Structure and Evolution of the Oceanic Lithosphere and Mantle --- II Modeling
Session ID#: 77141
Session Description:
The movements of oceanic lithospheres organize flows in mantle convection while continental lithospheres, on average, are older and less involved in convective mass exchange. The structure and dynamics of the oceanic lithosphere and underlying mantle are important for understanding the Wilson cycle, hotspot tracks and oceanic plateaus. We welcome contributions from advances in data analysis, imaging and modeling to better understand the evolution of the oceanic domain in mantle convection. Example topics include but are not limited to: spreading center dynamics, lithosphere and mantle structure beneath mid-ocean ridges, heat flow measurements and geodynamical modeling, characteristics of mantle flow and seismic anisotropy in oceanic and continental domains, structures of the lithosphere-asthenosphere boundary (LAB), the 410-km and 660-km discontinuities in oceanic regions and comparative studies in continental settings, variations in volatiles and rheology and their implications for mantle convection, on land and offshore expeditions and the initiation of subduction.
