The melting phase relations (melting curve of forsterite and binary eutectic composition) of the forsterite (Mg₂SiO₄)-pyrope (Mg₃Al₂Si₃O₁₂) system have been studied at 8 and 13.5 GPa. Forsterite is observed to melt incongruently into periclase + melt above about 8 GPa and the liquidus field of periclase gradually expands at higher pressures. The eutectic temperature is about 1850°C at 8 GPa and about 2100°C at 13.5 GPa, whereas the eutectic composition of the system is about 75 mol% forsterite at both pressures.
