Low-grade metamorphic phosphate geochronology: High-precision dating of ancient crustal fluid flow, hydrothermal mineralisation and the "Great Oxidation Event". 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 potent ....Low-grade metamorphic phosphate geochronology: High-precision dating of ancient crustal fluid flow, hydrothermal mineralisation and the "Great Oxidation Event". 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.

Summary
Western Australia Palaeomagnetic and Rock-magnetic Facility. The WA Palaeomagnetic and Rock-magnetic Facility is an essential piece of infrastructure for geoscience developments in WA and Australia in general. It not only serves the needs of the scientific community, but also supports resource-related projects sponsored by government and the resource industries, and serves the educational needs of postgraduate, undergraduate, and school students. Upgrading of the WA facility will enhance the res ....Western Australia Palaeomagnetic and Rock-magnetic Facility. The WA Palaeomagnetic and Rock-magnetic Facility is an essential piece of infrastructure for geoscience developments in WA and Australia in general. It not only serves the needs of the scientific community, but also supports resource-related projects sponsored by government and the resource industries, and serves the educational needs of postgraduate, undergraduate, and school students. Upgrading of the WA facility will enhance the research capacity of the WA geoscience community and maintain its international position in tectonic, palaeogeographic, and palaeoclimatic studies, and in ore genesis research.Read moreRead less
The early evolution of the Earth system from multiple sulfur isotope records of sediments and seafloor mineral systems. This project addresses the early evolution of the Earth system that is one of the most important questions in Earth Sciences. It will use Australia's unique rock record and analytical techniques developed in Australia in collaboration with leading international researchers. The National Research Priority area 'An environmentally sustainable Australia: developing deep Earth reso ....The early evolution of the Earth system from multiple sulfur isotope records of sediments and seafloor mineral systems. This project addresses the early evolution of the Earth system that is one of the most important questions in Earth Sciences. It will use Australia's unique rock record and analytical techniques developed in Australia in collaboration with leading international researchers. The National Research Priority area 'An environmentally sustainable Australia: developing deep Earth resources' will benefit through the development of better exploration models for Archaean submarine metal deposits. Students will obtain a high level understanding of the early Earth system, ore deposits, stable isotope and transition metal geochemistry, which are directly applicable in both pure and applied research and mineral exploration.Read moreRead less
