The crystal structure of the high-pressure Mg 2 Cr 2 O 5 phase was studied by single-crystal X-ray diffraction (XRD) analysis for the recovered samples. The 61 parameters including anisotropic displacement parameters of each atom and site occupancies

Earthquakes can occur at great depths in the Earth, within subducting tectonic plates. Deformation experiments suggest these deep earthquakes can be triggered by localized heating of the slabs under high pressures.

The role of aqueous fluid in fracturing in subducting slabs was investigated through a series of deformation experiments on dunite that was undersaturated (i.e., fluid-free) or saturated with water (i.e., aqueous-fluid bearing) at pressures of 1.0–

A new Al-bearing hydrous Mg-silicate that we named as 23 A phase was synthesized at 10 GPa and 1000 °C, while also coexisting with diaspore and pyrope in the following system: phase A [Mg7Si2O8(OH)6] + Al2O3 + H2O. The chemical composition of this n

We determined phase relations in MgCr2O4 at 12–28 GPa and 1000–1600 °C using a multi-anvil apparatus. At 12–15 GPa, spinel-type MgCr2O4 (magnesiochromite) first decomposes into a mixture of new Mg2Cr2O5 phase + corundum-type Cr2O3 at 1100–16

The silicate perovskite phase relation between CaSiO3 and MnSiO3 was investigated at 35–52 GPa and at 1,800 K using laser-heated diamond anvil cells combined with angle-dispersive synchrotron X-ray diffraction and energy-dispersive X-ray spectrosco

We determined phase relations in FeCr 2 O 4 at 12–28 GPa and 800–1600 °C using a multi-anvil apparatus. At 12–16 GPa, FeCr 2 O 4 spinel (chromite) first dissociates into two phases: a new Fe 2 Cr 2 O 5 phase + Cr 2 O 3 with the corundum struct

It has been repeatedly suggested that an iron-rich oxide might accumulate on the Earth's core-mantle boundary by various processes. Recent studies showed that FeO with a rock salt (B1)-type structure undergoes pressure- and temperature-induced metall

Spin transition and substitution of Fe3+ in Fe3+AlO3-bearing MgSiO3 perovskite (Pv) and post-perovskite (PPv) were examined up to 200 and 165 GPa, respectively, at room temperature by X-ray emission spectroscopy (XES) and XRD. The results of XES and
