Convective flow in the deep mantle controls Earth's dynamic evolution, influences plate
tectonics, and has shaped Earth's current surface features. Present and past convection …

We compile and make publicly available a global digital database of body wave
observations of seismic anisotropy in the D′′ layer, grouped using the method used to …

Seismic anisotropy has been detected at many depths of the Earth, including its upper
layers, the lowermost mantle and the inner core. While upper mantle seismic anisotropy is …

Shear‐wave splitting measurements are commonly used to resolve seismic anisotropy in
both the upper and lowermost mantle. Typically, such techniques are applied to SmKS …

Determinations of seismic anisotropy, or the dependence of seismic wave velocities on the
polarization or propagation direction of the wave, can allow for inferences on the style of …

Observations of seismic anisotropy at the base of the mantle are abundant. Given recent
progress in understanding how deformation relates to anisotropy in lowermost mantle …

It is well known that regions of the lowermost mantle—D ″—exhibit significant seismic
anisotropy. Identifying a unique mechanism for seismic anisotropy in D ″and interpreting …

Abstract The Yellowstone region (western United States) is a commonly cited example of
intraplate volcanism whose origin has been a topic of debate for several decades. Recent …

Observations of seismic anisotropy just above the core‐mantle boundary are a powerful way
to understand the dynamics of the lowermost mantle. Here we present models of seismic …

The geology of southern New England reflects subduction and terrane accretion during the
Appalachian Orogeny and rifting during the breakup of Pangea. The presence of a low …
