This session if focussed on unravelling the role that these fundamental geodynamical processes play in modulating Earth's geochemical cycles, atmospheric and ocean chemistry and climate. Questions that might be addressed include: What causes major perturbations in the equilibrium between tectonic plate motion and the ductile deep interior of the planet? How is the periodic amalgamation of continental lithosphere to form supercontinents related to mantle convection patterns? Is there a ?supercontinent cycle? or is there merely a continuum of progressive processes involving many successive collisions and breakup events, without all continental lithosphere ever being assembled into one continent? How can we assimilate clues from the basin sedimentary record, from rift, subduction, and intraplate volcanism into plate-mantle models? How is the punctuated evolution of the plate-mantle system related to geochemical cycles and to surface environmental crises? For this session we welcome abstracts on any aspect of the nature and evolution of tectonic plates and the plate-mantle system, as well as their connection to the evolution of the Earth?s crust and its surface. We also invite contributions on using geophysical and geological observations to constrain plate-mantle interaction through time, including intraplate volcanism. GD2.2/GM4.8/TS9.10 Move-On: ?Models and Observations of Vertical Material Flow influencing the asthenosphere and lithosphere? https://protect-au.mimecast.com/s/-xpDCnxyErCW4qoVTJFZqs?domain=meetingorganizer.copernicus.org Conveners: Ulrich Anton Glasmacher, Hans-Peter Bunge, Anke Friedrich, Barbara Romanowicz Since the 1960?s, one commonly accepts plate tectonics as an expression of the earth's convecting mantle, yet numerous geological features in continental interiors and at some plate margins remained unexplained. The plume-driven vertical material flow in the non-lithospheric mantle serves as a physical model to explain such features (uplifting domes, flood basalts, dike swarms, narrow grabens, broad rifting, etc.) independently of, but in addition to the plate-mode. The general aim of the session is to present and discuss the state-of-the art of the plume mode of mantle convection, its influence on the dynamics of the asthenosphere and the lithosphere, as well as its expression at the earth?s surface. For this interdisciplinary session, we seek contributions from natural case studies (tectonic evolution-sedimentology-thermochronology-geophysics-seismology-palaeoclimate) and from geo-dynamic or geomaterials-oriented (analog and numerical) modeling, which address the interplay of deep mantle ? asthenosphere ? lithosphere ? basin ? surface processes in all plate environments. We will greatly appreciate all geoscientific studies that contribute to the feedback processes causing the evolution of dynamic topography. TS6.4/GD5.7/GMPV7.26/SM1.25/SSP3.30 Breaking and moving plates apart: linking plate kinematics to lithospheric processes and paleogeography https://protect-au.mimecast.com/s/2pXACoVzGQiwALzmsVbxXG?domain=meetingorganizer.copernicus.org Conveners: Gianluca Frasca, Christopher Jackson , Marta P?rez-Gussiny? , Joanne Whittaker, Simon Williams What controls lithosphere evolution during extension? Is lithosphere extension linked to palaeo-oceanography and biogeochemical cycles? The aim of this session is to investigate diverging systems over a wide range of spatial and temporal scales, and at all stages in the life cycle of divergent plate boundaries including continental rifting, mantle exhumation and seafloor spreading. A special emphasis will be given to (1) studies that couple lithospheric deformation models to plate kinematics, and that integrate possibly the role of serpentinisation and/or magmatism in the models. (2) paleogeographic reconstructions revealing the influence of sedimentation and lithosphere structure evolution on biogeochemical cycles and oceanographic circulation at regional and global scales. (3) contributions that elucidate extensional modes through the interplay between tectonic structures, magmatism and the stratigraphic record using field, petrological and seismic data and that aim at a better understanding of distinctive plate kinematic settings. TS6.5/GD5.8/GMPV7.9 Volcanic versus non-volcanic rifts and passive margins, from rift to ridge https://protect-au.mimecast.com/s/KBbfCp8AJQtwgN8ZsGajQV?domain=meetingorganizer.copernicus.org Convener: Ritske S. Huismans, Romain Beucher , Sara Moron-Pollanco , Delphine Rouby , Magdalena Scheck-Wenderoth New observations and modeling allow us to investigate the underlying processes responsible for volcanic and non-volcanic rift and passive margin formation. Key questions to be resolved include 1) what controls the amount and distribution of magmatism during volcanic to non-volcanic rift and passive margin formation. 2) How does magmatism impact the tectonic evolution of these systems and what are the structural and rheological controls of magmatism and feedbacks on tectonic deformation. 3) How are structural style of passive margin formation and magmatism linked? 4) What are the consequences of magmatic versus a-magmatic systems for the associated sedimentary basins? 5) What is the depositional environment for formation of seaward dipping reflector sequences and which processes control anomalous vertical motions during basin evolution? We encourage abstracts that offer new insights into processes underlying volcanic and non volcanic rift-passive margin formation from rift to ridge, using constraints from observations and modeling. TS6.1/GD5.6/GMPV2.12/SM1.24 Continental Rift Evolution: Tectonics, Topography, Transients https://protect-au.mimecast.com/s/n3PICq7BKYt2gP5viNfdye?domain=meetingorganizer.copernicus.org Conveners: Sascha Brune, Carmen Gaina, Corti Giacomo, Nick Kusznir Continental rifting is a multi-facetted process spanning from the inception of extension to continental rupture or the formation of a failed rift. This session aims at combining new data sets, concepts and techniques elucidating the structure and dynamics of rifts and rifted margins. We invite submissions highlighting the time-dependent evolution of processes such as initiation of faults and ductile shear zones, tectono-magmatic and sedimentary history, lithospheric necking and rift strength loss, influence of the pre-rift lithospheric structure, mantle dynamics and associated effects on rifting processes, as well as continental break-up and the transition to sea-floor spreading. We encourage contributions using multi-disciplinary and innovative methods from field geology, geochronology, seismology, geodesy, marine geophysics, plate reconstruction, or modeling. Focus regions may include but are not limited to the Atlantic, Indian Ocean, Mediterranean and South China Sea (e.g. IODP 367/368 area) rifted margins, or the East African, Eger, Baikal and Gulf of California rift systems. Special emphasis will be given to presentations that provide an integrated picture by combining results from active rifts, passive margins, failed rift arms or by bridging the temporal and spatial scales associated with rifting. SSP3.4 Understanding Source-to-Sink Systems from a Process-Based Perspective https://protect-au.mimecast.com/s/KfdjCr8DLRtmy0vOsNBY3p?domain=meetingorganizer.copernicus.org Conveners: Sara Mor?n, Mike Blum, William Helland-Hansen, Bj?rn Nyberg, Tor S?mme This session seeks to explore current research into sediment dispersal systems from a process-based and quantitative source-to-sink perspective. The study of source-to-sink systems relates long-term variations in sediment flux from source terrains to the morphological and stratigraphic evolution of depositional systems. These variations can reflect allogenic controls and/or autogenic self-organization over a wide range of time scales. Earth?s modern source-to-sink systems are becoming increasingly well characterized due to the proliferation and analysis of big data by academic researchers and industry scientists. Moreover, much progress has also been made transforming these insights into the potential for quantitative and predictive insights into the ancient stratigraphic record, but this remains a major challenge that requires integration of field data, numerical models, and experimental results. We invite contributions based on observation of field and remotely-sensed data as well as analogue and numerical modelling. We aim to cover a large range of autogenic and allogenic forcing mechanisms that operate on multiple time scales from the significance of individual transport events to the large-scale filling of sedimentary basins.

Understanding these processes is the key to unravelling the role plate tectonics plays in modulating Earth's geochemical cycles, atmospheric and ocean chemistry and climate. For this session we invite abstracts on any topic from monitoring and analysing tectonic, volcanic and metamorphic processes along plate boundaries, to topics focussed on modelling elemental fluxes along mid-ocean ridges and subduction zones through geological time. In addition, we invite contributions on the role of intraplate volcanism in this context. We also welcome abstracts on modelling regional or global geochemical cycles, particularly the deep carbon cycle, with a focus on connections with plate tectonics and geodynamics. The abstract deadline is 10 Jan 2019, 1300 CET, with abstract submission information available here: https://protect-au.mimecast.com/s/oMWbCwVLQmiN5z1nfQM6-7?domain=egu2019.eu Looking forward to seeing you in Vienna next year!

The abstract submission deadline of 10 January 2019, 13:00 CET. We hope to see you there! / /// /Session description:/ Many mantle structures have recently been observed by seismologists including the lithosphere-asthenosphere boundary (LAB), a possible transition near ~1000 km depth, small scale heterogeneities in the transition zone and in the lowermost mantle (ULVZ, D"), plumes, stagnating slabs, mantle anisotropy... However their origin is still unclear and geodynamical modelling can help propose plausible scenarios. Furthermore, geodynamic models and tomographic images often investigate different physical parameters, and propose views of the mantle at separate scales. Combining information from both fields is therefore necessary to understand and link mantle processes across scales. We encourage every contribution that can feed the dialogue between seismologists and geodynamicists.

Please note the abstract submission deadline of *10 January 2019*. GD7.2/EMRP2.19/SM4.18/TS11.8 *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. *Invited speakers: * *Stephen Beller (Geosciences Environnement Touluse)**Helena ?leb??kov?* * (The Czech Academy of Sciences, Prague)**Colton Lynner (Duke University, USA)* *Convener:* Manuele Faccenda *Co-conveners:* Sebastien Chevrot, Tuna Eken, Miriam Reiss -- Prof. Manuele Faccenda Associate Professor Dipartimento di Geoscienze, Universit? di Padova Via Gradenigo n. 6, 35131, Padova, Italy tel: +39 049 827 9159 website: https://protect-au.mimecast.com/s/A--JCD1jy9tZ5qz9tWviF6?domain=sites.google.com ----------------------------------------------------------------------------------------------- -------------- next part -------------- An HTML attachment was scrubbed...

In this session we commemorate the pioneering work of Kevin and contributions are invited from across the diverse fields that interested him, including Plate Tectonics and the Wilson Cycle at large, the origin of Precambrian greenstone belts, the evolution of the Caribbean and the uplift history of Africa. Kevin often asserted that plate tectonics is an incomplete theory without a clear understanding of its interaction with mantle plumes. He therefore set out to explore this issue more than a decade ago, and with collaborators proposed a simple conceptual mode where the link between plate tectonics and the Earth's deep mantle can be viewed as a simple mass-balance: subducted lithospheric slabs restore mass to the mantle and trigger a return flow toward the surface-including mantle plumes-rising from the margins of two stable and antipodal thermochemical piles in the lowermost mantle. The surface manifestations of plumes include large igneous provinces which punctuate the process of plate tectonics via the creation of new plate boundaries. We welcome contributions that examine surface and deep Earth links based on both observations and numerical models.
