Research Interests
Dr. Spry's research interests are in economic geology, mineralogy and petrology and include the geochemistry of metallic and non-metallic deposits. He is particularly interested in the petrological, mineralogical, structural, geochronological, stable isotope and fluid inclusion characteristics of epithermal and mesothermal gold deposits, as well as the effects of metamorphism on massive sulfide deposits. Current research projects include: the origin of gold telluride deposits in Greece, Fiji, Montana, and Papua New Guinea; sulfidation-oxidation relations associated with metamorphosed ores at the Angas Pb-Zn-Ag deposit, South Australia; the origin of meta-exhalites associated with metamorphosed massive sulfides in the southern Curnamona Province, Australia (including the Broken Hill Pb-Zn-Ag deposit); the origin of epithermal and mesothermal gold deposits in Turkey; the crystallographic characterization of precious metal sulfides and sulfosalts.
