A multidisciplinary study of the Karoo Basin: chronology of a mass extinction, configuration of a supercontinent. Development plans for Australia's North-West (NW) shelf will expand the existing supply of natural gas and help manage greenhouse gas emissions through an innovative carbon sequestration project. A better understanding of well-exposed geology of the Karoo Basin will help evaluate the submarine deposits of Australia's NW shelf, essential for both improving yield from the new Gorgon ga ....A multidisciplinary study of the Karoo Basin: chronology of a mass extinction, configuration of a supercontinent. Development plans for Australia's North-West (NW) shelf will expand the existing supply of natural gas and help manage greenhouse gas emissions through an innovative carbon sequestration project. A better understanding of well-exposed geology of the Karoo Basin will help evaluate the submarine deposits of Australia's NW shelf, essential for both improving yield from the new Gorgon gas fields and understanding subterranean reservoir capabilities for carbon dioxide injection This study will also improve our scientific understanding of the timing and mechanisms of the end-Paleozoic mass extinction, the most significant event in the history of life on Earth.Read moreRead less
Assessment of the Seismic Hazard in South-East Queensland utilizing earthquake simulations. Assessment of seismic hazard in Australia is hampered by relatively few instrumental records of past earthquakes. Supercomputer simulations of long-term earthquake activity and strong ground motion, provide an alternative method for estimating the risk posed by earthquakes. The aim of this project is to construct a physical model for South-East Queensland incorporating the major faults and rock units of ....Assessment of the Seismic Hazard in South-East Queensland utilizing earthquake simulations. Assessment of seismic hazard in Australia is hampered by relatively few instrumental records of past earthquakes. Supercomputer simulations of long-term earthquake activity and strong ground motion, provide an alternative method for estimating the risk posed by earthquakes. The aim of this project is to construct a physical model for South-East Queensland incorporating the major faults and rock units of the region. In conjunction with earthquake simulation software of the Australian Computational Earth Systems Simulator, this model will be employed to analyse the spatial and temporal variability of earthquake activity and the ground motion resulting from these earthquakes.Read moreRead less
New developments in 3D electrical resistivity imaging of the shallow subsurface. This project is concerned with developing improved procedures for electrical imaging of hidden geological features in the subsurface. These techniques are required to solve urgent problems associated with important issues, such as natural hazards, disposal of dangerous waste, groundwater and construction of major buildings and tunnels. The project will develop new hardware, software and interpretation aids, as well ....New developments in 3D electrical resistivity imaging of the shallow subsurface.

Chronostratigraphic Framework for the Devonian Canning Basin - A Multidisciplinary Record of Environmental Change. Our detailed chronostratigraphic framework for Canning Basin and the biomarker data on source rock history provides an increased understanding of the resource potential of the basin and similar settings worldwide. Furthermore this high-fidelity data will be used by companies to develop the 'next' generation of hydrocarbon industry modelling workflows. Our research program also has i ....Chronostratigraphic Framework for the Devonian Canning Basin - A Multidisciplinary Record of Environmental Change. Our detailed chronostratigraphic framework for Canning Basin and the biomarker data on source rock history provides an increased understanding of the resource potential of the basin and similar settings worldwide. Furthermore this high-fidelity data will be used by companies to develop the 'next' generation of hydrocarbon industry modelling workflows. Our research program also has important environmental implications; providing insight into drivers for Devonian mass extinctions and as periods of past biotic crises become increasingly understood they can provide critical insights into determining the thresholds of environmental change, which may potentially serve as analogues for present-day global climate change scenarios.Read moreRead less
3D seismic velocity structure for geothermal exploration: a novel approach combining ambient and passive seismic methods. Australia hosts many geological locations that have the potential for geothermal energy production. This is a sustainable power resource and employs diverse technological approaches depending on local conditions.

Australia hosts many geological locations that have the potential for geothermal energy production. This is a sustainable power resource and employs diverse technological approaches depending on local conditions. We aim to pilot a new seismic imaging method, which could become a standard in geothermal exploration around the world, to investigate natural heat sources buried in the crust. Tasmania is an ideal pilot location with active geothermal exploration tenements held by a locally-based company.Read moreRead less
Three-dimensional magnetotelluric imaging of lithospheric-scale mineral systems from source to deposit. Geochemical studies indicate that world-class mineral deposits are partly sourced from fluids emerging from Earth's mantle and lower crust. Finding major mineral deposits in the future will therefore require knowledge of which parts of the crust and mantle yield the most prospective locations. However, there are few methods that can image deep Earth resources, and these can be very expensive ....Three-dimensional magnetotelluric imaging of lithospheric-scale mineral systems from source to deposit. Geochemical studies indicate that world-class mineral deposits are partly sourced from fluids emerging from Earth's mantle and lower crust. Finding major mineral deposits in the future will therefore require knowledge of which parts of the crust and mantle yield the most prospective locations. However, there are few methods that can image deep Earth resources, and these can be very expensive. We propose to develop the magnetotelluric method as a low-cost and rapid approach for delineating 3D information on deep mineral systems beneath existing major deposits, and adapting this to explore in greenfield locations.Read moreRead less
Optimisation of Signal-to-Noise Ratio in Electrical and Electromagnetic Investigations. Electrical and electromagnetic geophysical methods have been used extensively for mineral exploration, and are developing a role in salinity mapping and contaminant identification. To enhance the utility of such methods for very shallow targets (in the case of salinity) and deep targets (minerals beneath regolith)improved signal processing methods are required. The project involves the development of time-ser ....Optimisation of Signal-to-Noise Ratio in Electrical and Electromagnetic Investigations. Electrical and electromagnetic geophysical methods have been used extensively for mineral exploration, and are developing a role in salinity mapping and contaminant identification. To enhance the utility of such methods for very shallow targets (in the case of salinity) and deep targets (minerals beneath regolith)improved signal processing methods are required. The project involves the development of time-series processing techniques using robust-statistical methods and remote-referencing to improve signal-to-noise data quality. Instrumentation hardware and software developments are required for in-field data acquisition and interpretation, applied to direct current (DC) resistivity, induced polarisation (IP) and time-domain EM (TEM).Read moreRead less
