Phase relations in the system MgO‐FeO‐SiO2 were investigated between 22 and 47 GPa at 1500°C and 2000°C using multianvil apparatus with sintered diamond anvils. Synthesized samples were analyzed with electron microprobe, analytic transmission electron microscopy, and X‐ray diffraction using synchrot...
