The relative stability of MgSiO3-ilmenite , MgSiO3-perovskite and (periclase+stishovite) assemblage phases as a function of the pressure is investigated with the periodic quantum mechanical ab initio Hartree-Fock program CRYSTAL. For the first time, the structure of MgSiO3-ilmenite is fully optimize
Raman spectra of )J-Mg2SiO4 taken to 200 kbar were used to calculate entropy and heat capacity at various P-Tconditions. These new thermodynamic data on ~-MgSiO4, similar data on MgSiO 3 perovskite (pv), previous data on fl-MgSiO 4 and MgO (row), and previous volumetric data of all phases were used
