这一建议是为了支持理论研究， 检索F-和Cl-端元云母的热力学数据， 角闪石和其他阶段用于破译的行为 F和Cl在水热反应体系中的作用。 这些研究将 使限制被放置在物种和总 热液流体的卤化物含量基于已知的 硅酸盐矿物的组成。 此外还 可以预测F和Cl如何在矿物之间分配， 在水-岩相互作用过程中的含水流体， 分异作用在富F矿的形成过程中起着重要作用 存款 这项工作最重要的方面是 氟化物热力学性质的反演， 来自已发表的实验研究的氯化物端元矿物， 以及这些结果在地质问题中的应用。 的 研究范围将限于这些方面。

This proposal is for support of theoretical studies aimed at retrieving thermodynamic data for F- and Cl- endmember micas, amphiboles and other phases for use in deciphering the behavior of F and Cl in reacting hydrothermal systems. These studies will enable constraints to be placed on the speciation and total halide contents of hydrothermal fluids based on known compositions of silicate minerals. In addition, it will be possible to predict how F and Cl partitioned between minerals and aqueous fluids during water-rock interactions and whether this partitioning is important in the generation of F-rich ore deposits. The most important aspects of this work are the retrieval of the thermodynamic properties of fluoride and chloride end-member minerals from published experimental studies, and the application of these results to geologic problems. The scope of the research will be limited to these aspects.
