Mantle flow under the western United States from shear wave splitting

TW Becker, V Schulte-Pelkum, DK Blackman… - Earth and Planetary …, 2006 - Elsevier
We show that SKS splitting in the westernmost United States (polarization of the fastest
shear waves and splitting times, including their back-azimuthal dependence) can be …

Elastic anisotropy of D ″predicted from global models of mantle flow

AM Walker, AM Forte, J Wookey… - Geochemistry …, 2011 - Wiley Online Library
In order to test the hypothesis that seismic anisotropy in the lowermost mantle is caused by
the development of a post‐perovskite lattice preferred orientation, and that anisotropy can …

Mantle flow deflected by interactions between subducted slabs and cratonic keels

MS Miller, TW Becker - Nature Geoscience, 2012 - nature.com
Oceanic lithosphere is rapidly recycled into the mantle through subduction, an important part
of the dynamic evolution of the Earth. Cratonic continental lithosphere, however, can exist for …

Upper mantle seismic anisotropy as a constraint for mantle flow and continental dynamics of the North American plate

W Wang, TW Becker - Earth and Planetary Science Letters, 2019 - Elsevier
The alignment of intrinsically anisotropic olivine crystals under convection is typically
invoked as the cause of the bulk of seismic anisotropy inferred from shear-wave splitting …

Deformation in the lowermost mantle: From polycrystal plasticity to seismic anisotropy

HR Wenk, S Cottaar, CN Tomé, A McNamara… - Earth and Planetary …, 2011 - Elsevier
In the deep earth, deformation occurs at many scales: large-scale convection produces
subduction of slabs and upwelling of plumes in the mantle. At the high temperature/high …

The role of adria plate lithospheric structures on the recent dynamics of the central mediterranean region

R Lo Bue, M Faccenda, J Yang - Journal of Geophysical …, 2021 - Wiley Online Library

Insights on slab-driven mantle flow from advances in three-dimensional modelling

MA Jadamec - Journal of Geodynamics, 2016 - Elsevier
The wealth of seismic observations collected over the past 20 years has raised intriguing

On the relationship between oceanic plate speed, tectonic stress, and seismic anisotropy

E Kendall, M Faccenda, AMG Ferreira… - Geophysical research …, 2022 - Wiley Online Library
Seismic radial anisotropy (the squared ratio between the speeds of horizontally and
vertically polarized shear waves,) is a powerful tool to probe the direction of mantle flow and …

Superweak asthenosphere in light of upper mantle seismic anisotropy

TW Becker - Geochemistry, Geophysics, Geosystems, 2017 - Wiley Online Library
Earth's upper mantle includes a km thick asthenosphere underneath the plates where
viscosity and seismic velocities are reduced compared to the background. This zone of …
