Graphite schist protolith
WebPolith: The protolith of schists can be igneous (e.g. basalt, volcanic tuff) or sedimentary (clay, mud). Notes: Garnet mica schist is a variation of mica schist, a metamorphic rock formed by medium grade metamorphism which is usually a combination of both heat and pressure applied to the original rock, often a clay, mud or shale. 5.
