Seismic anisotropy has been found in many regions of the Earth's interior. Its presence in the
Earth's crust has been known since the 19th century, and is due in part to the alignment of …

Convection provides the mechanism behind plate tectonics, which allows oceanic
lithosphere to be subducted into the mantle as “slabs” and new rock to be generated by …

The rheological properties of Earth's lower mantle play a key role for global mantle
dynamics. The mineralogy of the lower mantle can be approximated as a bridgmanite …

Crystallographic preferred orientation (CPO) of post-perovskite (Mg, Fe) SiO3 (pPv) has
been believed to be one potential source of the seismic anisotropic layer at the bottom of the …

Seismic anisotropy in Earth's lowermost mantle, resulting from Crystallographic Preferred
Orientation (CPO) of elastically anisotropic minerals, is among the most promising …

Transport of heat from the interior of the Earth drives convection in the mantle, which
involves the deformation of solid rocks over billions of years. The lower mantle of the Earth is …

We present an improved setup for the experimental study of deformation of solids at
simultaneous high pressures and temperatures by radial x-ray diffraction. This technique …

The presence of water in lower mantle minerals is thought to have substantial effects on the
rheological properties of the Earth's lower mantle in what is generally known as “hydrolytic …

The long‐wavelength geoid is sensitive to Earth's mantle density structure as well as radial
variations in mantle viscosity. We present a suite of inversions for the radial viscosity profile …

A bridgmanite/periclase aggregate is investigated due to its prevalence in the Earth's lower
mantle and its importance for understanding geodynamic processes. In dual-phase …
