英文摘要
9903026FischerThis project is to study continental seismic anisotropy, which has the potential to image patterns of lithospheric deformation and deeper mantle flow. The study will invert variations in fundamental mode Rayleigh wave phase and amplitude data across dense broadband arrays in order to place constrains on the depth and lateral distribution of mantle anisotropy. The study will compare these models against results from shear wave splitting in SKS and other teleseismic phases. The plan is to carry out these inversions in several regions: the eastern margin of the North American keel in the northeastern U.S. and southeastern Canada, the western margin of the North American keel in Colorado, the Colorado Plateau and Great Basin, and the Saudi Arabian Shield.
