Abstract
Three single crystals of CaTi2O4 (CT)-type, CaFe2O4 (CF)-type, and new low-density CaFe2O4 (LD-CF) related MgAl2O4 were synthesized at 27 GPa and 2500 °C and also CT-type MgAl2O4 at 45 GPa and 1727 °C using conventional and advanced mul...

We precisely determined detailed phase relations of upper continental crust (UCC) at 20-28 GPa and 1200-1800 degrees C across the 660-km discontinuity conditions with a high-pressure multi-anvil apparatus. We used multi-sample chambers packed with...

Phase relations in the system TiO2-ZrO2 were examined in the pressure range of 3.5-12 GPa at 1,800 degrees C, using multianvil apparatus. At 1,800 degrees C, TiO2 rutile transforms to alpha PbO2 structure at 10 GPa, and the alpha PbO2-type solid s...
Isobaric heat capacities (C-p) of Mg2SiO4 forsterite and ringwoodite were measured by differential scanning calorimetry in the temperature range of 306-833 K. The measured C-p of Mg2SiO4 forsterite was consistent with those reported by previous st...
