Four dimensional lithospheric evolution and controls on mineral system distribution in Neoarchean to Paleoproterozoic terranes. This project will resolve important questions about the links between the evolution and preservation of continents and important mineral deposits in Australia and West Africa between 2.7 and 1.8 billion years ago. The results will improve the understanding of a key period of Earth history and make a major contribution to mineral exploration.

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. 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 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
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
