Objectives

Overall objective: To improve understanding of the nature of crystalline rocks and the processes by which they form, and to provide a basic training in their identification.

Specific Learning Outcomes:

At the end of the module, you should be able to:
- understand the processes by which magma is generated within the Earth;
- use simple phase diagrams to understand partial melting and fractional crystallisation; investigate the origins of layered igneous intrusions in the context of crystal settling models;
- understand the controls on magmatic differentiation by fractional crystallisation and the use of Harker variation diagrams to illustrate this;
- use both optical microscopy and hand specimen identification to study a range of magmatic and mantle rock types;
- understand the various parameters which influence the rheology of magmas;
- describe the textures of metamorphic rocks and deduce relationships to metamorphic reactions and deformation;
- analyse mineral assemblages in term of metamorphic reactions and the phase rule;
- describe and interpret mineral assemblages of pelitic sediments;
- describe and interpret mineral assemblages of blueschists and eclogites in relation to metamorphic facies;
- describe and interpret mineral assemblages of metamorphosed impure limestones and their relationship to metamorphic fluids;
- appreciate the range of physical conditions that lead to magma generation, modification and emplacement and metamorphism, their relationship to tectonic setting and how rocks can be used to infer past tectonic settings.

The module is both practical and theoretical; therefore students should attend all taught components. At minimum, practical classes will be subject to attendance monitoring.

Syllabus

Igneous Petrology: Melting processes in the Earth. Phase diagrams. Calc-alkaline and tholeiitic trends. Silicic magmatism, Processes in magma chambers and their crysallisation history. Physical properties of magmas. Magmatism in extensional settings (e.g. midocean ridges) and in collision zones (volcanic arcs).

Metamorphic Petrology: Metamorphic rocks as records of physical and chemical processes; petrogenetic grids, phase diagrams and projections. Progressive metamorphism of major rock types, metamorphic facies. Metamorphic processes and the role of fluids. Geodynamic settings of metamorphism and their relationship to magmatism and tectonic activity.
