Experimental Geochemistry of Rock-Forming Minerals at High Temperatures and Pressures

这项工作包括重要的成岩硅酸盐和氧化物矿物的实验相平衡研究以及相关的热化学研究。该程序旨在生成端元矿物和固溶体的关键热力学参数，以及模拟地壳深部和上地幔的简单系统的压力和温度稳定性图。建议继续开展黑云母和石英与长石伴生和不伴生的熔融研究，以建立分析地壳深部熔融的实验框架。一个主要的浓度将是含有黑云母的简单体系在混合CO2-H2O蒸气下的熔融和固相线下的行为，以便为地球上流体过程的研究提供定量数据。

This work consists of a program of experimental phase equilibrium studies of important rock-forming silicate and oxide minerals with associated thermochemical studies. The program is designed to yield key thermodynamic parameters of end-member minerals and solid solutions, as well as pressure and temperature stability diagrams of simple systems modelling the deep crust and upper mantle. Melting studies of biotite and quartz with and without associated feldspars is proposed, continuing on preliminary work, to erect an experimental framework for analysis of deep-crustal melting. A principal concentration will be the melting and subsolidus behavior of simple systems with biotite under mixed CO2-H2O vapors, in order to provide quantitative data for the study of fluid processes in the earth.
