Current research:

Currently, I have a group of 7 M.Sc. students and 2 B.Sc. students working on fluid and melt inclusion studies in hydrothermal-magmatic ore-forming systems, with a focus on:

(i) platinum-group element deposits in unconventional (porphyry) and conventional (mafic-ultramafic) settings, intrusion-related Au-W-Mo deposits, and some sediment-hosted base metal systems

(ii) fluid inclusion stable isotope and noble gas isotope systematics in ore-forming system Sr, Pb, He, Xe, Ar, Kr, Ne),

(iii) the application of synthetic fluid inclusions and novel hydrothermal experimental techniques in quantifying platinum-group element and base metal solubility in aqueous and non-aqueous fluid.

Studies are in progress at the Bushveld Complex (South Africa), Greendale Complex (Nova Scotia), 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 Craig Hart (University of British Columbia), Roberto Moretti (University of Naples II), Ilya Veksler (GFZ Potsdam), E.T.C. Spooner/Colin Bray/J. Mungall (University of Toronto), Dan Kontak/Joe Petrus/Harold Gibson (Laurentian University), T. Pettke (University of Bern) and C.Heinrich/M. Guillong/Z.Zajacz (ETH Zürich), J. Potter and F. Longstaff (University of Western Ontario), and Alex Hofstra and Andrew Hunt (USGS). A major goal of these studies is to develop cost-effective geochemical exploration criteria that may be used to identify mineralized intrusions.Close collaborations with ETH Zurich and Laurentian University 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.

Additionally, I am collaborating with Dr. Katie Cottreau-Robins at the Nova Scotia Museum of Natural History on a project involving the use of LA-ICPMS to determine provenance of copper artifacts from pre-contact native archeological sites in the Maritimes. Our research is funded by NSERC, CFI, NSRIT, Yukon Geoscience, Geoscience NWT, the Government of Canada, KGHM International, and Vale Canada.
