any of a class of crystalline metamorphic rocks whose constituent mineral grains have a more or less parallel or foliated arrangement.
any metamorphic rock that can be split into thin layers because its micaceous minerals have become aligned in thin parallel bands
A highly foliated, medium-grained metamorphic rock that splits easily into flakes or slabs along well-defined planes of mica. The mineral composition of schist is varied and is often reflected in the name given to the rock. For example, a schist that contains garnet is called a garnet schist. A schist containing chlorite is called a chlorite schist.
