ESC3421 - Volcanology and igneous petrology

Leader(s): Dr Ian Nicholls

Offered

Clayton First semester 2009 (Day)

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.

Objectives

On completion of this unit, the student will have a knowledge of: the nature of melting processes within the Earth's interior and the way magmas move toward the surface, fill magma chambers, undergo crystallization and erupt; the physical processes which underlie volcanic activity, involving a range of magma types; the field occurrence and mineralogical/chemical nature of a range of products of magmatic activity, with emphasis on volcanic products; the distinctive geochemical features of volcanic rocks in the various global tectonic environments, and the significance of these features in terms of magma sources and evolution processes.
