- GLOSSARY OF VOLCANIC TERMS
In the strictest sense, rocks that have formed in the solid state in response to pronounced changes in temperature and/or pressure without any change in the bulk chemical composition of the rock. Metamorphic processes are generally confined to regions within the earth below the zones of weathering, cementation, and diagenesis.
