GEOS3330Tectonics

Course handbook

Description

This course examines the geological processes of deformation and metamorphism. The practical component of this course focuses on introducing the key concepts behind metamorphic phase equilibria and mineral textural relationships. The course will provide students with the knowledge required to link metamorphism to structural studies (assumed knowledge from GEOS2190). This will result in an enhanced understanding of tectonic processes responsible for reworking continental regions. The field component provides an advanced field course in metamorphic and structural analysis and interpretation of complex, multiply deformed geological terrains. Detailed fieldwork will be augmented with microstructural analysis using thin sections, to determine a pressure-temperature-time (P-T-t) history of the region, so that a tectonic setting can be evaluated.

NOTE: Field study will be scheduled prior to the formal commencement of semester.

Learning outcomes

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

1. Observe and characterise metamorphic mineral assemblages.

2. Develop an understanding of metamorphic phase equilibria.

3. Develop a high degree of mapping skills.

4. Develop skills for microstructural interpretation.

5. Learn to present geological information in the form of a scientific report.

6. Develop research and communication skills and be able to present written reports.

Content

Lecture ComponentPrinciples of metamorphism.Metamorphic rocks and facies..Metamorphic mineral textures and microstructure.Metamorphic phase equilibria.P-T paths and tectonic environments.Multi deformation - structural inheritanceField Component:8 days of high-level field mapping in a complex, multi deformed and metamorphosed geological environment. A major aim of the exercise is to unravel the geological and tectonic evolution of the region and write up as a report.
