Regional metamorphism occurs over broad areas when rocks undergo deformation due to pressure and associated heat from overlaying rocks or other tectonic forces. Contact metamorphism occurs when rocks are altered due to contact with an igneous intrusion. Intrusive metamorphism occurs when magma intrudes into and alters surrounding rocks. Extrusive metamorphism occurs when rocks are altered by volcanic activity.
