Compulsory 6-day excursion before the start of semester 1 is assessed by field tests and a mapping exercise. Students are expected to contribute towards excursion accommodation costs.
This unit provides a systematic description and quantitative interpretation of magmatic rocks within a plate tectonic framework. Topics covered in the first part of the Unit introduce the necessary tools and techniques. The remainder of the Unit applies these methods to a survey of the major igneous rock associations on Earth. Lectures and tutorial 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 rocks. 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 4th year (Honours).

Please check that your computer meets the minimum System Requirements if you are attending via Distance/Off-Campus.
Units are offered in attending mode unless otherwise indicated (that is attendance is required at the campus identified). A unit identified as offered by distance, that is there is no requirement for attendance, is identified with a nominal enrolment campus. A unit offered to both attending students and by distance from the same campus is identified as having both modes of study.

* The Final WW Date is the final date from which you can withdraw from the unit without academic penalty, however you will still incur a financial liability (refer to How do I withdraw from a unit? for more information).
Unit census dates currently displaying for 2024 are indicative and subject to change. Finalised census dates for 2024 will be available from the 1st October 2023. Note census date cutoff is 11.59pm AEST (AEDT during October to March).
- Identify minerology and texture of magmatic rocks using a petrographic microscope in a safe and correct manner.
- Explain geochemical and isotopic data using basic petrological tools to constrain evolution and petrogenesis of igneous rocks.
- Interpret the key processes that control the evolution and emplacement of igneous rocks, including partial melting, fractional crystallisation, magma mixing and crustal contamination.
- Interpret the major magmatic rock associations, their mineralogy, and chemical compositions to link them to specific tectonic settings.
