Phase Equilibria and Solution Modelling of Silicates and Oxides

该项目将继续研究许多矿物的相平衡，这些矿物可以提供有关温度、压力和氧逸度的信息，在这些信息下，含有它们的岩石会结晶。一个重要的新进展是纳入熔化现象，为熔体的热力学建模提供必要的信息。方法是进行反相平衡实验，然后将热力学溶液模型应用于这些实验的结果。溶液模型允许将结果应用于实验未涵盖的成分、温度、压力和氧逸度。

This project will continue investigations of the phase equilibria of a number of minerals that can provide information as to the temperature, pressure, and oxygen fugacity under which the rocks containing them crystallized. An important new thrust is the inclusion of melting phenomena to provide essential information for thermodynamic modelling of melts. The approach is to perform reversed phase-equilibrium experiments and then to apply thermodynamic solution modelling to the results of those experiments. The solution models permit application of the results to compositions, temperatures, pressures, and oxygen fugacities not covered by experiment.
