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.

Resolution of the Pb-diffusion in monazite paradox using a high-temperature contact aureole environment. This research will enhance our understanding of the thermal evolution of ancient mountain belts through time. Australian geoscientists are recognized internationally for their contributions to this field and the result from this study will further enhance our understanding of the evolution of Australia's crust. Because numerous ore deposits throughout Australia are hosted in ancient rocks, ....Resolution of the Pb-diffusion in monazite paradox using a high-temperature contact aureole environment. This research will enhance our understanding of the thermal evolution of ancient mountain belts through time. Australian geoscientists are recognized internationally for their contributions to this field and the result from this study will further enhance our understanding of the evolution of Australia's crust. Because numerous ore deposits throughout Australia are hosted in ancient rocks, documenting the timing of mineralization with respect to the thermal evolution of the host rocks may help to predict the location of mineral deposits in these settings; and each new mineral discovery contributes to the future prosperity of Australia and its communities.

Carbon and Hydrogen in Melts and Fluids in Planetary Interiors. The Australian community will benefit by the ownership of widely used high impact research in published earth science. This research defines the melting behaviour of silicate-rich materials (terrestrial planets, rocky-moons, meteorites) within the solar system. The research will be required for interpretation of Martian samples and will help to ensure that Australian laboratories participate in 21st Century investigations of the Sol ....Carbon and Hydrogen in Melts and Fluids in Planetary Interiors. The Australian community will benefit by the ownership of widely used high impact research in published earth science. This research defines the melting behaviour of silicate-rich materials (terrestrial planets, rocky-moons, meteorites) within the solar system. The research will be required for interpretation of Martian samples and will help to ensure that Australian laboratories participate in 21st Century investigations of the Solar System by virtue of their leading roles in understanding volcanism and melting behaviour at high pressures and under variable oxidation states. The research will address a national priority in sustainability of earth resources i.e. knowledge underpinning formation of Australian mineral resources.Read moreRead less
