▪ Abstract Seismic anisotropy beneath continents is analyzed from shear-wave splitting
recorded at more than 300 continental seismic stations. Anisotropy is found to be a …

In this review of the rapidly growing literature on seismic anisotropy in the upper mantle, the
accent is put on the origin of this phenomenon. The predominant role of olivine is recalled. It …

We have made measurements of shear wave splitting in the phases SKS and SKKS at 21
broadband stations in North America, South America, Europe, Asia, and Africa …

Considerations from cosmochemistry and the study of meteorites permit us to place only
very broad bounds on the chemistry of the Earth's interior. These tell us little about the …

Building on global adjoint tomography model GLAD-M15, we present transversely isotropic
global model GLAD-M25, which is the result of 10 quasi-Newton tomographic iterations with …

The rotation of the Earth or Earth rotation, respectively, specifies the spatiotemporal change
of the Earth rotation vector. The direction of the Earth rotation vector corresponds to the …

We present a unique database of 110 olivine petrofabrics and their calculated seismic
properties. The samples come from a variety of the upper mantle geodynamic environments …

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 …

This paper reviews the evidence for deep continental structure and the arguments against
simple cooling-plate models as explanations of this structure. High-resolution seismological …
