This 37-slide PowerPoint presentation covers thermodynamics in metamorphic rocks. Gas phases are described in terms of gas pressure-volume relationships in light of the ideal gas law. T-X relationships and compositional variations are considered in describing qualitative solutions to dehydration reactions. The presentation covers geothermobarometry in detail, using P-T diagrams to illustrate the concepts. 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.
