Rapid process development for the assembly of lightweight metal components. This project aims to develop a new quality monitoring system and inverse method for identifying parameters of welding structures for automotive applications. The outcomes may assist automotive industries in improving process quality management and product performance of weld structures.
Developing an environmentally friendly, low cost solution to reduce wear and improve productivity in metal forming . Tool wear is an increasing problem for automotive manufacturers, resulting in significant loss of manufacturing efficiency. This project will provide new understanding of tool wear, innovative active monitoring systems and novel environmentally friendly lubricants to reduce tool wear.
Understanding the stratigraphic and structural architecture of late Archean basins and the context of their gold deposits. Gold mined from Archean rocks contributed $4.0 billion to Australia's export income in 2006 and provided the backbone of support for many remote communities. However, production has fallen 40% since 1997 and will be exhausted within 15 years unless major new discoveries are made. The potential to find additional gold deposits remains high, but urgently requires new data and ....Understanding the stratigraphic and structural architecture of late Archean basins and the context of their gold deposits. Gold mined from Archean rocks contributed $4.0 billion to Australia's export income in 2006 and provided the backbone of support for many remote communities. However, production has fallen 40% since 1997 and will be exhausted within 15 years unless major new discoveries are made. The potential to find additional gold deposits remains high, but urgently requires new data and improved exploration techniques to assist in their discovery. The results of this integrated multidisciplinary project will help to arrest the declining discovery rate and thereby sustain this important Australian industry.Read moreRead less
Deformational controls on the dynamics of fluid flow, hydrothermal alteration and gold mineralisation, Argo Gold deposit, WA. Detailed structural analysis, combined with major and trace element geochemistry and stable isotope geochemistry, will be used to explore the 3D evolution of fluid pathways and their relationship to growth of shear zones, vein networks and alteration patterns in the Argo shear-hosted gold deposit. The research will be used to (1) maximise the efficiency of resource defini ....Deformational controls on the dynamics of fluid flow, hydrothermal alteration and gold mineralisation, Argo Gold deposit, WA. Detailed structural analysis, combined with major and trace element geochemistry and stable isotope geochemistry, will be used to explore the 3D evolution of fluid pathways and their relationship to growth of shear zones, vein networks and alteration patterns in the Argo shear-hosted gold deposit. The research will be used to (1) maximise the efficiency of resource definition and extraction, (2) refine resource exploration models, (3) explore the dynamics of gold mineralisation processes in shear zones, and (4) advance understanding of how coupling between deformation, fluid flow, and fluid-rock reaction influence the mechanical behaviour of the Earth's crust.Read moreRead less
Exploration potential and implications for stress transfer modelling in fault-related mineral deposits. Following our success in the application of stress transfer modelling (STM) techniques to understand the clustered distribution of upper crustal, Archean gold deposits within crustal scale fault systems, this project seeks to test and develop the application of STM in (1) gold systems formed below the crustal seismogenic regime, (2) for deposit-scale targeting, and (3) in a range of fault-re ....Exploration potential and implications for stress transfer modelling in fault-related mineral deposits. Following our success in the application of stress transfer modelling (STM) techniques to understand the clustered distribution of upper crustal, Archean gold deposits within crustal scale fault systems, this project seeks to test and develop the application of STM in (1) gold systems formed below the crustal seismogenic regime, (2) for deposit-scale targeting, and (3) in a range of fault-related mineral deposits other than Archaean gold systems. The project will also develop methods to evaluate the combined roles of co-seismic stress transfer and post-seismic fluid redistribution in influencing deposit distribution. The approach provides a new conceptual framework in which to develop exploration strategies for deep earth resources.Read moreRead less
Prospectivity of late Archean basaltic and gabbroic rocks associated with major gold and base-metal deposits. This project will establish a new set of criteria for the discovery of hidden deposits of gold, lead, zinc, copper and silver in rock aged between 2.8 and 2.6 billion years old. In 2009, the mining of these deposits contributed $5.5 billion dollars to Australia’s export earnings and provided the financial backbone for many regional communities.
Development and Application of Stress Transfer Modelling for Area Selection in Mesothermal Gold Systems. Many mesothermal gold systems are hosted by low displacement faults and shear zones which develop adjacent to high displacement, crustal-scale faults and shear zones. By analogy with modern, seismogenic fault systems, the gold-hosting structures are interpreted as aftershock arrays whose formation is related to stress redistribution and fluid flow after major slip events on high displacement ....Development and Application of Stress Transfer Modelling for Area Selection in Mesothermal Gold Systems. Many mesothermal gold systems are hosted by low displacement faults and shear zones which develop adjacent to high displacement, crustal-scale faults and shear zones. By analogy with modern, seismogenic fault systems, the gold-hosting structures are interpreted as aftershock arrays whose formation is related to stress redistribution and fluid flow after major slip events on high displacement faults. This project will test and develop Coulomb stress transfer modelling techniques, currently used for aftershock risk assessment, for predicting the distribution of low displacment, gold-hosting structures around crustal-scale shear systems. The technique is expected to provide a powerful tool to assist area selection in fault-related epigenetic ore systems.Read moreRead less
Where to find giant porphyry and epithermal gold and copper deposits. This project will determine when and where giant gold or copper deposits should form, consolidating links with Indonesia, and using South East Asia as a vast natural laboratory in which to examine the effect of large-scale tectonic processes. The project will produce a four-dimensional virtual exploration toolkit to show how to apply the methods.
Hydrothermal remobilisation of base metals and platinum group elements in magmatic nickel deposits. Magmatic nickel sulphide deposits are highly valuable but extremely challenging exploration targets, thought to lack the distinctive geochemical haloes that allow small targets to be identified from sparse drilling. The project will test the potential of hydrothermal remobilisation of nickel, cobalt and platinum group elements to create broad alteration haloes.
Development of biosensors and bioindicators for gold exploration and processing in Australia. In times of increasing demand for gold and shrinking rates of discovery in Australia, biosensor and bioindicator techniques deliver significant advantages to the Australian mining industry and allow it to retain its international competiveness. The new understanding of the biogeochemical behaviour of gold in soils and other weathered materials developed in a previous ARC Linkage Project enables the deve ....Development of biosensors and bioindicators for gold exploration and processing in Australia. In times of increasing demand for gold and shrinking rates of discovery in Australia, biosensor and bioindicator techniques deliver significant advantages to the Australian mining industry and allow it to retain its international competiveness. The new understanding of the biogeochemical behaviour of gold in soils and other weathered materials developed in a previous ARC Linkage Project enables the development of biosensor and bioindicator technology that will allow mineral explorers to differentiate mineralised from non-mineralised zones using specific (meta) genomic community responses. The new technology will provide cost-efficient and environmentally sustainable techniques for improving exploration success and optimising ore processing.Read moreRead less
