Metamorphism and Formation of Igneous Rocks PROCESSES INVOLVED IN METAMORPHISM  Types of metamorphism  The process of metamorphism is controlled by four factors – temperature, pressure, chemically active fluids, and time. These factors determine the degree of metamorphism the protolith will experience. Effects of the 4 factors on rock formation II.
