In a nutshell….
Aqueous fluids play an important role
in magmatism, metamorphism, and the formation of ore deposits. My current
research examines how hydrous silicate melts and hydrothermal fluids transport
and deposit metals. The work
involves field and geochemical studies as well as in situ
spectroscopic experiments on relevant systems at elevated pressures and
temperatures in specially designed hydrothermal diamond anvil cells. The
results obtained are used to enhance models of ore formation and mass
transfer in the crust of the Earth.
Current
research topics include:
- Geochemical and fluid
inclusion studies of granite-related ore forming systems.
- X-ray absorption
spectroscopic (XAS) investigations of the structure and stability of
ore metal complexes in solvothermal fluids.
- In situ spectroscopic analysis
of hydrous granitic melts and aqueous fluids using the hydrothermal
diamond anvil cell.
- The solubility of
transition metal oxides in supercritical water.
- Studies of corrosion and
corrosion product transport in supercritical water reactors.
Students interested
in: (1) ore deposits, granites and granitic pegmatites, and/or (2) the geochemistry
of fluids in the Earth’s crust 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 natural fluid inclusions and on experimental solutions in
hydrothermal diamond anvil cells are undertaken at various synchrotron
light sources. I am currently using different x-ray microprobes at the Advanced Photon Source, Argonne
National Laboratory, and the European
Synchrotron Radiation Facility, Grenoble,
France.
Future studies will also be carried out at the Canadian Light Source (CLS) in Saskatoon.
