Undergraduate Course: Igneous and Metamorphic Petrology (EASC09008)
|School||School of Geosciences
||College||College of Science and Engineering
|Credit level (Normal year taken)||SCQF Level 9 (Year 3 Undergraduate)
||Availability||Available to all students
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.
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.
LP1 Nomenclature, classification and distribution of igneous rocks.
LP2 Composition of the Earth's mantle; ultrabasic and ultramafic rocks.
LP3 Basalts; genesis and compositional range. Formation of oceanic crust.
LP4 Subduction-related magmatism. Formation of continental crust.
LP5 Origin of granites.
LP6 Parameters of metamorphism. Mineral assemblages, phases and components. The mineralogical phase rule. Composition-paragenesis diagrams.
LP7 AKF, AFM diagrams and Thompson projections for pelites. Metamorphic reactions. Medium pressure regionally metamorphosed pelites - reactions and isograds. Barrow's Zones revisited. Construction of Thompson projections.
LP8 Low pressure regionally metamorphosed pelites - reactions and isograds. Migmatites and partial melting. Pelite facies series. Petrography of pelitic mineral assemblages.
LP9 Petrogenetic grids. Geothermometry and geobarometry. Introduction to common mineral assemblages in metabasic rocks. Petrography of contact metamorphic pelites - the Ballachulish Aureole.
LP10 Mafic mineral assemblages - projections, reactions and facies series. Metamorphic facies and their distribution; introduction to extreme P-T facies, P-T-time paths, and thermal and tectonic settings of metamorphism. Petrography of mafic rocks.

Course Delivery Information
|Not being delivered|
On completion of this course, the student will be able to:
- You will know and understand the tectonic associations, interrelationships and petrogenesis of igneous rocks, and understand the processes by which the Earth's oceanic and continental crust are
- You will know what the Earth's mantle is made of and understand the various strands of petrology and geochemistry that lead to this knowledge.
- You will know and understand the principles that govern mineralogical assemblages and reactions in metamorphic rocks: metamorphic facies, facies series and their distribution, as well as he thermal and tectonic controls on metamorphism.
- You will be 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 have
- You will be able to identify the major igneous and metamorphic rock groups in thin section and deduce their tectonic associations.
