A low pressure investigation of the stability of phlogopite

January 1, 1967

Phlogopite reacts to form orthorhombic kalsilite, leucite, forsterite and fluid (H2O) at 1012 ± 7°C, 400 bars pressure, and 905 ± 5°C at 100 bars pressure. The heat of reaction is 39 ± 4 kcal compared to 44 ± 6kcal for the reaction of annite to form orthorhombic kalsilite, leueite, fayalite and fluid (H2O). The results are consistent with earlier experiments, but not with the interpretations of those experiments.
