用湿热氟缓冲技术测定了交换反应的平衡常数：OH-白云母 * HF 3F-白云母+ HrO。在2千巴的总压力下，log，K：2100/T - 0.1 I（T单位为开尔文）。这些数据与黑云母的类似数据相结合时，可用于评价共存黑云母和白云母之间的F= OH平衡。分配，这是独立的温度和流体成分，可以描绘成图形，并提供了一个简单的测试F* OH交换平衡的天然云母对。
Hycirothermal fluorine buffer techniques are used to measure the equilibrium constant for the exchange reaction: OH-muscovite * HF 3 F-muscovite + HrO. At a total pressure of two kbar, log ,K : 2lOO/T - 0.1 I (T in kelvins). These data, when combined with similar data for biotite, fermit evaluation of F= OH equilibrium between coexisting biotite and musco-vite. The partitioning, which is independent of temperature and fluid composition, may be portrayed graphically, and provides a simpie test of F* OH exchange equilibria in natural mica pairs.
