Dear all, We would like to encourage you to submit an abstract to our session at the 33 IGC in Oslo in August: GDP-07 Coupling lithosphere and mantle processes Our aim is to discuss processes in the lithosphere and mantle and the interaction between the two domains from the perspective of a large range of disciplines, including numerical models, laboratory models, geochemistry and structural geology. We have three invited lectures: Thorsten Becker (University of Southern California): The dynamics of the asthenosphere inferred from residual seismic anisotropy Jeroen van Hunen (University of Durham): Consequences of small-scale convection in oceanic lithosphere Paul Tackley (ETH Zurich): Treating tectonic plates and mantle convection as a single, integrated system: Simulations in 3D spherical geometry We look forward to seeing you in Oslo! Susanne Buiter and Bernhard Steinberger ---- GDP-07 Coupling lithosphere and mantle processes (Interdisciplinary Symposia, Geodynamics and Plate Motions) Processes such as the formation of fold-and-thrust belts or convection in Earth's mantle have successfully been investigated for the lithosphere and the underlying mantle as separate domains, but mostly without considering mutual influence. However, it is well known that mantle flow drives lithosphere deformation on a large scale, while lithosphere processes such as subduction in turn impact mantle flow. To understand such interactions between mantle and lithosphere, it is necessary to bridge the differences in scale between both domains, while also taking their different material behaviour into account. The aim of this session is to discuss processes in the lithosphere and mantle, the (technical) challenges in linking the two domains and examples of coupled processes, as for example, mantle plumes and lithosphere deformation, dynamic and isostatic topography and subduction zone dynamics. We welcome contributions from all disciplines, including numerical models, laboratory models, geochemistry and structural geology.
