Slate Slate is a metamorphic rock. Metamorphic rocks are formed when sedimentary or igneous rocks are exposed to conditions of very high pressure or temperature, or are exposed to large amounts of very hot water.
The following is a list of rock types recognized by petrologists.There is no agreed number of specific types of rocks. Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe rock types.

Metamorphic rock: Metamorphic rock, any rock that results from the alteration of preexisting rocks in response to changing conditions, such as variations in temperature, pressure, and mechanical stress, and the addition or subtraction of chemical components.

Any rock (igneous, sedimentary, or metamorphic) can become a metamorphic rock. If rocks are buried deep in the Earth at high temperatures and pressures, they form new minerals and textures all without melting.
Gneiss is a foliated metamorphic rock in which the coarse mineral grains have been arranged into a banded structure.
Metamorphic rocks are classified by texture and by mineral composition. Foliated metamorphic rocks. If a rock is foliated, its name is determined by the type o
