From dietmar.muller at sydney.edu.au Mon Nov 11 08:31:12 2019 From: dietmar.muller at sydney.edu.au (Dietmar Muller) Date: Sun, 10 Nov 2019 21:31:12 +0000 Subject: [Geodynamics] EGU2020 session: Progress in observational and theoretical geodynamics Message-ID: GD1.2 Progress in observational and theoretical geodynamics The last two decades have seen tremendous growth in the range of geodynamically relevant observations, including, but not limited to detailed tomographic imaging of the deep Earth from the sublithosphere to the CMB to provide state estimates of the convective system, noise mitigated plate motion reconstructions that reveal temporal velocity variations of tectonic plates much faster than the mantle transit time, stratigraphic analysis to expose systematic changes at the continental scale in the distribution of hiatus at the level of series and stages, and paleomagnetic investigations that map rapid bursts in the motion of some hotspots, all together documenting the relentless convective activity of Earth's mantle and its impact throughout the Earth system. At the same time powerful geodynamic inversion techniques based on the adjoint and other optimisation methods have become available to link models and data quantitatively through variational and sequential assimilation schemes of observations into geodynamic simulations. The simultaneous growth of observations and theoretical capabilities provides us with unprecedented opportunity to test the underlying assumptions of dynamic Earth models. This transdisciplinary session brings together observational and theoretical scientists to discuss the scope and format of established and nascent convection related observables, and welcomes contributions that highlight the noisy nature of observables while exploring methods to handle the impact of uncertainty in the geodynamic data assimilation framework.

Dear Colleagues, We would like to invite you tosubmit an abstract to our session at the?EGU General Assembly (May 3-7, 2020)entitled?Lithospheric localization processes across scales: from fault dynamics to plate boundary formation and evolution??(GD9/TS2). Session description: https://protect-au.mimecast.com/s/23JxCJyp0qhGL0D7tVZXlK?domain=meetingorganizer.copernicus.org Conveners: Lukas Fuchs, Ma?lis Arnould, Whitney Behr, Eline Le Breton. This year?s keynote speakeris Manon Bickert, IPGP, France. In the Plate Tectonics theory, Earth?s lithosphere is described as a rigid outermost shell deforming over long timescales along narrow boundaries, that play a central role in our Planet?s thermal and dynamic evolution. Understanding the modalities of strain localization in the lithosphere and its failure are therefore essential to describe the formation and evolution of plate boundaries, fault zones and other mechanical heterogeneities. This requires knowledge of localization processes at both micro- and macro-physical scales, the analysis of their dynamics over various time scales, and involves complementary inputs from geological and seismic observations, laboratory experiments and numerical and analog modeling. We welcome multidisciplinary contributions that will collaboratively help to build a unified view on the dynamical evolution of lithospheric localization processes. Example topics include but are certainly not limited to the study of variations in lithospheric properties deduced from mineralogical, petrological or geological data, and of the implication of lithospheric anomalieson the dynamics of fault zonesand the formation and evolution of plate marginsin nature or in models.

Important dates: - Deadline for financial support applications: 1st December 2019, 1pm CET - Deadline for abstract submission: 15th January, 2020, 1pm CET *Session description:* 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.
