Key Research

• Nickel mineral system analysis
• Research and development of PGE-based exploration tools towards Ni-Cu-PGE mineralisation associated with mafic and ultramafic systems,
• The Early Earth
• Geochemistry of PGEs
• Role of volatiles in the petrogenesis of Precambrian mafic and ultramafic systems
• Role of chromite in the fractionation and concentration of the PGEs
• The use of in-situ stable isotope determination as a tracer of mantle metasomatic processes
