Metamorphic Geology


Course Objective

Gain a sufficient understanding of the theoretical basis of metamorphism
(i.e. chemical thermodynamics) for the calculation of phase equilibria
in open and closed systems for common non-metamorphic protoliths. This
approach will be the basis for critically assessing PTt paths and; hence
deriving the implications for geodynamic processes preserved in
metamorphic rocks. Learning the basics of phase equilibrium modelling
using Thermocalc, TheriakDomino and/or Perple_X. Expand skills in
optical microscopy as applied to metamorphic rocks.

Course Content

Metamorphic phase equilibria, their variance and calculation;
theoretical (chemographic) analysis of assemblages and reactions;
element distribution between minerals; recognition of stable assemblages
and of reactions in rocks. Role of fluid phases. Metamorphism of pelitic
sediments, carbonate rocks and mafic (igneous) rocks.
Geothermobarometry and PT-paths. Diffusion mechanisms and the concept of
closure temperature as pertaining to geochronology of metamorphic
processes. Critical assessment of PTt- data. Relation between PTt- paths
and geodynamic processes.

Teaching Methods

Lectures with associated class- and homework and tutorial seminars.
Three 15- to 30-minute written tests to help keep track of your
progress. Practicals: microscopy, chemographic analysis, calculation of
phase equilibria, geothermobarometric calculations, online assignment
closure temperature. Individual poster presentation with an accompanying
'elevator pitch' on a selected subject.
Contact hours: 12 half-day classes made up of lectures and practical
exercises. One half day class of student presentations and one written
examination (2.5 hours).

Method of Assessment

All practical assignments must be completed; together they make up 30%
of the final mark. The three written tests together count for 5% of the
final mark. The poster and its presentation each make up 12.5% of the
mark whilst the remaining 40% is for the written examination.


Textbook: Winter (2010) An introduction to igneous and metamorphic
petrology, 2nd ed., Prentice Hall.
Some chapters from Bucher & Grapes (2011) Petrogenesis of metamorphic
rocks, 8th ed., Springer, which may be copied from the teacher or the
Papers to be used as background reading for lectures will be listed on
the Canvas-site at the start of the course. The list of papers that
serve as topics for the presentations is made available in the first
week of the course.

Target Audience

First year MSc Earth Sciences students in the geology & Geochemistry
track; second year students are very welcome to take this course as
well. Together with Magmatic Processes this course forms a comprehensive
preparation for research and master thesis projects in the hard rock
geology / petrology / geochemistry subdisciplines.

Additional Information

This course fits well within the lithosphere orientation of Geology &
Geochemistry, together with courses like Magmatic Processes, Advanced
Inorganic Geochemistry and Advanced Geochronology. It builds on Mantle
Properties and Orogenesis, as well as courses in petrology, chemistry
and tectonics at the BSc level.
