| Research Abstract |
Phase equilibrium relations of spinel-postspinel transitions of mantle minerals have been precisely determined in the mineral compositions and in pyrolite by high-pressure high-temperatureexperiments and calorimetry. Perovskite- postperovskite transitions have been found in several compounds at high pressure. The crystal structures of postperovskite-type compounds were analyzed and their physical properties were measured.
