Summary

Research Interests

My research focuses on understanding the geochemistry of hydrothermal systems, in particular how metals are transported and deposited to form ore deposits. Current research areas include:

  • Metal transport and controls of fertility in porphyry ore deposits
  • Mineral chemistry of hydrothermal alteration and exploration applications
  • Use of transition metal isotopes (Zn Cu, Fe) for tracing metal sources, flow pathways and depositional mechanisms
  • Development of laser ablation ICPMS for the determination of metals in fluid inclusions
  • Geochemistry of sediment-hosted ore systems
  • Geochemistry of epithermal ore fluids
  • Genesis of high grade iron ore deposits

Plenary Lectures

Plenary Speaker: 10th Biennial SGA Meeting, Townsville, Australia, August 2009

"Making metal super-charged ore fluids: The key to hydrothermal base-metal ore formation?"

Co-authors: David R. Cooke (CODES, ARC Centre of Excellence in Ore Deposits, University of Tasmania), Dominik J. Weiss, Helen L. Crowther, Barry J. Coles (Department of Earth Science and Engineering, Imperial College London), Teresa E. Jeffries (Department of Mineralogy, Natural History Museum), Chris G. Ryan, Jamie Laird (CSIRO Exploration and Mining, School of Physics, University of Melbourne)

Abstract. The formation of large hydrothermal ore deposits is optimized by several factors: efficient extraction of metals from the source region, elevated metal concentrations in hydrothermal fluids, high fluid flux, effective focusing of fluids into a limited rock volume and efficient precipitation. Of these parameters, metal solubility displays the widest variability (up to 4 orders of magnitude) and is potentially the most important. A case study tracing metal transport in the Irish orefield suggests that efficient extraction from the source rocks is critical for the formation of economic deposits. The observation that ore fluids trapped in sphalerite contain orders of magnitude more metal than those in quartz implies that ore deposition is related to the influx of metal super-charged brines produced by this efficient leaching process. Large parts of the hydrothermal system in space and time may be barren due to a failure to attain efficient extraction and transport conditions.
