Concepts and controls of metamorphism; chemical equilibrium and graphical portrayal of mineral assemblages; metamorphic grade and metamorphic facies; relationship between metamorphism and tectonics; New Zealand metamorphic rocks; metamorphic mineralisation.
This paper covers a spectrum of metamorphic types, including contact, regional and some of the metamorphic extremes, such as ultra-high-pressure and ultra-high-temperature. All types are discussed with reference to examples from around the world, although the focus is on the spectacular New Zealand geology. We will examine metamorphic reactions that take place in the shallow crust (e.g., in the zeolite facies) through to those that occur in the deep crust (e.g. in the eclogite facies), as well as those that occur in the largest metamorphic complex on Earth: the mantle. For metamorphic mineralisation, we will examine the formation of mesothermal gold deposits, massive sulphide deposits, skarns and diamond occurrences.

- Paper Structure
The paper is structured so that the lectures and labs are integrated.
The first two weeks are on contact metamorphism and skarns. This is followed by a section on regional metamorphism and then fault zone deformation and recrystallisation. The course progresses into geothermobarometry, and then into high pressure metamorphism in the crust and mantle.
Assessment: 40 % internal component, made up of a take home assignment and a practical test, with a 60 % final written exam. Assessments for GEOL 374 are set and graded differently to GEOL 274 to reflect greater background knowledge and higher expectations of students taking the paper at 300-level.
- Teaching Arrangements
- Two lectures and one 3-hour laboratory per week.
Fieldwork: 1 day field excursion to the Haast Schist occurring south of Dunedin.
Textbooks are not required for this paper.
