Contact metamorphism occurs when rocks are exposed to the high temperature and pressure associated with intruding magma. This type of metamorphism is localized and occurs in the immediate vicinity of the magma body. Regional metamorphism, on the other hand, occurs over larger areas and is often associated with tectonic activity or mountain building. Intrusive metamorphism and extrusive metamorphism are not specific processes, but refer to metamorphism that occurs within or outside of the Earth's crust, respectively. Clastic metamorphism refers to metamorphism that occurs as a result of the compaction and cementation of sedimentary rocks.
