Course Aims

The aim of this course is to develop students' understanding of fundamental processes in igneous geology. This will include: determining mantle sources and tectonic settings; magma genesis and evolution; the geochronology of rocks and the rates of igneous processes; and volcanic hazards and their monitoring techniques. Aspects of petrogenesis, physical volcanology and hazards will be evaluated in the field.

Intended Learning Outcomes of Course

By the end of this course students will be able to:

■ Outline and discuss the petrogenesis of mantle- and crustally-derived magmas using a variety of geochemical datasets, including radiogenic and stable isotopes.

■ Model petrogenetic processes using appropriate software.

■ Critically evaluate dating methodologies for igneous rocks.

■ Describe and interpret volcanic rocks in the field and propose eruption histories and modes of deposition or emplacement.

■ Distinguish a variety of volcanic and volcano-associated hazards in the field, and explain how hazards may be monitored at active volcanoes using remote sensing techniques.

■ Use geological maps to evaluate volcanic hazards and the emplacement and distribution of igneous bodies.

■ Explain how igneous rocks and minerals can be used economically.

Minimum Requirement for Award of Credits

Students must submit at least 75% by weight of the components (including examinations) of the course's summative assessment.
