Seismic anisotropy and mantle deformation: what have we learned from shear wave splitting?
MK Savage - Reviews of Geophysics, 1999 - Wiley Online Library
Shear wave splitting measurements now allow us to examine deformation in the lithosphere
and upper asthenosphere with lateral resolution< 50 km. In an anisotropic medium, one …

Lower crustal anisotropy or dip** boundaries? Effects on receiver functions and a case study in New Zealand
MK Savage - Journal of Geophysical Research: Solid Earth, 1998 - Wiley Online Library
We examine the effects on receiver functions of transverse anisotropy and of dip**
isotropic boundaries. Splitting of the Moho Ps phase predicts the anisotropy from a …

Receiver functions from multiple-taper spectral correlation estimates
Teleseismic P waves are followed by a series of scattered waves, particularly P-to-S
converted phases, that form a coda. The sequence of scattered waves on the horizontal …

P-SH conversions in a flat-layered medium with anisotropy of arbitrary orientation
P-SH conversion is commonly observed in teleseismic P waves, and is often attributed to
dip** interfaces beneath the receiver. Our modelling suggests an alternative explanation …

Seismic anisotropy: tracing plate dynamics in the mantle
Elastic anisotropy is present where the speed of a seismic wave depends on its direction. In
Earth's mantle, elastic anisotropy is induced by minerals that are preferentially oriented in a …

Crustal fabric in the Tibetan Plateau based on waveform inversions for seismic anisotropy parameters
HF Sherrington, G Zandt… - Journal of Geophysical …, 2004 - Wiley Online Library
The Tibetan Plateau has the thickest continental crust on Earth, and fabrics within the crust
that are anisotropic to seismic waves may provide clues to how it reached such extreme …
