Course overview
This course examines the origin and evolution of igneous and metamorphic rocks. It focuses on both descriptive work and theoretical background related to rock formation and development. Igneous Geology: This section examines the controls on the generation and differentiation of silicate melts within the earth and the contribution these processes have made to the composition of the crust and mantle through time. It also uses the basis of elemental and isotope geochemistry to understand these processes. We examine case studies of magma generation in key tectonic settings on the earth through time. Metamorphic Geology: This examines the nature and change of sub-solidus mineral assemblages and textures in rocks. This information provides a sound basis with which to examine orogenic processes.
Course learning outcomes
- Demonstrate proficiency in common practical skills in igneous and metamorphic geology
- Understand how the occurrence and character of different igneous and metamorphic rock suites is governed by and reflects the Earth's tectonic processes;
- Explain how magma is generated in the Earth's mantle and how magma typically evolves
- Be able to organise, plot and evaluate the petrogenesis of igneous rock suites using elemental data
- Understand different geochronological and isotope geochemical techniques and their applications to igneous andmetamorphic processes
- Explain how absolute pressure-temperature information is extracted from rock using thermodynamic expressions.
