Exploration of processes involved in the generation and evolution of igneous rocks and the techniques used to study them and their associated volcanic hazards. The course is taught through a combination of lectures, laboratories, and both residential and day field classes.
Four classes per week for 3 weeks (2 hr lecture and 1 hr lab per class). Local 1 day field class. 8-day residential overseas field class.
Requirements of Entry
Normally completion of all credit-bearing courses from Earth Science Level 2 at an average Grade C3 or better, achieving at least a Grade of D3 in each individual course and attendance at the residential field class.

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.
