Stress-dependent shear wave splitting and permeability in fractured porous rock

Journal of Rock Mechanics and Geotechnical Engineering, 2019
It is well known that shear wave propagates slower across than parallel to a fracture, and as a result, a travelling shear wave splits into two directions when it encounters a fracture.

Upper crustal anisotropy from local shear-wave splitting and crust-mantle coupling of Yunnan, SE margin of Tibetan Plateau

Geodesy and Geodynamics, 2018
The upper crustal anisotropy of Yunnan area, SE margin of Tibetan Plateau, is investigated by measuring the shear wave splitting of local earthquakes.

Mantle flow through a tear in the Nazca slab inferred from shear wave splitting

Geophysical Research Letters, 2017
A tear in the subducting Nazca slab is located between the end of the Pampean flat slab and normally subducting oceanic lithosphere. Tomographic studies suggest mantle material flows through this opening.

Observations of Mantle Seismic Anisotropy Using Array Techniques: Shear‐Wave Splitting of Beamformed SmKS Phases

Journal of Geophysical Research: Solid Earth, 2022
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 phases that have reflected (m‐1) times off the underside of the core‐mantle boundary ...

Mantle dynamics in the SE Tibetan Plateau revealed by teleseismic shear-wave splitting analysis

Physics of the Earth and Planetary Interiors, 2021
The tectonic evolution of the southeastern Tibetan Plateau is key to understanding the mechanism of growth of the whole Tibetan Plateau. Its imprint on lithospheric and asthenospheric mantle rock fabrics is expected to have a strong signature on seismic ...

High temperature elastic anisotropy of the perovskite and post-perovskite polymorphs of Al2O3 [PDF]

, 2005
Finite temperature ab initio molecular dynamics calculations were performed to determine the high temperature elastic and seismic properties of the perovskite and post-perovskite phases of pure end-member Al2O3.

Wave speeds and Green’s tensors for shear wave propagation in incompressible, hyperelastic materials with uniaxial stretch [PDF]

, 2019
Assessing elastic material properties from shear wave propagation following an acoustic radiation force impulse (ARFI) excitation is difficult in anisotropic materials because of the complex relations among the propagation direction, shear wave ...

Comment on “SKS splitting beneath continental rifts zones” by Gao et al. [PDF]

, 1999
International audienceAs previously suggested by many authors, shear wave splitting rneasurernents certainly provide the best insights on the tectonic structure (or fabric) of the upper mantle.

Mid-mantle deformation inferred from seismic anisotropy [PDF]

, 2002
With time, convective processes in the Earth's mantle will tend to align crystals, grains and inclusions. This mantle fabric is detectable seismologically, as it produces an anisotropy in material properties—in particular, a directional dependence in ...
