Thermal structure and evolution of the Australian continent. Australia contains 40% of the world's known uranium resources. Uranium, with thorium and potassium, are heat-producing elements which affect the way temperature varies within the Earth. Outcomes from this project will lead to a better understanding of the potential for geothermal energy in Australia and provide a framework for assessing Australia's uranium resource. Understanding the crustal thermal regime is also fundamental to our kn ....Thermal structure and evolution of the Australian continent. Australia contains 40% of the world's known uranium resources. Uranium, with thorium and potassium, are heat-producing elements which affect the way temperature varies within the Earth. Outcomes from this project will lead to a better understanding of the potential for geothermal energy in Australia and provide a framework for assessing Australia's uranium resource. Understanding the crustal thermal regime is also fundamental to our knowledge of many earth processes. The project will enhance Australia's international research standing, provide training for an early career researcher and contribute to the development of an environmentally sustainable Australia, a National research priority.Read moreRead less
CRATON EDGES AND SUTURES IN THE AUSTRALIAN MANTLE. A major seismic experiment using recording of distant earthquakes will be used to provide images of 3-D structure in the Earth's crust and mantle along the length of the edge of the Precambrian Australian Shield and across the suture between the South and North Australian cratons within the Shield. Seismic structures derived from different classes of geodynamic models will be compared with seismic results derived from a variety of styles of dat ....CRATON EDGES AND SUTURES IN THE AUSTRALIAN MANTLE. A major seismic experiment using recording of distant earthquakes will be used to provide images of 3-D structure in the Earth's crust and mantle along the length of the edge of the Precambrian Australian Shield and across the suture between the South and North Australian cratons within the Shield. Seismic structures derived from different classes of geodynamic models will be compared with seismic results derived from a variety of styles of data interpretation, including seismic tomography. The experiment will improve understanding of the range of physical processes associated with rifting and building of continents.Read moreRead less
Seismic constraints on the assembly of cratons. Improved definition of the 3-D seismological structure and nature of the major lithospheric blocks in Australia and their assembly to form the present-day continent will be sought from seismological data. The inclusion of information on the depth extent and character of the lithosphere will improve geological understanding of the evolution of the continent, with relevance to the interaction of the crust and mantle and the placement of mineral res ....Seismic constraints on the assembly of cratons.
