Research

†† Aqueous fluids play an important role in magmatism, metamorphism and the formation of ore deposits.My research aims to understand the evolution and physicochemical properties of ore-forming hydrous silicate melts and associated hydrothermal fluids.To this end, my group is engaged in field and geochemical studies of major mineral deposits as well as experimental x-ray scattering and spectroscopic investigations of metal-bearing silicate melts and aqueous solutions over a range of geologically relevant pressures and temperatures.The data are used to model metal transport and deposition in magmatic and hydrothermal systems.

Projects

  • Geochemical and fluid inclusion studies of granitic pegmatites and granite-related ore deposits.
  • The development and application of new high temperature-pressure cells.
  • X-ray absorption spectroscopic (XAS) investigations of ore metal complexes in solvothermal fluids.
  • Chemical controls on solubility of metal oxides in supercritical water.
  • Studies of corrosion and corrosion product transport in supercritical water-cooled reactors.

Students interested in graduate research on granitic pegmatites, ore deposits and/or hydrothermal geochemistry are invited to contact me. aanderso at stfx.ca

Patents

ELASTIC-PART IMMERSION CELL - Patent number 5,422,718. Issued in the United States June 6, 1995.

Synchrotron Radiation Sources

X-ray spectroscopic studies on experimental samples in hydrothermal diamond anvil cells are undertaken at different synchrotron light sources. I am currently using x-ray micro-beam facilities at the Advanced Photon Source (APS), Argonne National Laboratory, Chicago, the European Synchrotron Radiation Facility (ESRF), Grenoble, France, and the Canadian Light Source (CLS), Saskatoon, Saskatchewan.
