Research interests
My research is in geochemistry and focusses on cation behaviour in sphalerite (ZnS) to aid critical metals exploration and extraction. This includes:
- The localisation and abundance of critical metals such as indium, gallium, germanium, arsenic, antimony and manganese;
- Investigating oxidation states and lattice constraints on elements recovered from sphalerite;
- Distinguishing ore deposits types with cation concentrations in economically important minerals and different redox environments.
Secondary research includes:
- Lattice constructs and bonding arrangements of elements in sulfides.
- The analysis and synthesis of sulfide calibration standards for laser ablation mass spectrometry (eg: LA-ICP-MS);
- Experimental synthesis of sphalerite with metallic solid solutions.
Successful X-ray Absorption Near Edge Spectroscopy (XANES) experiments:
- Project lead: "Speciation of Arsenic and Thallium in Sphalerite (ZnS)";
- Project lead: "Iron oxidation states in sphalerite: a redox study on different ore deposit types";
- Assisted: "Characterisation of garnet related to critical metal-enriched U-REE-Cu-Au mineralisation in Queensland, Australia".
