SEISMIC ANISOTROPY BENEATH THE CONTINENTS: Probing the Depths of Geology
Seismic anisotropy beneath continents is analyzed from shear-wave splitting recorded at more than 300 continental seismic stations. Anisotropy is found to be a ubiquitous property that is due toExpand

Shear wave splitting and subcontinental mantle deformation
splitting observations are interpreted in terms of the strain-induced lattice preferred orientation of mantle minerals, especially olivine. We consider three hypotheses concerning the origin of theExpand

The Interpretation of Shear‐Wave Splitting Parameters In the Presence of Two Anisotropic Layers
SUMMARY We consider the behaviour of shear-wave splitting parameters that are made under the assumption of a single layer of anisotropic material when in fact two layers of differing anisotropicExpand

The Subduction Zone Flow Field from Seismic Anisotropy: A Global View
Although the morphologies of subducting slabs have been relatively well characterized, the character of the mantle flow field that accompanies subduction remains poorly understood. To analyze thisExpand

Shear wave anisotropy beneath the Tibetan Plateau
Eleven broadband digital seismic stations were deployed across the central Tibetan Plateau in the first extensive passive-source experiment attempted within the Tibetan Plateau. One year of recordingExpand

Trench-Parallel Flow Beneath the Nazca Plate from Seismic Anisotropy
Shear-wave splitting of S and SKS phases reveals the anisotropy and strain field of the mantle beneath the subducting Nazca plate, Cocos plate, and the Caribbean region. These observations can beExpand

Implications for continental structure and evolution from seismic anisotropy
Evidence is presented for azimuthal anisotropy in the subcontinental upper mantle from nine stations in North America and Europe. For the stations in the Canadian Shield, this is due to 2.5–2.7Expand

Southern African crustal evolution and composition: Constraints from receiver function studies
[1] Stacking of approximately 1500 radial receiver functions recorded at about 80 broadband seismic stations deployed in southern Africa reveals systematic spatial variations in the ratio of crustalExpand

Seismic anisotropy of oceanic upper mantle: Shear wave splitting methodologies and observations
We develop methodologies to obtain accurate measurements of shear wave splitting and apply these techniques to examine the pattern of oceanic upper mantle anisotropy. To obtain high-quality estimatesExpand

Seismic anisotropy in the eastern United States: Deep structure of a complex continental plate
We have analyzed shear wave splitting recorded by portable and permanent broadband and long-period stations located in the eastern United States. Teleseismic shear waves (SKS, SKKS, and PKS) wereExpand
