For quartz-rich tectonites two types of deformation thermometer are currently commonly
employed: 1) The quartz c-axis fabric opening-angle thermometer that provides an estimate …

A robust knowledge of seismic anisotropy beneath the continents is essential to our
understanding of plate tectonic theory, as anisotropy provides a unique constraint on the …

Observations of seismic anisotropy yield some of the most direct constraints available on
both past and present-day deformation in the Earth's mantle. Insight into the character of …

Knowledge about seismic anisotropy can provide important insight into the deformation of
the crust and upper mantle beneath tectonically active regions. Here we focus on the …

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 …

Elasticity is described in general by a fourth-order tensor with 21 independent coefficients,
which corresponds to the triclinic symmetry class. However seismological observations are …

Accurately inferring the radially anisotropic structure of the mantle using seismic waveforms
requires correcting for the effects of crustal structure on waveforms. Recent studies have …

Viscous shear in the asthenosphere accommodates relative motion between Earth's surface
plates and underlying mantle, generating lattice‐preferred orientation (LPO) in olivine …

This study provides a comprehensive review of the crystal preferred orientation (CPO) of
olivine and orthopyroxene in the upper mantle, and of several hydrous minerals in the …

A continental-scale, low seismic velocity anomaly in the mid to lower mantle beneath Africa
is a robust feature of global tomographic models. Assuming the low velocities are associated …
