This linkage was established to bring expertise in isotope geochemistry into CODES for application to a range of ore deposit problems in the Location, Formation and Discovery programs. The collaboration involves CI’s Janet Hergt, Jon Woodhead, Roland Mass; CODES postdoc. Chad Paton at the University of Melbourne node; and Leonid Danyushevsky, Sebastian Meffre, Tony Crawford, Ross Large, Trevor Falloon, Zaoshan Chang and CODES postdoc Helen Thomas at the CODES hub at UTAS.

This collaborative research is focussed on developing new techniques for measuring lead and copper isotopes in minerals and applying these isotopes to improve understanding of the source and timing of metals in ore deposits. A significant outcome to date has been the development of an innovative new LA-ICPMS technique for measuring Pb isotopes in pyrite, which has been applied to produce a new genetic model for the giant Sukhoi Log gold deposit in Russia and published in Geochemica.
