| Summary | Igneous Petrology
An outline of modern concepts of upper mantle composition and partial melting, and the evolution of magmas. The course presents a broad review of igneous rocks, emphasising their phase relations, tectonic associations, and petrogenesis. Please bring an optical properties book (e.g. Deer, Howie & Zussman) to all practicals.
Metamorphic Petrology
An introduction to the principles that govern mineralogical and textural change in rocks in response to imposed conditions of pressure, temperature and other variables. Diagrammatic representation of metamorphic mineral assemblages and reactions. The nature of occurrence and variety of mineral assemblages found in common metamorphosed rocks, especially those of basaltic and pelitic composition, and their dependence on bulk rock chemical composition and on the P-T conditions of metamorphism. A review of metamorphic facies and facies series and their distribution, and of thermal and tectonic controls of metamorphism. |

Learning Outcomes
On completion of this course, the student will be able to:
- This course presents a broad review of igneous rocks, emphasising their tectonic associations, interrelationships and petrogenesis as well as an introduction to the principles that govern mineralogical mineral assemblages and reactions in metamorphic rocks.
- After successful completion of this course you will have an integrated understanding of the range, composition and petrogenesis of the major igneous and metamorphic rock groups and will be able to identify them in thin section and deduce their tectonic association and mode of origin.
- You will review metamorphic facies, facies series and their distribution, as well as the thermal and tectonic controls on metamorphism.
- You will become familiar with the key skills used to aid the interpretation of metamorphic rocks: AKF, AFM diagrams and Thompson projections (for pelites) and petrogenetic grids and you will learn how to interpret these.
