Abstract
Mineral assemblages in which chlorite [CHL], epidote [EPI], clinoamphibole [AMP], plagioclase [PLG] and quartz [QTZ] are major phases are characteristic of many low-grade mafic schists. The possible heterogeneous reactions in such an assemblage may be separated into two types, exchange reactions and net-transfer reactions. Only the latter alter significantly the modal proportions of the minerals.Keywords
