Gneiss is a high grade metamorphic rock, the product of various rock types being exposed to intense pressures and heat under the surface of the Earth. Orthogneiss is a gneiss whose parent rock was igneous, and paragneiss is a gneiss whose parent rock was sedimentary.

The original parent rock (or protolith) of mica schist is shale. Phyllite could also be considered the parent rock as mica schist is a more highly metamorphosed phyllite.

What is the location of schist?
Schist is a form of metamorphic rock in which a sedimentary rock has been subjected to heat and pressure. These change agents will alter the structure of the rock, and will allow / cause the minerals in the rock to change and aggregate. Schist is a very common rock type, but does need the parent rock to have undergone metamorphism.

muscovite
