Current research:
1. Quantitative fluid and melt inclusion studies in magmatic ore-forming systems , with current focus on: (i) platinum-group element deposits in unconventional (porphyry) and conventional (mafic-ultramafic) settings, and (ii) intrusion-related Au-W-Mo deposits. Studies in progress at the Bushveld Complex (South Africa), Sudbury Igneous Complex (Canada), Skaergaard Complex (Greenland), Tintina Gold Belt (Yukon and Alaska), and a variety of alkalic Cu-Au porphyry systems in southern and central British Columbia (Afton, Mt. Milligan). Collaborations with A. McBirney (University of Oregon), E.T.C. Spooner and J. Mungall (University of Toronto), T. Pettke (University of Bern) and C. Heinrich/M. Guillong (ETH Zürich). A major goal of these studies is to develop cost-effective geochemical exploration criteria that may be used to identify mineralized intrusions. A close collaboration with ETH
Zurich involves the routine application of laser ablation ICP-MS in analyzing single fluid and melt inclusions for a variety of trace elements including ore metals
2. Hydrothermal experimental studies , with current focus on: (i) the application of synthetic fluid inclusions in understanding stable isotope systematics in ore-forming systems (Sr, Pb), and (ii) the application of synthetic fluid inclusions and novel hydrothermal experimental techniques in quantifying platinum-group element solubility in aqueous and non-aqueous fluids. Studies in progress include: (i) the determination of Sr and Pb isotope systematics in hypersaline ore fluids in the footwall of the Sudbury Igneous Complex by multi-collector ICP-MS (collaboration with T. Pettke, University of Bern and F. Oberli, ETH Zürich), and (ii) solubility measurements of native platinum and platinum-bearing minerals in salt melt phases (collaboration with C. Heinrich and M. Aerts, ETH Zürich).
3. Trace element analysis of slags and metallic artifacts , with current focus on delineating metal sources and smeltering techniques for Bactrian and Judean bronzes (collaboration with J. Greenough, University of British Columbia).
