This interdisciplinary project links geochemistry with crustal-scale fluid migration, aiming to improve mineral exploration success for orogenic gold deposits. In doing so, it intends to provide a more holistic view of gold deposit genesis. This project plans to focus on the Victorian goldfields, which have world-class historic gold production, an existing seismic transect, and a geologic setting that will address key problems in gold deposit genesis. A series of modelling techniques will be used to marry structural and geochemical aspects of gold deposit formation at a scale that has not been previously attempted.Read moreRead less
Physical and Chemical Constraints of Fluid Activated Processes During the Polyphase Tectonic Evolution of the Olary Domain, S.A. The Olary Domain, eastern South Australia, underwent several phases of deformation and metamorphism. These events mobilised fluids leading, amongst other features, to the formation of breccia bodies and mineral deposits. The complex nature of the geological evolution of the region obscures relationships of fluid migration to the structural history. Fluid inclusion stud ....Physical and Chemical Constraints of Fluid Activated Processes During the Polyphase Tectonic Evolution of the Olary Domain, S.A. The Olary Domain, eastern South Australia, underwent several phases of deformation and metamorphism. These events mobilised fluids leading, amongst other features, to the formation of breccia bodies and mineral deposits. The complex nature of the geological evolution of the region obscures relationships of fluid migration to the structural history. Fluid inclusion studies and stable isotope analyses combined with structural analyses on micro to macro scales shall establish links between the thermal and structural evolution of the area. This will provide insigth into the scale and physico-chemical characteristics of fluids and mineralising processes an relate these to the tectono-thermal history.Read moreRead less

This project will use a multi-disciplinary approach to understand the geology, geochemistry and genesis of the syndeformational, structurally-controlled, sediment-hosted copper mineralisation at the Mt Oxide deposit, Queensland. Copper deposits, like Mt Oxide, are an important exploration target in sedimentary basins but their characteristics and formation are poorly understood. Discovery of further sediment-hosted Cu deposits is imperative as Australia's industrial competitivness in exploration and mining depends on the discovery of new ore depsoits. This project specifically addresses the need for better genetic and exploration models for copper deposits concealed within ancient, deformed sedimentary sequences in Australia and overseas.Read moreRead less
Origin and setting of Congolese-type Cu deposits. This project aims to understand the genesis of the giant sediment-hosted Cu ore deposits of the Congolese Copperbelt, and their relationship to the enclosing strata. We will use selected study areas within the correlative Neoproterozic basin successions in Australia, which are well exposed and covered by modern geoscientific datasets, as analogues for the poorly exposed Congolese system. Once this is achieved, we will combine the results with tho ....Origin and setting of Congolese-type Cu deposits. This project aims to understand the genesis of the giant sediment-hosted Cu ore deposits of the Congolese Copperbelt, and their relationship to the enclosing strata. We will use selected study areas within the correlative Neoproterozic basin successions in Australia, which are well exposed and covered by modern geoscientific datasets, as analogues for the poorly exposed Congolese system. Once this is achieved, we will combine the results with those of a previous ARC linkage project on the nearby Zambian Copperbelt, to provide the first integrated model of the worlds largest sedimentary Cu system.Read moreRead less

The remote Musgrave Province is one of Australia's prime areas of mineral exploration interest, with about 30 companies holding more than 120 leases over the region. A major factor determining the economic prospectivity of a terrane is the availability of high quality geoscientific data. This project will produce pre-competitive structural, petrological, isotopic, geochemical and geophysical datasets for the west Musgrave Province that will rival or surpass that available for other regions of Australian crust. This project directly aligns with the National Research Priority goal, developing deep Earth resources, and will reduce the risk to mineral explorers and facilitate economic development within the Ngaanyatjarra Native Title Lands of Western Australia.Read moreRead less
