Density of hydrous silicate melt at the conditions of Earth's deep upper mantle
Article Abstract:
The chemical evolution of the Earth and the terrestrial planets is largely controlled by the density of silicate melts and if melt density is higher than that of the surrounding solid, incompatible elements dissolved in the melt would be sequestered in the deep mantle. The water in the silicate melt is more compressible than the other components, and therefore the effect of water in reducing melt density is markedly diminished under high-pressure conditions.

Iron-silica interaction at extreme conditions and the electrically conducting layer at the base of Earth's mantle
Article Abstract:
A simulation of the temperatures and pressures at the core-mantle boundary of Earth suggests that the iron-silica interaction in these conditions could account for that area's unusually high electrical conductivity.

Chemical interaction of Fe and AL2O3 as a source of heterogeneity at the Earh's core-mantle boundary
Article Abstract:
Research describing the interaction of iron and corundum at high temperature and pressure is presented. In particular simulated conditions in the interior of the Earth are investigated.
