Passive margins are also of paramount economic importance in terms of hydrocarbon resources. This interdisciplinary session seeks contributions from geological and geophysical observations, as well as from geodynamic or geomaterials modeling, addressing the interplay of deep mantle - lithosphere - basin - surface ? climate and erosion processes in passive margin systems and adjacent continents. We solicit thermochronological studies contributing to onshore ? offshore feed-back processes, studies related to magmatic activities in passive margins, seismic studies of the lithosphere and mantle, basin modeling, as well as geodynamic modeling related in particular to mantle dynamics and its multiple surface expressions. Emphasis is given to the North and South Atlantic system and adjacent continents but the session welcomes contributions on other passive continental margins as well. The session addresses the many complex interacting feedback cycles that acted since the breakup of continents. We also encourage scientists concerned with the long-term evolution of fracture zones at passive continental margins and adjacent continents to present their data. *Convener: Ulrich Anton Glasmacher * Co-Conveners: Hans-Peter Bunge , Peter Japsen , Delphine Rouby , Francois Guillocheau , G.

Invited presentation: Thomas Funck (GEUS, Denmark) Abstract: Our understanding of the geologic evolution of the Arctic Ocean and surrounding landmasses remains fragmentary. Over the past decade, a wealth of new data have been acquired and combined with legacy data collections to generate new ideas and models concerning the tectonic and oceanographic development of the Arctic. Such models are increasingly transcending Paleozoic to present-day timescales, sedimentary through to deepest mantle domains, as well as onshore to offshore environments. The Arctic is a region of diverse and multi-phase plate tectonic motions - both vertical and horizontal. Its present configuration is largely considered the result of a dominantly extensional regime, with a protracted period of North Atlantic rifting and far-field plate stresses having also affected the region. Several compressional events, such as the Eurekan, Ellesmerian, Caledonian, Timanian orogenies, as well as neighbouring subduction and terrane accretion from the Pacific, have also influenced the Arctic. Widespread rift and mantle plume-related magmatism have occurred and offer key constraints on the timing of tectonic events, and the interaction of surface and mantle processes - but relationships have not yet been fully exploited and synthesized. Furthermore, the nature and age of key bathymetric features, and the timing for the opening and closing of oceanographic gateways, remains uncertain. The next generation of circum-Arctic geodynamic models must incorporate constraints from various sub-disciplines. These geologic and tectonic models are required to understand the oceanographic development of the Arctic and how it interacted with the rest of the world's oceans. We envisage a highly interdisciplinary session with a focus on: (1) Constraints on the age, structure, and geography of the Arctic, including the fossil, sedimentary, crustal, lithospheric and mantle records. (2) Integrative tectonic models and geodynamic processes and, (3) Insights on how the tectonic development of the Arctic affected oceanographic processes and exchanges with the other oceans.

Please note the abstract submission deadline of 11 January 2017. Hope to see you there! GD7.2/EMRP4.9/SM10.2*Anisotropy from crust to core: Observations, models and implications* Many regions of the Earth, from crust to core, exhibit anisotropic fabrics which can reveal much about geodynamic processes in the subsurface. These fabrics can exist at a variety of scales, from crystallographic orientations to regional structure alignments. In the past few decades, a tremendous body of multidisciplinary research has been dedicated to characterizing anisotropy in the solid Earth and understanding its geodynamical implications. This has included work in fields such as: (1) geophysics, to make in situ observations and construct models of anisotropic properties at a range of depths; (2) mineral physics, to explain the cause of some of these observations; and (3) numerical modelling, to relate the inferred fabrics to regional stress and flow regimes and, thus, geodynamic processes in the Earth. The study of anisotropy in the Solid Earth encompasses topics so diverse that it often appears fragmented according to regions of interest, e.g., the upper or lower crust, oceanic lithosphere, continental lithosphere, cratons, subduction zones, D'', or the inner core. The aim of this session is to bring together scientists working on different aspects of anisotropy to provide a comprehensive overview of the field. We encourage contributions from all disciplines of the earth sciences (including mineral physics, seismology, magnetotellurics, geodynamic modelling) focused on anisotropy at all scales and depths within the Earth.

These geodynamically important developments stem from interpretations of forward or inverse modelling of primary observations, such as seismograms, magnetic anomalies, fission track picks and so on. Proper cross-disciplinary use of these results therefore requires a clear understanding of the assumptions and limitations that underlie these raw observations, as well as the resulting modelling and interpretation. Geodynamic modelling has likewise seen significant progress as manifested in the improved ability to predict synthetic seismic waveforms for mantle structures derived from forward modelling and to retrodict past mantle flow using inverse methods. Thus the potential exists to evaluate various geophysical observations within the context of the known physics of mantle convection. Our goal is to significantly improve the understanding of the deep Earth and its interaction with shallow processes, making the most of this serendipitous confluence of theoretical advances and the wide range of often complementary observations. This session aims at gathering scientists working across disciplines to link geodynamic observations and predictions from seismology, mineral physics, basin analysis, seismic stratigraphy, fission track analysis, geomorphology, geochemistry, and plate motion modelling. -------------------- Co-conveners: Lorenzo Colli, Siavash Ghelichkhan, Bernhard Schuberth (LMU Munich) Mark Hoggard (Cambridge) Giampiero Iaffaldano (Copenhagen) Nathan Simmons (LLNL) Abstrtact deadline: 11th January 2017 (13:00 CET) We look forward seeing you in Vienna.

Ritske S. Huismans, Guillaume Duclaux, Delphine Rouby, Magdalena Scheck-Wenderoth Session description The formation of rifted continental margins by extension of continental lithosphere leading to seafloor spreading is a complex and still poorly understood component of the plate tectonic cycle. New observations and modelling allow us to investigate the underlying processes. Key questions that need to be resolved include 1) factors that control the geometry and crustal architecture or rifted margins, 2) the role of strain localisation and strain partitioning throughout the rift history, 3) factors controlling the 3-dimensional geometry of rifts and passive margins, 4) processes responsible for anomalous vertical motions during basin evolution such as phase changes or small scale convective instability of the mantle lithosphere, 5) fundamental controls on the magmatic or a-magmatic nature of rifts and passive margins, 6) interaction between surface processes, tectonics, and climate during rift-passive margin evolution. We encourage abstracts that offer new insights into crustal and lithospheric architecture and processes underlying rifting and passive margin formation as well as smaller scale studies of individual sedimentary basins, using constraints from observations and modelling. ------------------------------------------- Professor Ritske S.
