I. Metamorphism Diagram

1) Contact metamorphism ~ When rock undergoes metamorphism due to contact with magma or lava.

2) Regional metamorphism ~ When rock undergoes metamorphism do to tremendous pressure (deeply buried, plate collision zones).

II. Metamorphic Processes

1) Foliated: Rocks that have mineral grains that are aligned by pressure

2) Non-foliated: Rocks that lack mineral grain alignment
