Metamorphic Reactions, Isograds, and Reaction Mechanisms

Stephen Nelson, Deparment of Geology

These lecture notes cover types of metamorphic reactions. Topics discussed include univariant and divariant reactions, mineral compatibility diagrams (AFM ternary), metamorphic reaction mechanisms, and metamorphic field gradients. The notes contain many ternary diagrams and graphs illustrating the relationship between pressure, temperature, and mineral composition. This resource is part of the Teaching Petrology collection.

Part of the Cutting Edge collection. The NAGT/DLESE On the Cutting Edge project helps geoscience faculty stay up-to-date with both geoscience research and teaching methods.
