WebThe three types of metamorphism are Contact, Regional, and Dynamic metamorphism. Contact Metamorphism occurs when magma comes in contact with an already existing … WebLow pressure is the realm of contact metamorphism. Figure 14.35 is a map of a contact aureole around the Devonian Onawa Pluton, a granodiorite body in central Maine. The pluton, an elliptical granodiorite body, intruded into a slate country rock. The slate was a product of earlier regional metamorphism that occurred before the Onawa pluton formed.
