Current Research Projects

  • The origin and exploration significance of zinc- (gahnite, staurolite, ilmenite, biotite) and manganese-bearing minerals (garnet, pyrophanite) with Broken Hill-type Pb-Zn-Ag mineralization in the Olary Domain of South Australia (with current Ph.D. student, Adriana Heimann) and the Broken Hill Domain in New South Wales, Australia (with Graham Teale, Teale and Associates; Ian Plimer, University of Melbourne; and Mark Fanning, Australian National University) see abstract, see fig. 1 & fig. 2
  • Fluid inclusion and sulfur isotope systematics of epithermal gold deposits (Efemcukuru, Kisladag, and Mayislar), Turkey (with Zeki Billor, Auburn University; Selahattin Yildrim, Mineral, Research and Exploration (MTA), Turkey see abstract, see fig. 3
  • The mineralogy and geochemistry (fluid inclusions and stable isotopes) of epithermal gold deposits in the Greek Islands of the Aegean Sea (with Stellios Tombros and Karen St. Seymour; University of Patras). see abstract, see fig.4
  • The effects of phosphonate inhibitors on ettringite in highways (with current M.S. student, Patrick Hook; Bob Cody, Iowa State University) see fig 5
  • The vanadium-tellurium-gold association at the epithermal Tuvatu gold deposit, Fiji (with Nancy Scherbarth, Tectonic Resources, Australia). see abstract, see fig. 6
  • The genetic relationship of alkaline magmatism to the formation of gold telluride mineralization in the central Montana alkalic belt
  • The effects of metamorphism on the metamorphosed Angas Pb-Zn-Ag deposit, South Australia (with Ross Both, University of Adelaide)

Recently Completed Projects

  • Mineralogy and stable isotope geochemistry of gold-silver telluride mineralization in the Berners Bay district, Alaska (with former MS student, Sally Casey)
  • Zinc-rich spinels associated with Proterozoic base metal sulfide occurrences, Colorado, and their use as guides to metamorphosed sulfide deposits (with former MS student Adriana Heimann) see fig. 7
  • The distribution of gold and tellurides in Emperor gold-silver telluride deposit, Fiji (with former MS student, David Pals)
  • Petrological, mineralogical, fluid inclusion and stable isotope characteristics of the Tuvatu gold-silver telluride deposit, Fiji (with former MS student, Nancy Scherbarth) see fig. 8
  • Telluride mineralogy of the Golden Mile, Kalgoorlie, Western Australia (with former MS student, Jill Shackleton)
