My work covers four main areas of mineralogy: crystal chemistry and mineral physics, granitic pegmatites, environmental mineralogy, and the mineralogy of gemstones.
Crystal Chemistry and Mineral Physics:
The Little Nahanni Pegmatite Group: Arguably world's best example of the albite-spodumene class of granitic pegmatites. Our work has shown that the Group is an important potential future source of rare elements such as Li, Nb and Ta. Recently I began research on granitic pegmatites in southeastern British Columbia.
The mineralogy, geology and origin of Canada's first significant emerald deposit, the Crown showing in southeastern Yukon.
Recently I have begun a new project on metamorphic gem minerals of the Slocan Valley.
Environmental Mineralogy: Mineralogy of base metal tailings with a variety of sulfide contents. My objectives are to determine rates of oxidation, to evaluate the validity of laboratory experiments used for the prediction of acid mine drainage potential, and to develop better predictive models. I am also involved in studies of natural acid rock drainage at Limonite Creek in northwestern British Columbia and of mine wastes and neutralization potential.
Geomicrobiology is an important new area of research. In the early `90s I was involved in several bioleaching projects. In order to learn more about the field of geomicrobiology, I organized a short course on biological/mineralogical interactions. I continue to do some research in bioleaching today.
The majority of my research is done in collaboration with others at UBC and at the California Institute of Technology, Oak Ridge National Laboratory, Cambridge University, and the Universities of Hamburg and Manitoba.
