This project aims to develop and test models to evaluate past tectonic processes and configurations in South-east Australia, using both new and existing geological, geophysical and isotopic data. Over the past 550 million years, plate tectonic processes have formed metal-rich mineral deposits in South-east Australia. The project will identify areas of high potential for economically valuable ore deposits, enabling more efficient prioritisation of mineral exploration efforts. This is expected to increase the probability of significant ore deposit discoveries leading to national economic benefit.Read moreRead less
Experimental constraints on the genesis of gold-rich ore deposits. The project will provide a new set of tools to explore for gold-rich ore deposits in Australia and globally. By integrating geochemical studies with cutting-edge experiments carried out at three Australian universities in strategic partnership with industry, the outcomes of this project will provide much needed knowledge to predict the locations of large gold-rich deposits that are concealed beneath vast expanses of the Australia ....Experimental constraints on the genesis of gold-rich ore deposits. The project will provide a new set of tools to explore for gold-rich ore deposits in Australia and globally. By integrating geochemical studies with cutting-edge experiments carried out at three Australian universities in strategic partnership with industry, the outcomes of this project will provide much needed knowledge to predict the locations of large gold-rich deposits that are concealed beneath vast expanses of the Australian continent. The new results will translate into smarter exploration practice, significantly enhancing success in targeting ore deposits that are rich in high-value metal and display the smallest have a small environmental footprint, to underpin the sustainability of our nation into the future.

Geochemistry of ore metals at very high temperatures. The world’s largest copper and gold mines occur in extinct volcanoes around the Pacific Rim. Understanding how these essential metals are mobilised from magmas in the roots of volcanoes to become ore deposits and how to recognize where this has occurred is crucial in exploration for new deposits.

Cutting-edge electron probe microanalysis driving Western Australia’s resource geosciences. This project aims to provide a new generation electron microprobe, with advances in trace element mapping and cathodoluminescence analysis to enable superior characterisation of a wide range of materials. The overwhelming demand for electron probe microanalysis from research groups in Western Australia requires renewal of over-subscribed, ageing facilities to drive innovation and alleviate bottlenecks in ....Cutting-edge electron probe microanalysis driving Western Australia’s resource geosciences. This project aims to provide a new generation electron microprobe, with advances in trace element mapping and cathodoluminescence analysis to enable superior characterisation of a wide range of materials. The overwhelming demand for electron probe microanalysis from research groups in Western Australia requires renewal of over-subscribed, ageing facilities to drive innovation and alleviate bottlenecks in advanced geosciences multi-capability workflows. The electron probe will drive underpinning geoscience, resources science and economic geology, as well as support a broad range of disciplines and diverse fields, such as nanotechnology, microelectronics and aquatic sciences.Read moreRead less
Magnetite and metal-rich sulphides in arc magmas. Ascending magmas cool and crystallise a variety of minerals. Triggering sulfide deposition which hosts base and precious metals is a critical point in magma evolution. This research will explore the role of magnetite as this trigger and its potential as a tracer of this process.
Reconstructing the Beetaloo/Greater McArthur Basin System . This project aims to build a stratigraphic and water chemistry framework for the greater McArthur Basin—a rock system that covers northern Australia from WA to Queensland. This will be a vital resource for researchers and energy/mineral explorers. This project expects to develop novel sediment dating and isotopic proxies for salinity, redox and bioproductivity and use them to build a sequence stratigraphic framework of the basin. The ex ....Reconstructing the Beetaloo/Greater McArthur Basin System . This project aims to build a stratigraphic and water chemistry framework for the greater McArthur Basin—a rock system that covers northern Australia from WA to Queensland. This will be a vital resource for researchers and energy/mineral explorers. This project expects to develop novel sediment dating and isotopic proxies for salinity, redox and bioproductivity and use them to build a sequence stratigraphic framework of the basin. The expected outcome is a unique 3D lithological, geochronological and geochemical framework for the basin. Expected benefits include de-risked information for the petroleum and minerals industry, assisting northern Australia's resources economy, as well as insights into the development of our planet in deep time.Read moreRead less
Gold transport in aqueous versus organic fluids: Experimental data for describing ore-forming systems. In many hydrothermal ore-forming systems, the ore is associated with inclusions of both aqueous brine and organic liquid (petroleum). The conventional theory is that the metals are dissolved and transported to the deposit by the brine, but some researchers suggest that petroleum may fill this role. This project proposes to conduct an experimental and field-based study on the chemical behaviour ....Gold transport in aqueous versus organic fluids: Experimental data for describing ore-forming systems. In many hydrothermal ore-forming systems, the ore is associated with inclusions of both aqueous brine and organic liquid (petroleum). The conventional theory is that the metals are dissolved and transported to the deposit by the brine, but some researchers suggest that petroleum may fill this role. This project proposes to conduct an experimental and field-based study on the chemical behaviour of gold in aqueous-organic and organic fluid systems, to determine which type of liquid is more important for gold mobilisation in a competitive situation. This study will provide much-needed data for more accurate modelling of ore systems, furthering our understanding and facilitating mineral exploration. Read moreRead less

This project aims to reveal the potential for undiscovered economic deposits of rare earth elements within the Australian continent. Future supply of these elements underpins societies transition to clean energy and embrace of high-tech applications. The project expects to greatly enhance our knowledge of Australia’s endowment of rare earth element resources using an array of traditional and innovative geological research methods. Expected outcomes of this project include a greater understanding of how, where and when rare earth element orebodies form in the Earth's crust. This should provide significant benefits to exploring for––and discovering––new orebodies that are required to secure global critical metal supplies. Read moreRead less

Diamonds - a window into the ancient mantle: the origin of Earth's atmosphere and outgassing of the mantle. The project will provide a better understanding of the mantle source regions of diamonds and, in particular, homogeneity/heterogeneity of the source regions as a function of space and time - potentially of economic significance for diamond exploration. The project will investigate the noble gas compositions of a systematic selection of diamonds of different ages and from different parts of ....Diamonds - a window into the ancient mantle: the origin of Earth's atmosphere and outgassing of the mantle. The project will provide a better understanding of the mantle source regions of diamonds and, in particular, homogeneity/heterogeneity of the source regions as a function of space and time - potentially of economic significance for diamond exploration. The project will investigate the noble gas compositions of a systematic selection of diamonds of different ages and from different parts of the mantle. Together with carbon and nitrogen isotope systematics, this information will be used to better constrain models of Earth outgassing and the evolution of the Earth's atmosphere and mantle.Read moreRead less
