Definition of metamorphism. : a change in the constitution of rock; specifically : a pronounced change effected by pressure, heat, and water that results in a more compact and more highly crystalline condition.
There are four types of metamorphism 1.contact metamorphism: results from rocks being adjacent to igneous intrusions. Characterized by high temperatures and active chemical fluids (divergent plate boundary) 2. dynamic metamorphism: results from directed pressure along faults.here are four types of metamorphism 1.contact metamorphism: results from rocks being adjacent to igneous intrusions.
