Magmatic response to slab deformation and implications to ore formation. The uneven distribution of ore deposits in magmatic arcs is poorly understood. This project aims to provide new strategies for more effective mineral targeting by testing the hypothesis that anomalous magmatism enriched in metals reflects particular styles of deformation, such as tears in subducting slabs. We will use geophysical modelling to constrain slab structure along the northern boundary of the Australian plate, and ....Magmatic response to slab deformation and implications to ore formation. The uneven distribution of ore deposits in magmatic arcs is poorly understood. This project aims to provide new strategies for more effective mineral targeting by testing the hypothesis that anomalous magmatism enriched in metals reflects particular styles of deformation, such as tears in subducting slabs. We will use geophysical modelling to constrain slab structure along the northern boundary of the Australian plate, and geochemical data to establish spatio-temporal links with anomalous magmatism and ore deposits. By identifying the geochemical fingerprint of tear-related magmatism, outcomes are expected to benefit geoscience research and mineral exploration by providing context to similar rock associations in mineral-rich provinces.Read moreRead less
Evolution of sub-arc mantle oxidation state over Earth’s history. This project aims to determine how the oxidation state of the Earth's mantle has changed throughout geologic history in response to recycling of sulfur, carbon and iron though subduction zones, and how this has influenced mineral deposit formation. The expected outcome is a holistic model that ties evolution of the Earth's biosphere to geochemical changes in the deep Earth that control mineral deposit formation.

The expected outcome is a holistic model that ties evolution of the Earth's biosphere to geochemical changes in the deep Earth that control mineral deposit formation. By improving our understanding of how, where, when and why mineral deposits formed, this project should provide improvements in mineral exploration strategy, and thus benefits to Australia's economy.Read moreRead less

Summary
Linking Australia’s basement and cover mineral systems . The aim of this research is to use revolutionary new mineral-dating techniques to test the hypothesis that low-temperature fluids can transport metals from Australia's richly endowed geological basement to form new mineral deposits in the sedimentary basins that cover most of the continent. Sedimentary-hosted mineral systems are the largest source of the critical metal cobalt and the second largest source of copper on Earth. These two meta ....Linking Australia’s basement and cover mineral systems . The aim of this research is to use revolutionary new mineral-dating techniques to test the hypothesis that low-temperature fluids can transport metals from Australia's richly endowed geological basement to form new mineral deposits in the sedimentary basins that cover most of the continent. Sedimentary-hosted mineral systems are the largest source of the critical metal cobalt and the second largest source of copper on Earth. These two metals are essential to developing the green energy infrastructure and technologies that underpin a net zero economy. The expected outcomes are a detailed record of paleo-fluid flow and metal cycling in Australia's highly prospective sedimentary basins. Read moreRead less
Exploration targeting from next-generation volcanic facies reconstruction. The project aims to develop new innovative image analysis techniques to reconstruct the architecture of the volcanic host at four highly prospective hydrothermal-magmatic ore deposits, and investigate the properties of rocks that favour high-grade ore mineralisation.

The project aims to develop new innovative image analysis techniques to reconstruct the architecture of the volcanic host at four highly prospective hydrothermal-magmatic ore deposits, and investigate the properties of rocks that favour high-grade ore mineralisation. Expected outcomes of this project include next-generation automated techniques for volcanic facies analysis, and predictions of where hydrothermal alteration is most prospective for mineralisation. Both outcomes are relevant to the discovery of volcanic-hosted mineralisation globally. This project will provide significant benefit to the Australian mining industry by diversifying ore exploration strategies in the Australian crust, and will train the next generation of explorers.Read moreRead less

Fluid chemistry and critical mineral enrichment in salty metamorphic belts. Several geological regions in Australia are worth billions of dollars to our economy in their contained copper-goldcobalt and uranium-rare earth element mineral deposits. These regions will continue to be important to Australia as the world transitions to a renewable energy economy because they can provide some of the most critical metals needed for that transition: Cu, Co, rare earth elements.

Several geological regions in Australia are worth billions of dollars to our economy in their contained copper-goldcobalt and uranium-rare earth element mineral deposits. These regions will continue to be important to Australia as the world transitions to a renewable energy economy because they can provide some of the most critical metals needed for that transition: Cu, Co, rare earth elements. This project aims to provide a fundamental quatitative understanding of the geological processes that form these deposits. We will conduct experiments to generate quantitative models of the metamorphic and structural processes that control the liberation and migration of highly saline fluids, which are ideal for transporting a large range of metals.Read moreRead less

This project expects to generate new knowledge on the stability of detrital accessory minerals in the sedimentary cycle using observations from natural rocks and laboratory experiments. Expected outcomes include an assessment of the accessory minerals that are best suited to exploration vectoring studies in sedimentary basins. This should provide significant benefits to government and industry by improving mineral exploration methods and also has implications for geochronology and provenance studies.Read moreRead less

Summary
Critical metal fluid migration in shear zones during tectonic switches. This project aims to investigate why critical metal ore deposits form in inverted shear zones, which are zones of deformation that result from tectonic plates moving away from then towards each other. Numerical modelling of inverted shear zones will reveal drivers of ore fluid migration and will be combined with investigation of mineralised and non-mineralised inverted shear zones. This project will generate a new understand ....Critical metal fluid migration in shear zones during tectonic switches.

Numerical modelling of inverted shear zones will reveal drivers of ore fluid migration and will be combined with investigation of mineralised and non-mineralised inverted shear zones. This project will generate a new understanding of how inverted shear zones pump fluids through rocks to cause enrichment and ore deposition. This type of deposit is common in Queensland and the expected outcomes are improved exploration models, leading to discovery of new ore deposits, which is pivotal as the global demand for critical metals increases.Read moreRead less

We aim at enabling mineral resource discoveries by calibrating geophysical surveys using geochemical and petrophysical properties measured on mantle samples brought to the surface by recent volcanoes. National geophysical surveys deliver images of geophysical gradients in the deeper part of the Australian continent. The interpretation of these gradients in geological terms and in terms of economic mineral systems is the key to unlock deep exploration success. This project will turn Australia’s investment in National geophysical surveys into new discoveries of base metals. The benefit stems from enabling the transition to a clean economy which requires a much broader range of critical minerals and a larger quantity of base metals.Read moreRead less
