Field-based research projects are currently examining interactions between crustal deformation, fluid transport and ore deposition in mesothermal, fault and shear zone hosted gold vein systems in the Kalgoorlie-Norseman area of Western Australia. We have also been investigating faulting processes and deformational controls on the dynamics of fluid flow in spectacular intrusive-related and fault-hosted gold deposits at Porgera in the western highlands of Papua New Guinea. A new program is examining the role of deformation processes in modifying the geometry, internal structures and ore grades in Archaean nickel sulphide ore deposits in the Kambalda region, Western Australia.

focus on the influence of reactive pore fluids on the mechanical behaviour of faults, particularly effects of dissolution-precipitation prosesses on the development of fault rocks. In the Geology Department, this work is being conducted using in situ deformation stages which allow microstructural development to be observed during deformation of analogue materials on a microscope stage. At RSES, we are using high pressure, high temperature rock deformation facilities to examine the mechanical behaviour of simulated faults in the presence of reactive pore fluids.

Numerical modelling studies are being conducted in collaboration with Dr Mark Knackstedt (Research School of Physical Sciences and Engineering, ANU) to apply percolation theory to examine growth of fault networks and evolution of the architecture of fluid migration in fault/shear networks during progressive crustal deformation. This work is being applied to understanding localisation of ore systems. Further research in collaboration with Dr Jean Braun (RSES, ANU) is using finite element modelling strategies to investigate fluid flow in networks of faults and shear zones associated with the genesis of mesothermal gold systems...
