Module Learning Aims:
To gain a broad understanding of magma generation in the various tectonic environments and assess the production, differentiation and eruptive behaviour of magmas. The students also learn to appreciate the role of magmatic rocks in regulating the Earth's climate and the use of tephra in Earth surface studies. They will become familiar with advanced analysis of geochemical data and develop an appreciation of the importance of experimental studies.
Module Content:
The module explores the key igneous rocks in the various tectonic settings and by use of petrology and geochemistry, investigates magma source evolution. The module will also study the anatomy of igneous centres and interrogate the history of large igneous provinces and their role in regulating long-term atmospheric composition. Finally, the module will focus on the opportunities that exist to use tephra for studying the relatively recent surface history of the Earth. Throughout the module, a combination of petrography, petrology, geochemistry, and radiogenic isotopes will be applied to extract the finer details from igneous rocks.
Learning Outcomes:
On successful completion of this module students should be able to:
• use petrology, major and trace element chemistry and radiogenic isotope data from igneous rocks to interpret them in a plate-tectonic framework, describe in details the use of tephra in Earth surface studies
