Types of Metamorphism - Tulane University

Low-grade metamorphism takes place at temperatures between about 200 to 320 o C, and relatively low pressure. Low grade metamorphic rocks are generally characterized by an abundance of hydrous minerals. With increasing grade of metamorphism, the hydrous minerals begin to react with other minerals and/or break down to less hydrous minerals.
