SE11.01 Convergent margins: Seismic images and geophysical signatures at subduction zones

Event Information

The evolution of convergent margins is governed by complex and coupled processes which lead to a highly diverse structure. Geophysical and geodynamical studies of active and ancient systems are aimed at understanding these processes, e.g.: - Active tectonics and associated mass and fluid flux (e.g. sediment subduction and accretion, fluid flow, subduction erosion) - Thermal and mechanical structure of subducting and overriding plates (e.g. the seismogenic zone, influence of the ocean plate structure on subduction, modelling of fluid flow, metamorphic processes) -Methods and/or studies for improved imaging of the structure subduction zones (e.g. 3-d earthquake/active source tomography) -Field studies of onland exposures of exhumed analogues (e.g. tectonic melanges) -Onshore geophysical studies of ancient convergent margins (e.g. seismic studies in cratons and shields). We encourage submission of contributions on these and related topics.
