To understand mantle dynamics, it is important to determine the rheological properties of
bridgmanite, the dominant mineral in Earth's mantle. Nevertheless, experimental data on the …

Wadsleyite is the dominant mineral of the upper portion of the Earth's mantle transition zone
(MTZ). As such, understanding plastic deformation of wadsleyite is relevant for the …

The dynamics of the Earth's mantle is still poorly constrained due to the lack of
understanding the transfer of matter between the upper and the lower mantle and their …

This work represents a numerical study of the thermal activation for dislocation glide of the
[100](010) slip system in MgSiO3 post-perovskite (Mg-ppv) at 120 GPa. We propose an …

The incorporation of water in nominally anhydrous minerals plays a crucial role in many
geodynamic processes and evolution of the Earth and affects the physical and chemical …

Creep strength of ringwoodite is important for understanding complicated patterns of the
mantle convection in and around the mantle transition zone. To determine the creep strength …

The rheology of eclogite, garnetite and clinopyroxenite in the peridotitic upper mantle was
experimentally investigated in a large volume press combined with in situ synchrotron X-ray …

The viscoplastic behavior of polycrystalline Mg $ _2 $ SiO $ _4 $ wadsleyite aggregates, a
major high pressure phase of the mantle transition zone of the Earth (depth range: 410--520 …

Thermally activated dislocation glide in Mg2SiO4 wadsleyite at 15 GPa has been modeled
to investigate its potential contribution to plastic deformation of wadsleyite in the Earth's …

We investigated the likelihood of radial anisotropy in the shallow and deep upper mantle,
including the mantle transition zone (MTZ) under the Indian Ocean. Seismic anisotropy can …
