In geology, an intrusion is a rock that has been frozen into a crystal from the melt in the magma under the Earth surface. Magma is frozen below the ground before they reach the surface of the earth called pluton, the name of Pluto, the Roman god of the world underground. Rock of this type are also referred to as the frozen rock plutonik or frozen rock intrusif. He was opposed to the rock ekstrusif. Stone encircle the pluton called country rock.
