Abstract
Below 6 GPa, MgGeO (sub 3) transforms with increasing P from an orthopyroxene, to a clinopyroxene, and finally to an ilmenite structure. Thermodynamic parameters for MgGeO (sub 3) (opx arrow right cpx) and MgGeO (sub 3) (cpx arrow right ilm) have been constrained by high-T solution calorimetric experiments, lattice vibrational calculations, and phase-equilibrium studies.
