Module Learning Aims:

This module aims to provide an advanced understanding in radiogenic isotope geochemistry and geochronology.

Module Content:

The module begins with an introduction to the principles of radioactive decay before describing several different radiogenic isotope systems (e.g. Sm-Nd, Rb-Sr, Lu-Hf, U-Th-Pb and Re-Os) and their applied uses in geology, earth and environmental sciences. Both conventional and novel uses of these isotopes are discussed. Laboratory classes primarily consist of gaining hands-on experience with processing, plotting and interpreting radiogenic isotope data. This will be achieved by working through case studies of published material. The module also gives an excellent grounding in mass spectrometry. The theory behind several different types of mass spectrometers is covered in lectures and reinforced with hands-on visits to various working laboratories using these instruments.

Learning Outcomes:

On successful completion of this module students should be able to:
• give a detailed account of the main types of mass spectrometers currently in use in geochemistry and geochronology laboratories worldwide
• describe in detail the theory and applications of the most widely used radiogenic isotopes in geology, earth and environmental sciences
• prepare samples for analysis and work with radiogenic isotope datasets
