EAE3521 - Earth petrology, lisotope geology and geochronology - 2019

This unit investigates the igneous and metamorphic petrology and geochemistry of the Earth's mantle and crust, and provides an introduction to the geology of meteorites and planets via these principles. Igneous petrology and geochemistry deals with the formation, migration, fractionation and emplacement of magmas in various settings in the Earth, asteroids and planets. Metamorphic petrology deals with the formation of metamorphic rocks, and the use of these rocks in investigating the tectonic evolution of the Earth's crust, and of the interior of asteroids.

On completion of this unit students will be able to:

1. Identify the various types of igneous and metamorphic rocks in hand specimen and in natural field outcrops;
2. Evaluate the distinctive geochemical and petrographic features of igneous and metamorphic rocks, including meteorites;
3. Evaluate and constrain the geochemical sources and evolution of magmas within the silicate earth and other planets, and identify their dominant controlling processes;
4. Understand the processes that lead to the formation of metamorphic rocks in the Earth's crust, and within asteroids;
5. Understand how isotopes are used in geosciences and apply them in interpreting magmatic and metamorphic processes;
6. Understand the links between plate tectonics, magma genesis and regional metamorphism, and apply that understanding to interpret the evolution of different tectonic domains.
