Methods: Coverage of igneous and metamorphic rock classification (mineralogical/geochemical); the use of geochemistry in petrogenetic concepts; an introduction to phase petrology and the concepts of partial melting and fractional crystallisation; a brief review of the main igneous rock spectrum and their tectonic setting.
Covering the concept of metamorphic facies as a means of defining P-T conditions and how mineral assemblages can be used to recreate the metamorphic history of a rock.
Practicals: Hand specimen and thin-section description of various igneous and metamorphic rocks.
Learning and Teaching
Teaching and learning methods
Formal lectures: will provide an introduction to the theory underlying metamorphism, phase petrology, igneous rock classification and the use of geochemistry in petrogenetic concepts.
Practical classes & demonstrations: will exemplify the theory and allow you to develop skills in hand specimen and thin section description of various igneous and metamorphic rocks. Practical classes are fully interactive affording hands-on experience of using geological equipment under laboratory conditions. Practical manuals are an integral part of the course.
A wide range of support can be provided for those students who have further or specific learning and teaching needs.
Assessment
Assessment strategy
Exam (40%): digital exam answering theory questions about igneous and metamorphic petrology. Questions will test understanding and skills as much as knowledge, through the use of photos and diagrams of petrological structures, textures and processes.
Igneous/volcanic practical examination (30%): a practical examination of petrological techniques in igneous systems – based on thin section description of multiple igneous rocks.
Metamorphic practical examination (30%): a practical examination of petrological techniques in metamorphic systems – based on thin section description of multiple metamorphic rocks.
