Abstract
Rb occurs as a minor element in a variety of igneous, metamorphic and sedimentary rocks. Muscovite is along with K-feldspar and biotite one of the most important host minerals for Rh. Voncken et al. (1967) describe a pure synthetic Rb-analogue of 2M1 muscovite. The Rb-analogue of muscovite can be formed stably at 600 °C and 2, 3, 5 and 15 kbar (Voncken, unpubl. data). Several experimental studies on K-Rb exchange reactions between hydrothermal fluid and K-feldspar or phlogopite are reported (Beswick, 1973; Volfinger, 1974, 1976). There are relatively few exchange data for muscovite (Volfinger, 1969, 1976).
