The two classifications of metamorphic rock are foliated and non-foliated:
1. Foliated metamorphic rock such as gneiss display banding and regrouping of its mineral constituents as a result of enormous pressures and heat. The banding forms perpendicularly to the direction of pressure. The pressure is usually related to tectonic plate collisions. Schist is another type of foliated rock that exhibits thin layering of micaceous minerals, once again due to pressure and heat. The difference between these two types of foliated rock lies in the rock from which they were derived.
2. Non-foliated metamorphic rock such as quartzite and marble do not display the banding or layering that are present in foliated rocks. This is because their parent rock was usually sedimentary and more pure in mineral composition than the parent rocks of foliated rocks.
Metamorphic rock can also be classified as regional (from broad processes such as plate tectonics) or contact (from proximity to an invading heat source).
