Paper Structure
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 will be on the spectacular New Zealand geology. We will examine metamorphic reactions that take place in the shallow crust (eg zeolite facies) through to deep crust (eg eclogite facies), as well as the largest metamorphic complex on Earth: the upper mantle. Metamorphic facies classification and basic geothermobarometry are explained. For metamorphic mineralisation, we will examine the formation of mesothermal gold deposits, massive sulphide deposits, skarns and diamond occurrences. The paper is structured so that the lectures and labs are integrated.

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 GEOL374 are set and graded differently to GEOL274 to reflect greater background knowledge and higher expectations of students taking the paper at 300-level.
