Seismic and mechanical anisotropy and the past and present deformation of the Australian lithosphere

FJ Simons, RD van der Hilst - Earth and Planetary Science Letters, 2003 - Elsevier
We interpret the three-dimensional seismic wave-speed structure of the Australian upper
mantle by comparing its azimuthal anisotropy to estimates of past and present lithospheric …

3D modelling of electrical anisotropy from electromagnetic array data: hypothesis testing for different upper mantle conduction mechanisms

A Gatzemeier, M Moorkamp - Physics of the Earth and Planetary Interiors, 2005 - Elsevier
Upper mantle electrical conductivities provide, besides seismic velocities or thermal
diffusivities, another source of information on upper mantle structure and composition. We …

Electrical anisotropy below slow-and fast-moving plates: paleoflow in the upper mantle?

K Bahr, F Simpson - Science, 2002 - science.org
Upper mantle electrical conductivities can be explained by hydrogen diffusivity in hydrous

Development of texture and seismic anisotropy during the onset of subduction

JF Di Leo, AM Walker, ZH Li, J Wookey… - Geochemistry …, 2014 - Wiley Online Library
How reliable are shear wave splitting measurements as a means of determining mantle flow
direction? This remains a topic of debate, especially in the context of subduction. The …

Rayleigh–Taylor instabilities with anisotropic lithospheric viscosity

E Lev, BH Hager - Geophysical Journal International, 2008 - academic.oup.com
Rocks often develop fabric when subject to deformation, and this fabric causes anisotropy of
physical properties such as viscosity and seismic velocities. We employ 2-D analytical …

The influence of deformation history on the interpretation of seismic anisotropy

P Skemer, JM Warren, G Hirth - Geochemistry, Geophysics …, 2012 - Wiley Online Library
Seismic anisotropy in the mantle is primarily caused by the lattice‐preferred orientation
(LPO) of olivine, which forms and evolves in response to progressive plastic deformation …

[PDF][PDF] Deep Earth structure—upper mantle structure: global isotropic and anisotropic elastic tomography

JP Montagner - Treatise on geophysics, 2007 - academia.edu
Thirty years ago, the first global isotropic tomographic models of the mantle were published

Modeling the effect of subgrain rotation recrystallization on the evolution of olivine crystal preferred orientations in simple shear

J Signorelli, A Tommasi - Earth and Planetary Science Letters, 2015 - Elsevier
Homogenization models are widely used to predict the evolution of texture (crystal preferred
orientations) and resulting anisotropy of physical properties in metals, rocks, and ice. They …
