Fig. 4From: Melting phase relations in the MgSiO3–CaSiO3 system at 24 GPaBackscattered electron images for the samples recovered from high pressure and high temperature (Run No. OS3099). In Mg90, a quenched melt was found at the hottest region surrounded by bridgmanite (Bdg), which is interpreted as the liquidus phase. In contrast, CaSiO3-rich perovskite (CaPv) was found to be segregated in Mg75. We failed to find the melt. The subsolidus phase assemblage was observed at the central (cold) part of both samplesBack to article page
