Course Aims

To develop students' understanding of structural and metamorphic processes and the response of rocks to changing P-T conditions and deformation. To develop skill sets to independently interpret the geometries, kinematics, mechanics and mechanisms of deformed, fractured and faulted rocks in the field. Residential field class focuses on advanced field mapping techniques and their application to problems, such as the location of resources and rock failure.

Intended Learning Outcomes of Course

By the end of this course students will be able to:

 

■ Identify parent rock types, estimate metamorphic conditions and assess the cause of metamorphism for a variety of metamorphic rocks using detailed hand specimen and thin section descriptions.

■ Interpret rock textures to assess deformation mechanisms, shear sense indicators and mineral reactions 

■ Construct metamorphic phase diagrams and explain their significance to petrology.

■ Explain the role of fluids in metamorphic reactions and their influence on deformation mechanisms.

■ Critically discuss the structural and metamorphic characteristics of a range of tectonic environments, the determination of the ages of such tectono-thermal events, and associated variations in metamorphic grade.

■ Critically apply a wide range of skills that enable the use of microstructures in the field to quantify tectono-metamorphic relations and faulting during mapping.

■ Construct and critically evaluate from geological maps through balancing to solve practical problems, such as predicting the location of resources.

■ Discuss three-dimensional stress geometries and apply failure criteria to critically evaluate the stability of slopes and rock surfaces.

■ Independently map and critically interpret tectono-metamorphic terrains in the field.

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.
