Metamorphism occurs because some minerals are stable only under certain conditions of pressure and temperature. When pressure and temperature change, chemical reactions occur to cause the minerals in the rock to change to an assemblage that is stable at the new pressure and temperature conditions.
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.Characterized by strong directed pressure and increased temperature due to depth.esults in foliated rocks (convergent plate boundary) Metamorphic rocks are classified basesd on their texture and composition. The different textures and compositions provide information about the conditions of metamorphism and the protolith (parent rock).
