... pressure is very important for understanding water transport in the Earth’s interior. In this work, we conducted Raman scattering and luminescence spectroscopic experiments on δ-AlOOH at pressures up to 34.6 and 22.1 GPa, respectively. From the collected Raman spectra, significant changes in the pressure...

... in controlling dynamic processes in the deep interiors of the Earth and other planets. The correlation between structural and macroscopic properties of silicate liquids (densification, viscosity, chemical differentiation, etc.), however, remains poorly understood. Here we report the evolution of structural...

.... Better understanding of properties of melts at high pressure is critical to evaluate the nature and the fate of melts generated in the deep mantle. In the early Earth, melt properties controlled the crystallization of the magma ocean, which induced chemical segregation and evolution of the interior...

...Dipta B. Ghosh; Bijaya B. Karki; Jianwei Wang Abstract Grain boundaries in mantle minerals are of critical importance to geophysical and geochemical processes of the Earth’s interior. One of the fundamental issues is to understand how the water (H 2 O) component influences the properties of grain...

This is very likely due to the dehydration of the amphibole-bearing rock sample, which generates two conductive phases operating in series, i.e., the original solid phase and the aqueous fluid phase interconnected along the grain...

...Xueyin Yuan; Robert A. Mayanovic; Guoliang Zhang Abstract The transport of calcium carbonate (CaCO 3 ) into the Earth’s interior through subduction is one of the key processes in the global cycling of carbon. To develop a better understanding of the CaCO 3 structural stability during subduction...

... enriched with Mg under pressure. Studying Mg-bearing aluminosilicate glasses can thus help us to better understand the behavior of magma deep in the interior of the Earth. (2) Q = 4 π E sin θ h c = 4 π sin θ λ where λ is the X-ray wavelength, E is the X-ray energy...
