Metamorphic Reactions, Isograds, and Reaction Mechanisms

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.
