Module GL3321: Geochemistry and analytical techniques

Contact hours & timing:

Module Learning Aims:

This module focuses on the theory and application of geochemistry, including major and trace elements as well as stable isotopes. The module covers both the acquisition of geochemical data as well as the principal numeric steps to test geological hypotheses with the data.

Module Content:

In terms of analysis, the module introduces many of the currently used methods for quantitative chemical analysis of minerals and rocks (X-ray fluorescence, inductively coupled plasma mass spectrometry and optical emission spectroscopy), for mineral determination (X-ray diffraction) and for imaging rocks and minerals (scanning electron microscopy, transmission electron microscopy, cathodoluminescence). Basic sample preparation techniques and site visits to various working laboratories are included. In terms of data familiarisation, the module covers a logical sequence of steps that guide users of geochemical data towards testing hypotheses.

Learning Outcomes:

On successful completion of this module students should be able to:

• describe the evaluate the use of major and trace elements as well as stable isotopes as tracers of geological processes
• describe sample preparation and analysis methods for geochemical studies and outline the types of scientific questions that can be addressed using geochemistry
• explain the principles of several current analytical techniques in geochemistry
• carry out calculations relating to processing analytical data
