Short summary
This paper presents the results of an exploratory study on the pressure–volumetemperature behaviour of the main Mg-phosphates of geological interest, especially in high-pressure metamorphic rocks. The incentive for it was the growing body of experimental phase-equilibrium data acquired at high pressure in the MgO–(Al2O3)–P2O5–H2O systems, the thermodynamic evaluation of which has been begging for such volumetric data.
