurements conditions to low and high temperatures, pressure or different atmospheres will be another topic in this session. Contributions are welcome that report on instrumental innovations and/or data processing in laboratories, field environment (mobile devices), or in large scale facilities like synchrotron or neutron radiation sources for material characterization.
Our understanding of the Earth's system is based on geochemical data, and as such on the performance of analytical methodologies. New analytical possibilities changed and expanded the view on geochemical processes. Moreover, the quality of the measurements controls the reliability of the interpretations. In this session we invite contributions focusing on the analytical methodologies; new developments, new approaches and applications within (isotope) geochemistry.

C3 Earth Science Informatics for a Dynamic Planet
Robert Huber (Marum), Roland Bertelmann (GFZ)
Research in the past two decades has provided science with an unprecedented wealth of data. The ubiquity of information technology and the rapid growth of the internet have created and unprecedented potential for gaining additional knowledge beyond the initial interpretation of data by aggregating and analysing data from many sources.
Earth and environmental sciences are particularly rich in data coming from heterogeneous sources including loosely networked remote sensor and field observations, laboratory data, as well as simulation and modelling results, which are required to explore the deep time and inaccessible spaces relevant to most geoscience investigations. Technological progress and the emergence of the internet over the past 20 years make this wealth of information and data accessible for rich and comprehensive synthesis to gain new insights into complex processes of the geosphere and its interaction with other systems.
This session discusses the contributions of modelling, GIS and geoinformatics to improve our understanding of Earth as a dynamic planet and how data driven research adds new perspectives in a world rich in data.

This session invites young scientists to present their completed or ongoing research work, i.e. results of their master or PhD thesis. All topics with a sedimentological focus are welcome. The session will continue the tradition of the SEDIMENT meetings to stimulate the exchange of ideas and experiences among German-speaking groups of sedimentologists. Presentations can be given either in German or in English. The most innovative and inspiring oral and poster contribution will be awarded with prices sponsored by the IAS.
C5 Probing and Monitoring the Earth by Scientific Drilling
Ursula Röhl, Michael Stipp, Ulrich Harms (MARUM, Geomar, GFZ Potsdam)
The understanding of key processes of planet Earth including ocean-floor formation and subduction, continental drift and orogenesis, the global climate system and the biosphere is critically built on results from scientific drilling. Increasingly both international and multidisciplinary approaches are required in scientific drilling to address crucial research fields such as climate and environmental variability, natural hazards, resources, deep biosphere and other topics of socio-economic relevance. The primary objective of this session will be to present the accomplishments of scientific results in ocean, continental and polar drilling as well as to identify new developments leading to future scientific achievements.

C6 3D geology and geoinformation – modelling, data storage and distribution
Rouwen Lehné, HLUG Wiesbaden, TU Darmstadt; Helmut Schaeben, TU Freiberg
In the past 20 years geological 3D modelling developed rapidly from a niche existence into a common approach to work. While content related methodological and conceptual questions/issues have been in the foreground in the past, nowadays other challenges complement the range of topics to be considered in the process. How can 3D data be stored the best way? How reliable is modelled content? How can 3D data be provided barrier-free (e.g. regarding the language, data models, etc.) to a maximum of users? What are the web-visualization possibilities? How can outcomes be implemented into downstream work (e.g. groundwater modelling). Just to name a few.
This session, which is supported by the section Geoinformatics of the DGG, invites presenters (users and developers) who are utilizing/developing computer based geoinformation systems and 3D-techniques to visualize, analyze, evaluate and/or distribute geology.

Faszination Alfred Wegener: Leben, Aktivitäten und wissenschaftliche Leistungen
Warum fasziniert uns Alfred Wegener heute noch immer?
Alfred Wegener (geboren 1.11.1880 in Berlin; gestorben im November 1930 in Grönland) war ein deutscher Meteorologe, Polar- und Geowissenschaftler. Als einer seiner wichtigsten Forschungsergebnisse gilt seine erst posthum anerkannte Theorie der Kontinentalverschiebung. Diese hat die wesentlichen Grundlagen zu den Vorstellungen der Plattentektonik revolutioniert. Zu seinen Lebzeiten war Wegener vor allem für seine neuen Erkenntnisse in der Meteorologie und als Pionier der Polarforschung anerkannt. Seine wissenschaftlichen Visionen sind heute noch ein Vorbild für nachhaltige naturwissenschaftliche Forschung. Mit diesem Symposium würdigen wir einen unvergesslichen Geowissenschaftler.
