DI51D:
Advances in Understanding Earth's Dynamic Processes Using Seismic Anisotropy II

Submit an Abstract to this Session



Session ID#: 32057

Session Description:
Understanding the process and evolution of mantle dynamics represents a fundamental goal of Earth science. However, this has also been a major challenge due to the inaccessible nature of the solid Earth and the various uncertainties in observation and modeling. Recent advances on measuring seismic anisotropy using different geophysical methods generate new constraints on deformation of the Earth’s interior associated with active subduction, lithosphere deformation, mantle circulation, core-mantle boundary processes, as well as the growth of the inner core. Meanwhile, novel analog and numerical modeling techniques and capabilities start to be able to capture the Earth’s dynamic processes at unprecedented levels of resolution and physics. Consequently, new perspectives emerge on the evolution of the crust, lithosphere, mantle, and core. Therefore, we invite submission with a focus on the deformation and structures of the solid Earth from seismic and MT measurements, laboratory simulation, theoretical calculation, and geodynamic modeling.
