Metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). The change occurs primarily due to heat, pressure, and the introduction of chemically active fluids.etamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change).

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.
