In order to progress in our understanding of processes occurring in igneous systems on Earth and other terrestrial planets, it is important that we have the capability of simulating experimentally the conditions of formation for these rocks. Such experimental simulation presents a particular challenge, as it involves the simultaneous application of pressure and temperature in chemically complex and highly reactive systems. In our laboratories we focus on investigations of the Earth's interior - we mainly work on processes in the Earth's upper part of mantle and crust.
Experimental facilities located in our laboratory include apparatus designed to take natural and synthetic compositions to pressures and temperatures that are found in the Earth's crust and upper mantle. These facilities include end-loaded piston-cylinder apparatus (up to 3.5 GPa, 1600°C), multi-anvil apparatus (up to 15 GPa, 2000°C), large volume box furnaces, and two vertical one atmosphere furnaces (1600°C). Associated auxiliary equipment includes welding apparatus, balances, polishing and cutting facilities, and several drying furnaces.
Phase relations in the Earth's upper mantle
- High-pressure high-temperature experiments to investigate the transition from garnet lherzolite to spinel lherzolite in refractory compositions
- Thermodynamic modeling in realistic mantle compositions using free energy minimization techniques
Physics and Chemistry of Minerals
- Thermodynamics of transition metal bearing oxides and silicates with applications to processes in the Earth's upper mantle
- Phase transitions at low temperatures, magnetic ordering, thermodynamics
The partitioning of trace elements between minerals and melts
- Trace element partitioning between accessory phases and different melts (carbonatite, basalts etc.)
- Trace element partitioning between Ti-bearing minerals and melts: High-pressure high-temperature experiments with applications to subduction zone processes
- Experimental simulation of carbonatite metasomatism: Trace element partitioning between mantle minerals and carbonatite melts
Subduction zone processes
- Trace element transfer during melting of subducted oceanic crust
- Mobility of refractory elements in melts and fluids (e.g. Ti, Zr, Hf)
Experimental Studies relevant to ore genesis
- Experimental studies on immiscible liquids in Fe and P-bearing systems with applications to the genesis of nelsonites and phoscorites
- Trace element partitioning between ilmenite and melts with implications for the origin of large ilmenite deposits
Experimental Planetary Science
- Trace element fractionation by iron-titanium oxides with implications for the evolution of a lunar magma ocean
