Synopsis

Physical volcanology: will address volcanic eruption styles and processes, and the variety and characteristics of eruption products. Igneous petrology: will include material on the petrology and geochemistry of the Earth's mantle and crust, their melting to generate silicate magmas and the emplacement of these magmas in and on the crust; also the basics of trace element and isotope geochemistry applied to the understanding of these processes.

Outcomes

On completion of this unit students will be able to:

  1. Recognise the physical processes which underlie volcanic activity, involving a range of magma types;

  1. Identify the various types of volcanic and igneous rocks in hand specimen and their occurrence, context with other rock units, and distinctive features in natural field outcrops;

  1. Analyse the distinctive geochemical and petrographic features of volcanic and intrusive igneous rocks in the various global tectonic environments;

  1. Further their knowledge of melting and magmatic crystallisation processes within the Earth's interior and the way magmas move toward the Earth's surface;

  1. Evaluate and constrain the geochemical sources and evolution of magmas within the silicate earth and identify their dominant controlling processes;

  1. Understand how isotopes are used in geochronology (dating of Earth materials) and their application in identifying magmatic processes and their petrogenesis.

Assessment

Practical work: 30%
Fieldwork: 20%
Examination (3 Hours): 50%

Students must pass the theory examination to achieve an overall pass grade. Students who do not pass the theory examination will receive a mark of 45% unless their aggregate mark is lower, in which case that mark will be recorded.
