Small Shear Wave Splitting Delays Suggest Weak Anisotropy in Cratonic Mantle Lithosphere
Geophysical Research Letters, 2021 We use splitting in core‐refracted teleseismic shear waves (SKS, PKS, and similar) to investigate anisotropic properties of the upper mantle beneath the Superior craton in eastern North America and the Yilgarn craton in Western Australia.

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.

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.

Preliminary analysis of crustal shear‐wave splitting in the Sanjiang lateral collision zone of the southeast margin of the Tibetan Plateau and its tectonic implications [PDF]
Geophysical Prospecting, 2019 The collision of the Indian and Eurasian plates, to the east of the eastern Himalayan syntaxes, forms the Sanjiang lateral collision zone in the southeast margin of the Tibetan Plateau, where there are intense crustal deformation, active faults ...

Reviews on seismic anisotropy based on shear-wave splitting in the Tibetan Plateau
地球与行星物理论评, 2021 The research on the anisotropy of shear wave splitting in the Tibetan Plateau has been carried out for nearly 30 years, and important progress has been made in theoretical methods and practical applications. A large number of shear wave splitting results

Shear-Wave Splitting Analysis Using Optimization Algorithms
Lithosphere, 2022 Shear-wave splitting (SWS) analysis is used to predict fractures in subsurface media. Specifically, two parameters relevant to SWS analysis (the azimuth of the fast shear wave and the time delay between the fast and slow shear waves) are used to quantify

Effects of Background Porosity on Seismic Anisotropy in Fractured Rocks: An Experimental Study
Applied Sciences, 2023 Fractures are widely distributed in the subsurface and are crucial for hydrocarbon, CCS, offshore infrastructure (windfarms), and geothermal seismic surveys.

Anisotropic structure of the Australian continent
Frontiers in Earth Science, 2023 The Australian continent preserves some of the oldest lithosphere on Earth in the Yilgarn, Pilbara, and Gawler Cratons. In this study we present shear wave splitting and Ps receiver function results at long running stations across the continent.

Seismic anisotropy of the upper mantle beneath Thailand: Tectonic setting constrained by shear-wave splitting analysis [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2020 The tectonic setting of the lithosphere and upper mantle underneath Thailand varies and changes substantially over short distances. We have mapped these variations using shear wave splitting (SWS) analysis.
