This unit provides a systematic description and quantitative interpretation of magmatic rocks within a plate tectonic framework. Lectures cover an introduction to igneous petrology and geochemistry, and key aspects of the mineralogy, textures, classification and origin of the main types of igneous rocks. Laboratory work includes practical exercises aimed at mastering tools and techniques used in igneous petrology and geochemistry, tutorials on optical mineralogy, and hand sample and microscope investigations of igneous and rocks. Topics covered in the first part of the course introduce the necessary tools and techniques. The remainder of the course will apply these methods to a survey of the major igneous rock associations on Earth. The unit also involves a 6-day field excursion that precedes the beginning of semester 1. The field trip examines the geology of western Tasmania and provides practical experience in mapping and interpreting complex outcrops. Daily field tests and a mapping exercise are included in the course assessment.

This unit is designed to bring students' knowledge of these topics up to graduate level, adequate for school teaching and for continuation into 4^thyear (honours), which is now recognised as the minimum professional level of training. This course is required for undertaking Honours in General Geology, Economic Geology, Environmental Geology and Marine Geoscience, and Desirable for Honours in  Geophysics.
