... is estimated to be ~0.54–1.10 wt% and ~0.10–0.22 wt%, respectively. These results suggest that the Earth’s core may be a potentially large reservoir of water, with up to ~98 times as much as oceans of water being brought to the Earth’s interior during its formation. Based on our predicted hydrogen content...

... 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...

... Geodynamic models developed since the acceptance of plate tectonics have followed the early concepts of Earth structure envisaged by Barrell (1915) of a strong outer shell (lithosphere) overlying a deformable interior layer (asthenosphere). Plate-tectonic theory divided the lithosphere into segments...

.... 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...

... in the low-frequency range (Online Materials 1 Fig. OM3). The separation of the two arcs possibly indicates two conductive paths: one through the grain interior and the other along the grain boundary. This is very likely due to the dehydration of the amphibole-bearing rock sample, which generates two...
