WebbGeneral terms used to describe the chemical composition of both the protolith and the resulting metamorphic rock are: Pelitic Alumina rich rocks, usually shales or mudstones. These start out originally with clay minerals and as a result of metamorphism, Alumina rich minerals like micas, chlorite, garnet, kyanite, sillimanite and andalusite form. WebbA foliated metamorphic rock, schist comprises flat grains of mineral that are quite large. They often form on the continental side of a convergent plate boundary. This is where …
WebbMafic Schist - foliated or nonfoliated rock of any grain size composed predominately of mafic minerals (particularly chlorite, epidote, amphibole, pyroxene) and plagioclase.
