Learning Outcomes
Learning Outcomes
Having successfully completed this module you will be able to:
- Ability to interpret phase diagrams relevant to igneous systems and petrogenic grids relevant to metamorphic systems on the basis of mineral assemblages recorded in the rock.
- Identify the common rock forming minerals of igneous and metamorphic rocks in both hand specimen and thin-section (using a transmitted light microscope) and classify the rock.
- Assess the processes and conditions that generate the variety of metamorphic rocks .
- Identify key textural/micro structural features of igneous and metamorphic rocks and appreciate the significance of such features with regard to geological processes that have operated.
- Ability to make detailed and annotated petrographic sketches from thin-section observation and to summarise the salient features and relate the chemistry of the system and environment of formation.
- Assess the magmatic processes that generate the variety of igneous rocks and compositions.
Syllabus
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 week will be spent in the field training in advanced structural techniques.
A wide range of support can be provided for those students who have further or specific learning and teaching needs.

Assessment
Assessment strategy
Theory examination (40%): A 2 hour written examination on igneous and metamorphic petrology, volcanic processes and geologic deformation. Two questions from 4 must be answered (one igneous and one metamorphic).
Igneous/volcanic practical examination (30%) in two parts: 1), a practical examination of petrological techniques in igneous systems – based on a full thin section description of an igneous rock (20%) and 2), a quiz testing knowledge of igneous terminology and processes (10%).
Metamorphic practical examination (30%): thin section description of multiple metamorphic rocks.
