Schist, megascopically crystalline rock that has a highly developed schistosity, or tendency to split into layers.Banding (foliation) is typically poorly developed or absent. Most schists are composed largely of platy minerals such as muscovite, chlorite, talc, sericite, biotite, and graphite; feldspar and quartz are much less abundant in schist than in gneiss.
