Exploring deep Australia: 3-D imaging of the lithosphere beneath south-east Australia using multiple high density seismic arrays. The successful completion of this project will significantly improve our knowledge of the seismic structure of the Australian lithosphere, and hence improve our understanding of how the Australian continent came to be formed. In addition, the tomographic imaging methods that will be developed and applied to the individual and combined seismic arrays have a direct rele ....Exploring deep Australia: 3-D imaging of the lithosphere beneath south-east Australia using multiple high density seismic arrays. The successful completion of this project will significantly improve our knowledge of the seismic structure of the Australian lithosphere, and hence improve our understanding of how the Australian continent came to be formed. In addition, the tomographic imaging methods that will be developed and applied to the individual and combined seismic arrays have a direct relevance to the seismic imaging techniques used by the exploration industry. Finally, the creation of a combined dataset comprising records from ~300 stations will help keep Australia at the leading edge of observational seismology, as other countries (e.g. U.S.) begin to deploy very large seismic arrays.Read moreRead less
The Role of Hydrous Fluids in Fault Processes: An Experimental Study. The proposed project seeks to understand how hydrothermal reactions in fault zones affect various physical properties such as fault strength and permeability. The project will be conducted by performing high pressure experiments which simulate natural conditions. I will also develop new analytical techniques to characterize the microstructural evolution of faults, with a focus on understanding how any changes alter the hydrolo ....The Role of Hydrous Fluids in Fault Processes: An Experimental Study. The proposed project seeks to understand how hydrothermal reactions in fault zones affect various physical properties such as fault strength and permeability. The project will be conducted by performing high pressure experiments which simulate natural conditions. I will also develop new analytical techniques to characterize the microstructural evolution of faults, with a focus on understanding how any changes alter the hydrologic behaviour of the fault. This study will shed much needed information related to the mechanisms of earthquake nucleation, and to the formation mechanism of fault-hosted gold deposits.Read moreRead less
