S54B:
Seismic Anisotropy and Deformation in the Continental Crust III

Submit an Abstract to this Session



Session ID#: 32875

Session Description:
Seismic anisotropy in the continental crust has many causes, including oriented cracks, layering, and preferred crystallographic orientation of minerals. If crustal rock properties and their expressions in seismic data are well characterized, then observations of seismic anisotropy can be used to better understand the composition, structure, and deformation of the continental crust, which will be particularly useful in the deeper parts of the crust. We invite contributions focused on characterizing seismic anisotropy in the continental crust using multiple methods, including seismic methods (e.g. receiver functions, surface waves, shear-wave splitting, local earthquakes), laboratory methods (e.g. ultrasonic velocity measurements) and texture-determination methods (e.g. EBSD, X-Ray goniometry). We also invite contributions in deformation and shear localization, particularly bridging between microstructure and seismic wavelengths. Our aim is to have a highly interdisciplinary session in which seismic-, laboratory-, and field-based disciplines share knowledge with each other to improve our understanding of the continental crust.
