Transition metal isotope variations in iron oxide-copper-gold (IOCG) ore deposits as a potential
mineral exploration tool
Since the discovery of the giant Olympic Dam deposit in South Australia, iron oxide-copper-gold
(IOCG) ore deposits have increasingly been recognised as a distinct and important ore deposit type.
This project will investigate transition metal (Fe-Zn) isotope variations in selected IOCG ore deposits
and their extensive metasomatic haloes, with the possibility of working on deposits either within
Brazil, e.g. Cristalino, Sossego, or elsewhere. The main objectives are to relate Fe-Zn isotopic variations
to mineral paragenesis and other geological and geochemical variations, and to determine the
potential mineral exploration value of these isotopic techniques.
The research will be mainly lab-based, involving MC-ICP-MS isotopic analysis of Fe and Zn and trace
element analysis at the National Centre for Isotope Geochemistry in UCD, electron microprobe analysis
and conventional stable isotope analysis (S, O, H), the last in collaboration with Dr Adrian Boyce
(Scottish Universities’ Environmental Research Centre, East Kilbride, UK).
We are seeking applicants with a good honours BSc or MSc degree in Geology or Geochemistry.
Research experience in hydrothermal geochemistry, or in any of the above analytical techniques,
would be a distinct advantage but is not essential. If you are interested in this project, please email Dr
Julian Menuge ([email protected]) for more information. In order to apply, you will need to supply
your CV, the names and email addresses of three referees and a transcript showing the grades or
marks obtained in your university courses.
