The facies series of the glaucophanitic Sangun metamorphic belt, Southwest Japan, consists of, from lower to higher grade, the pumpellyite-actinolite zone, the epidote -glaucophane zone and the barroisite zone. The last zone is observed only in the Nichinan cho district, Tottori Prefecture. The geology and mineral parageneses of this district have been described by Miyakawa (1961), Igi and Abe (1964) and Hashimoto (1973). The area is underlain mostly by pelitic schist along with a few beds of basic and quartzose schists. The metamorphic grade corresponds to that of the lower temperature part of the epidote amphi bolite facies, and all the schists there carry abundant porphyroblasts of albite. Chemical analyses of two barroisites and their host basic schists were published in 1973 by the present writer, and this time analyses of chlorites, muscovites and their host pelitic schists and of chlorites and epidote of basic barroisite schists are given.
