TS4.5Geodynamics of collisional type orogenic belts and plateaus and its response to climate and erosional process - Himalaya, Pamir, Central Asia & Tibet
|Convener: R. Thiede | Co-Conveners: M. Fuchs , M. Allen|
Large collisional orogenic belt are characterized by high topography, tectonically thickened crust that is thermally weakened at a mid-crustal depth and forming a paradigm for deep crustal processes. The thickened crusts is expressed by extended high-elevated mountain plateaus, which affect global atmospheric circulation pattern and establish strong deformational, climatic as well as erosion gradients along their margins. To which degree they interact, develop feedbacks or trigger each other is still strongly debated. This session will bring together researchers interested in developing new insights and quantify relationships between tectonics, topography and erosion, as well as share models that capture the structural and topographic evolution of continental collision zone. We invite submissions focusing on, but not restricted to, models of deformation and uplift processes within large collision zones and the testing of such models via geochemical, geochronological, geodetic, geophysical, modeling, metamorphic, and/or structural investigations.
