Reliable dating techniques are required to obtain precise ages for ancient crustal fluid flow. Current techniques suffer from inheritance and isotopic resetting, problems that are particularly pronounced in early Precambrian rocks. This project will employ new analytical techniques to date phosphate minerals recently identified as potentially important new chronometers of ancient fluid flow, providing the first precise tectonothermal history of the Archaean Pilbara Craton. The project will also establish the age of giant iron-ore deposits across the Hamersley Province, test the various models for iron-ore formation, and provide a minimum age for the oxidation of the Earth's surface.

Tectonic evolution and lode gold mineralisation in the Southern Cross district, Yilgarn Craton (Western Australia): a study of the meso- to Neoarchaean missing link. In the December quarter 2008, Gold export earnings increased by 2 per cent to $3.9 billion. Over the past 20 years and despite an increase in exploration expenditure to around $50 million per year, the discovery rates have been declining. Although the easy targets have been found, there remains considerable potential for future ma ....Tectonic evolution and lode gold mineralisation in the Southern Cross district, Yilgarn Craton (Western Australia): a study of the meso- to Neoarchaean missing link. In the December quarter 2008, Gold export earnings increased by 2 per cent to $3.9 billion. Over the past 20 years and despite an increase in exploration expenditure to around $50 million per year, the discovery rates have been declining. Although the easy targets have been found, there remains considerable potential for future major discoveries. This project addresses the pressing need for new data and improved exploration techniques to enable industry to target new discoveries. As the Southern Cross district is located in remote communities such discoveries also have major benefits for regional Australia.Read moreRead less
Deep Crustal Section Through a Late Archaean Orogen (Greenland): Archaean Crustal Sutures, Abyssal Peridotites and Gold. Did plate tectonics operate in Earth's early times - the Archaean (before 2500 million years ago)? This is important for understanding Australia's rich Archaean gold mineralisation. Using plate tectonics, young mountains like the European Alps formed when once distant continents collided. The project will investigate the origins of a deeply-eroded, superbly-exposed Archaean Gr ....Deep Crustal Section Through a Late Archaean Orogen (Greenland): Archaean Crustal Sutures, Abyssal Peridotites and Gold. Did plate tectonics operate in Earth's early times - the Archaean (before 2500 million years ago)? This is important for understanding Australia's rich Archaean gold mineralisation. Using plate tectonics, young mountains like the European Alps formed when once distant continents collided. The project will investigate the origins of a deeply-eroded, superbly-exposed Archaean Greenland mountain belt and its gold mineralisation. This is to establish whether it represents a deep section through an Archaean continent-continent collision formed via ancient plate tectonics and also to provide insight into Australia's important Archaean gold deposits and to produce models to help search for more gold.Read moreRead less

Cracking the sulfate isotopic composition problem in ancient hydrothermal systems: application of the Carbonate-Associated Sulfate (CAS) method. Successful exploration of the deep Earth for valuable ores requires better knowledge of ore formation conditions, to feed to predictive deposit models. Our work shows great promise of improving the quality of this raw data. Smarter ore deposit prediction would likely exert its influence over the next ten years, rather than be immediate. It will increase ....Cracking the sulfate isotopic composition problem in ancient hydrothermal systems: application of the Carbonate-Associated Sulfate (CAS) method. Successful exploration of the deep Earth for valuable ores requires better knowledge of ore formation conditions, to feed to predictive deposit models. Our work shows great promise of improving the quality of this raw data. Smarter ore deposit prediction would likely exert its influence over the next ten years, rather than be immediate. It will increase exploration efficiency, saving tens of millions of dollars currently devoted to unproductive exploration. Exploration and mining are conducted primarily in regional Australia, and a healthy mining industry is therefore directly benefits hinterland communities. It also benefits all Australians through the payment of royalties and contributions to Australia's GDP from mineral exports.Read moreRead less
