My research interests focus on hydrothermal fluids throughout the crust and the ore deposits that form from, or are modified by, these fluids. Current interests include high-grade iron ores in Brazil, Australia and the Lake Superior region; both Carlin-type and low-sulfidation gold deposits in Nevada; PGE ores in the Duluth Complex and South Africa; and massive sulfide deposits in the U.S. and Canada. Fluid inclusions can provide direct samples of the causative fluids in all of these ore deposit types and continue to be an emphasis in many of my student’s studies. In addition laboratory work includes electron microprobe and SEM analyses, stable isotope analyses, and recently the magnetic properties of mafic igneous rocks.
