Module Overview
Aims and Objectives
Learning Outcomes
Learning Outcomes
Having successfully completed this module you will be able to:
- Identify the common rock forming minerals of igneous and metamorphic rocks in both hand specimen and thin-section.
- 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.
- Assign a name to an igneous or metamorphic rock on the basis of its mineralogical and textural characteristics, and appreciate the environment(s) of formation.
- Practical experience of rock and mineral identification in hand specimen and in thin-section using a transmitted light microscope.
- 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.
- 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.
Syllabus
Methods: Coverage of igneous 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. Introduction to the concept of metamorphic facies as a means of defining P-T conditions; quantitative geothermometry/ geobarometry; evaluating the role of bulk rock chemistry, fluid chemistry and P-T conditions in controlling metamorphic reactions; interpretation of textures and microstructures of metamorphic rocks. Practicals: Hand specimen and thin-section description of various igneous and metamorphic rocks. Evaluation of P-T condition of metamorphism based on phase assemblages.
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
Assessment Method Theory examination (50%): A 2-hour written examination comprising two sections - one on igneous petrology and the other on metamorphic petrology. A total of 3 questions must be answered, with at least 1 from each section. Tests learning outcomes 1-2. Igneous coursework (25%): Three pieces of coursework to be handed in at the end of practical classes (10% total) and a practical examination of petrological techniques in igneous systems and knowledge of igneous terminology and processes (15% total). Tests Learning Outcomes 1-3. Metamorphic coursework (25%): Two pieces of coursework to be handed in at the end of practical classes and a practical examination. Tests Learning Outcomes 1-3.
