Garnet EoS: a critical review and synthesis

All available volume and elasticity data for the garnet end-members grossular, pyrope, almandine and spessartine have been re-evaluated for both internal consistency and for consistency with experimentally measured heat capacities.

The consistent data were then used to determine the parameters of third-order Birch–Murnaghan equation of state (EoS) to describe the isothermal compression at 298 K and a Mie–Grüneisen–Debye thermal-pressure EoS to describe the PVT behaviour.
