Two Component Phase Diagrams

Stephen Nelson, Department of Geology

This site contains lecture notes that are part of a petrology class taught at Tulane University. This section includes a discussion of systems, phases, components, the phase rule, two component eutectic systems, incongruent melting, rocks of varying composition and fractional crystallization, solid solution and exsolution. The lecture notes contain text, definitions and annotated phase diagrams. 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.
