Contact and regional metamorphism. Metamorphic facies, geothermal gradients and relationships with tectonic settings. Examples of study of igneous, metamorphic and mantle rocks at the outcrop scale.
The main micro-structures of mantle, igneous and metamorphic rocks, and their petrogenetic implications. How to write a petrographic report. Study of metamorphic rocks at the hand sample scale. Use of the polarised-light optical microscope to study thin sections of rocks. Micro-structural studies of mantle, igneous and metamorphic rocks.
