Types of Metamorphism 1. Regional Metamorphism 2. Contact Metamorphism 3. Seafloor Metamorphism 4. Burial Metamorphism 5. High Pressure Metamorphism 6. Shock Metamorphism Review We classify metamorphic rocks as either: Foliated or Non-foliated A foliated metamorphic rock has a direction to it due an alignment of minerals.
