I. Metamorphic Rock Metamorphic rocks form from intense heat and pressure. These rocks start out as some other type of rock, but have been substantially changed from their original form. How Do Metamorphic Rocks Form? II. Origins of Metamorphic Rock A. Contact Metamorphism Rock undergoes metamorphism when it comes in contact with magma or is heated by nearby magma. II. Origins of Metamorphic Rock B. Regional Metamorphism Pressure builds up in rock that is buried deep below rock formations or when large pieces of rock collide. III. Textures of Metamorphic Rock A. Foliated: texture of metamorphic rock in which the mineral grains are arranged in planes or bands. III. Textures of Metamorphic Rock B. Nonfoliated: The texture of metamorphic rock in which the mineral grains are not arranged in planes or bands.
