Crustal Growth in the Northern Tasmanides. The Australian and Queensland governments have invested over $3 million to undertake deep crustal seismic imaging in northern Queensland, providing an extensive new geophysical dataset capable of modelling crustal architecture and geological evolution to unprecedented levels. However, such models will remain untested unless the data is groundtruthed by analysis of rocks at the surface, providing a geological framework for extrapolation into the deep Ea ....Crustal Growth in the Northern Tasmanides. The Australian and Queensland governments have invested over $3 million to undertake deep crustal seismic imaging in northern Queensland, providing an extensive new geophysical dataset capable of modelling crustal architecture and geological evolution to unprecedented levels. However, such models will remain untested unless the data is groundtruthed by analysis of rocks at the surface, providing a geological framework for extrapolation into the deep Earth. The framework critically describes when and how crustal blocks were assembled, and the integrated information will generate evolutionary 3D models that will substantially improve mineral exploration targeting in the region.Read moreRead less
An integrated approach to modelling granular materials in a pavement system. The Australian transportation system consists of some 900,000 km of paved roads valued in excess of 300 billion dollars. Hundreds of millions of dollars are spent each year on maintenance. About 90% of these paved roads are constructed with granular base and sub-base materials. This project will develop an accurate constitutive model for granular materials and a numerical method that are essential in predicting the life ....An integrated approach to modelling granular materials in a pavement system. The Australian transportation system consists of some 900,000 km of paved roads valued in excess of 300 billion dollars. Hundreds of millions of dollars are spent each year on maintenance. About 90% of these paved roads are constructed with granular base and sub-base materials. This project will develop an accurate constitutive model for granular materials and a numerical method that are essential in predicting the life-long performance of pavements. The project will lead to improved pavement design procedures, which, together with the research training offered through the conduct of the work, will result in cost-effective and highly reliable pavement designs.Read moreRead less
Trace element analysis of diamond: new applications to diamond fingerprinting and genesis. The project will provide new insights into the processes by which diamond crystallises in the Earth's mantle. A better understanding of these processes can lead to improved models and techniques for diamond exploration, enhancing the prospect of finding new deposits in Australia and abroad.

The project will provide new insights into the processes by which diamond crystallises in the Earth's mantle. A better understanding of these processes can lead to improved models and techniques for diamond exploration, enhancing the prospect of finding new deposits in Australia and abroad. The project will test the potential of trace-element microanalysis to fingerprint diamonds by source. If successful, this technology will provide economic benefits by reducing theft and illegal mining, which represent significant losses to legitimate companies. Application of this Australian development could reduce the circulation of "conflict diamonds", which would have real social benefits worldwide, especially in some developing countries.Read moreRead less
Composition, structure and evolution of the lithospheric mantle beneath southern Africa: improving area selection criteria for diamond exploration. The project will provide new insights into the detailed structure of the deep Earth (to about 250 km) and identify and predict zones of weakness that could focus kimberlite magmas that carry diamonds to the surface. A better understanding of the nature and location of these structures will lead to improved models for diamond exploration, enhancing th ....Composition, structure and evolution of the lithospheric mantle beneath southern Africa: improving area selection criteria for diamond exploration. The project will provide new insights into the detailed structure of the deep Earth (to about 250 km) and identify and predict zones of weakness that could focus kimberlite magmas that carry diamonds to the surface. A better understanding of the nature and location of these structures will lead to improved models for diamond exploration, enhancing the prospect of finding new deposits in Australia and abroad. Innovations in integrating information from geochemistry and geophysics, development of 3D imaging techniques, and extrapolation to past geological scenarios will provide new exploration tools, and also maintain our high international profile in research relevant to the National Priority on Developing Deep Earth Resources.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

This project will apply 3D X-ray micro-tomography and model-based computational analysis to develop innovative approaches to the micro-structural characterisation of metallurgical coke. This has significant ramifications for the iron industry since coke characterisation is of primary importance to improved blast furnace productivity. The project will deliver new quantitative indices of coke microstructure, develop models for simulation of micro-structural properties and coke transport properties, and examine coke reactivity in 3D contexts. This project will also be the first study to use multi-scale 3D X-ray tomographic analysis to examine the structural dynamics of coke during both its production and its use in the blast furnace.Read moreRead less

WA suffers unusually high exposure to severe tropical and extra-tropical weather, from its size and geographical location. This project will develop enhanced data assimilation and modelling techniques, using emerging high-resolution satellite and other data to improve the timeliness, accuracy and reliability of weather forecasts for WA. Outcomes include: improved forecast systems for predicting severe weather affecting WA (and consequently Australia), and ensemble forecast systems that provide valuable probabilistic information, such as confidence limits in the forecasts. Better forecasts issued earlier for severe weather events will allow appropriate planning and management measures, thereby reducing their present high social and economic cost.Read moreRead less

The project will construct a clear picture of faunal change during the Late Pleistocene, a period of well documented extinctions of giant animals (megafauna). Archaeological excavation at Riversleigh, in north-west Queensland and palaeontological excavation at Cuddie Springs, in northern N.S.W. will complete a picture of the animals, people and environment of the prehistoric period at each site. With this information, the roles of climate and people in the extinction process can be assessed.

There is a need to predict landscape processes into the future using simulation models. The limited availability of appropriate information on the soil is a fundamental barrier to this crucial modelling. This project will develop an inference system to predict soil properties from the very limited information. The results will be used to describe soil quality, to monitor the effects of agricultural management, and principally to provide information needed by policy makers concerned with sustainable land use.Read moreRead less
