A medium-grained metamorphic rock generally derived from fine-grained sedimentary rock like shale, showing pronounced schistosity: mineral grains visible with a hand lens, oriented so the rock splits into thin flakes or plates. That texture reflects a high content of platy minerals such as mica, talc, chlorite or graphite, and the rock typically forms during the regional metamorphism that accompanies mountain building.
