Experimental Data for understanding melting and phase relations at the Mercury silicate mantle compositions as a function of temperature at 7 GPa

High pressure-temperature experiments were performed at 7 GPa and 1700-2100 C using a cubic press to understand melting relations at the core-mantle boundary on Mercury. Mer8 was in the stability field of orthopyroxene whereas Mer15 first crystallized olivine. With cooling, both compositions reached a cotectic surface with olivine + orthopyroxene, followed by garnet and clinopyroxene. A sulfide phase (FeS + MgCaFeS) was present in all experiments.
