摘要
本文根据前人关于云母和黄玉的F－OH交换实验成果，分别建立了云母和黄玉的F－OH交换平衡常数方程，并系统阐述了推导这些方程的热力学原理以及利用它们来估算云母＋黄玉平衡组合形成温度和共存流体组成的方法，最后讨论了这一方法的适用条件和存在问题。
The experimental results of Munoz et al. (1974, 1977, 1984) and Rosenberg (1978) are used to establish the equilibium constant equations of F-OH exchange in micas and topaz. The ther-modynamic principles concerned are systematically expounded. Those equations can be used to cal-culate the forming temperatures and co-existing fluid compostiton-lg (fH2o/fHF) of mica +topaz as-semblage. The errors or uncertainties involved in and the suitable conditions for this method of cal-culation are discussed as well.
