Outline of Final Research Achievements

It is expected from high-pressure high-temperature experiments that calcium ferrite-type NaAlSiO4 exists in subducted oceanic plates in the lower mantle. Heat capacity at constant pressure and entropy of calcium ferrite-type NaAlSiO4 were estimated theoretically based on information about the lattice vibration, which was obtained by Raman spectroscopic measurements at 1 atm and high pressures.
(Mg,Fe)GeO3 perovskite solid solution is a good analogue of (Mg,Fe)SiO3 perovskite which is the most abundant mineral in the Earth’s lower mantle. We obtained data with relation to compositional dependency of lattice vibration of the (Mg,Fe)GeO3 perovskite by performing high-pressure Raman spectroscopy.
