Current deformation in the Tibetan Plateau: A stress gauge in the India‐Asia collision tectonics

FA Capitanio - Geochemistry, Geophysics, Geosystems, 2020 - Wiley Online Library
Geodetic velocities and mantle seismic anisotropy provide relevant constraints to the
dynamics of the Asian continent. Here, these are compared to numerical models of …

Evolving viscous anisotropy in the upper mantle and its geodynamic implications

Á Király, CP Conrad, LN Hansen - Geochemistry, Geophysics …, 2020 - Wiley Online Library
Asthenospheric shear causes some minerals, particularly olivine, to develop anisotropic
textures that can be detected seismically. In laboratory experiments, these textures are also …

Depth‐dependent azimuthal anisotropy beneath the Juan de Fuca plate system

ZC Eilon, DW Forsyth - Journal of Geophysical Research: Solid …, 2020 - Wiley Online Library
We use surface wave measurements to reveal anisotropy as a function of depth within the
Juan de Fuca and Gorda plate system. Using a two‐plane wave method, we measure phase …
