My general research activities focus on understanding the physicochemical principles that determine mineral stability in the interior of the Earth. This goal is achieved through characterizing, by experimentation and the theory of mineral physics, equilibrium and the kinetics of mineral-melt-fluid systems in the Earth's crust. My research program is grounded in the use of diamond anvil cell assemblies, cold-seal and one-atmosphere furnaces to collect data relevant to pressing geologic questions. Subsequent thermodynamic models provide a means of applying experimental data to ancient and present geologic processes. The core of the research program is outlined below, but experimental studies are conducted in numerous other areas relating to Mineralogy, Petrology and Geochemistry.
Economic Geology Projects
I generally work on metal solubility and speciation in minerals, melts and magmatic volatile phases with applications to porphyry, epithermal, MVT and layered intrusion type depositions. Some of my current projects include:
- Cu, Au and Fe partitioning between a vapor, liquid and melt.
- Au association with and incorporation into various sulfide minerals (bornite, chalcopyrite, pyrite, pyrrhotite and arsenopyrite)
- The stability of select Cu-Fe, Fe-As and Fe- sulfide minerals as a function of temperature, pressure and sulfur activity/fugacity.
- Pt, Pd and Cu partitioning between a silicate and sulfide melt
- Fluorite solubility in a low salinity, high-F fluid.
Igneous and Metamorphic Petrology Projects
Experimental petrology has contributed significantly to our understanding of rock genesis. My research laboratories are well suited for a variety of experimental studies and are capable of producing the pressures and temperatures found deep within the Earth or other planetary bodies. I have diverse interests within these fields that include:
- Mineral-fluid alteration reactions (± bacteria assistance)
- Exchange of alkali elements between volatile phases, minerals and melts
- Serpentine dehydration kinetics in subduction zones
- Mantle wedge metasomatism
High Pressure Mineralogy and Petrology (with some Planetary Geology Applications)
My present research is centered on using diamond anvil assemblies to address problems in mineralogy, petrology and geochemistry. My research group uses the cell together with a synchrotron radiation source (APS, NSLS, CHESS, etc.) to explore the properties of minerals and fluids over a range of crustal conditions (300-3000 K and 0.001-200 GPa).
- High pressure studies of H2O-rich planetary bodies
- The incorporation of impurities into high-pressure phases
- The reactivity of CO2 in the deep mantle
- The kinetics of serpentine dehydration reactions
