Abstract

Minor metamorphic Ca-Na pyroxene occurs as minute crystals and as thin rims around primary augites in metabasites intermediate between the prehnite-pumpellyite and pumpellyite-actinolite facies in the Sanbagawa belt, Shikoku, Japan. From the mineral parageneses in the metabasites of the Sanbagawa belt and elsewhere, it is concluded that the Ca-Na pyroxenes occur within a restricted P-T space between the prehnite-pumpellyite and pumpellyite-actinolite facies. -J.A.Z.
