ACTIVITY-COMPOSITION RELATIONSHIPS FOR PYROPE-GROSSULAR GARNET
Activity coefficients (γ) for grossular in pyrope-grossular garnet have been determined experimentally using the divariant assemblage garnet-anorthite-sillimanite (kyanite)-quartz. Values of γ for garnets with 10-12 mole % grossular have been obtained at 1000 °, 1100 °, 1200 ° and 1300 ° C at pressu...

| description | Activity coefficients (γ) for grossular in pyrope-grossular garnet have been determined experimentally using the divariant assemblage garnet-anorthite-sillimanite (kyanite)-quartz. Values of γ for garnets with 10-12 mole % grossular have been obtained at 1000 °, 1100 °, 1200 ° and 1300 ° C at pressures between 15 and 21 Kb. The data are consistent with a symmetrical regular solid model for grossular-pyrope solid solutions. The interaction parameter (W) increases linearly with decreasing temperature and is given by W = 7460-4.3 T cals (T in °K). A solvus in the pyrope-grossular solid solution is predicted with a temperature of critical mixing of 629°C±90 ° C. © 1975 Springer-Verlag. |
