Precise location of earthquakes: combining arrival times with Coda Wave Interferometry. The location of earthquakes is important for improving our knowledge
of the contemporary plate tectonic regime, mapping of active crustal faults and quantifying risk posed to population centres and infrastructure. Precise relative location of micro-earthquakes also has important industrial applications, including mapping the extent of underground geothermal reservoirs, and in exploration for ore producing ....Precise location of earthquakes: combining arrival times with Coda Wave Interferometry. The location of earthquakes is important for improving our knowledge
of the contemporary plate tectonic regime, mapping of active crustal faults and quantifying risk posed to population centres and infrastructure. Precise relative location of micro-earthquakes also has important industrial applications, including mapping the extent of underground geothermal reservoirs, and in exploration for ore producing hydrothermal systems. This project will advance the field of earthquake location by introducing new techniques that will increase the amount of seismic information that can be used for both research and national monitoring purposes.

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
Global Lithosphere Architecture Mapping. Compositional domains in the subcontinental lithospheric mantle reflect the processes of continental assembly and breakup through Earth's history. Their boundaries may focus the fluid movements that produce giant ore deposits. Mapping these boundaries will provide fundamental insights into Earth processes and a basis for the targeting of mineral exploration. We will integrate mantle petrology, tectonic synthesis and geophysical analysis to produce the f ....Global Lithosphere Architecture Mapping. Compositional domains in the subcontinental lithospheric mantle reflect the processes of continental assembly and breakup through Earth's history. Their boundaries may focus the fluid movements that produce giant ore deposits. Mapping these boundaries will provide fundamental insights into Earth processes and a basis for the targeting of mineral exploration. We will integrate mantle petrology, tectonic synthesis and geophysical analysis to produce the first maps of the architecture of the continental lithosphere, to depths of ca 250 km. These maps will provide a unique perspective on global dynamics and continental evolution, and on the relationships between lithosphere domains and large-scale mineralisation.Read moreRead less
