The geochemistry of trace elements with variable oxidation states

Project: Research

Project Details

Description

The understanding of many earth processes is based upon an interpretation of differences in the relative abundance and/or distribution of elements which occur in more than one oxidation state. However, the redox states that control the geochemical behaviour of an element in a melt are not necessarily retained on cooling. This work aims to determine the oxidation states of geologically important elements, in situ under magmatic conditions, using XANES spectroscopy. The results will allow geological signatures to be correctly interpreted and allow models for topics ranging from ancient mantle temperatures to rates of melt migration to be better constrained.
