Solubility of Apatite in Aluminosilicate Melts of the Albite-Diopside, Anorthite-Diopside, and Orthoclase-Diopside Systems

摘要

The liquidus surface temperatures, eutectic temperatures and compositions, phase crystallization fields, and phase separation regions are determined for the albite-apatite, anorthite-apatite, orthoclase-apatite, diopside-apatite, albite-diopside-apatite, anorthite-diopside-apatite, and orthoclase-diopside-apatite systems. The influence of the composition of the silicate melt on the solubility of apatite is described in a mathematical form. A program of calculating the limiting solubility of apatite in the silicate melt is developed.
