Lithospheric drip
WebHere we integrate seismic anisotropy data with tomographic images to identify and describe a lithospheric drip beneath the Great Basin region of the western United States. The feature is characterized by a localized cylindrical core of cooler material with fast seismic velocities and mantle flow that rapidly shifts from horizontal to vertical. WebCommon lithospheric viscosities and observed timescales indicate that both instability transitions are feasible. Overall, the timescale and persistence of delamination depends …
