Much progress has been made over the past several decades in delineating the structure of
subducting slabs, but several key aspects of their dynamics remain poorly constrained …

Observations of seismic anisotropy yield some of the most direct constraints available on
both past and present-day deformation in the Earth's mantle. Insight into the character of …

We present a new global thermochemical model of the lithosphere and underlying upper
mantle constrained by state of the art seismic waveform inversion, satellite gravity (geoid …

Since the 1960s seismologists have mapped anisotropy in the uppermost mantle, the mantle
transition zone, and the D ″region. When combined with constraints from mineral physics …

We present a tomographic model of radially anisotropic shear velocity variations in the
Earth's mantle based on a new compilation of previously published data sets and a variable …

Various models of the origin of the asthenosphere are reviewed based on the latest
observations on mineral physics of mechanical properties, melting relationships and the …

We present a new global whole‐mantle model of isotropic and radially anisotropic S velocity
structure (SGLOBE‐rani) based on~ 43,000,000 surface wave and~ 420,000 body wave …

The variation of elastic-wave velocities as a function of the direction of propagation through
the Earth's interior is a widely documented phenomenon called seismic anisotropy. The …

SPiRaL is a joint global-scale model of wave speeds (P and S) and anisotropy (vertical
transverse isotropy, VTI) variations in the crust and mantle. The model is comprised of> 2.1 …

Azimuthal seismic anisotropy, the dependence of seismic wave speeds on propagation
azimuth, is largely due to fabrics within the Earth's crust and mantle, produced by …
