Description

The first section of this course deals with the fundamentals of geochemistry and phase petrology. The second section provides a detailed analysis of the major tectonic and petrological processes involved in the generation of the major igneous rock groups on the planet (basalts, andesites, granites). An overarching theme examines the changes in continental building processes through time, using the Australian continent as the example.

    Learning outcomes

    On successful completion of the course students will be able to:

    1. Describe and apply the concepts and scientific principles behind the major themes in petrology and be able to communicate and explain them effectively;

    2. Collect and collate observational and analytical data and use the information to critically evaluate existing/competing models;

    3. Solve qualitative problems using appropriate mathematical and computing techniques;

    4. Present observations and interpretations by detailed report format or via oral presentation;

    5. Adapt to (advice/evidence/feedback) received from a range or sources.
