Add mountains and shake: plate boundary fault and earthquake patterns. This project aims to determine the fundamental physical processes that link topography, seismic shaking and volcanism to the evolution of seismogenic fault networks in obliquely convergent (transpressional) plate boundary settings. We will combine detailed field and remote sensing-based structural analyses in transpressional mountain belts with advanced laboratory analogue and numerical experiments to evaluate: 1) how bursts ....Add mountains and shake: plate boundary fault and earthquake patterns. This project aims to determine the fundamental physical processes that link topography, seismic shaking and volcanism to the evolution of seismogenic fault networks in obliquely convergent (transpressional) plate boundary settings. We will combine detailed field and remote sensing-based structural analyses in transpressional mountain belts with advanced laboratory analogue and numerical experiments to evaluate: 1) how bursts of strong seismic shaking perturb fault zone evolution through time; 2) the contribution of topography and gravitation loading to fault interactions and earthquake generation; and 3) feedbacks between fault network development, the spatial distribution of volcanic centres, seismic shaking and ore deposits.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. 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

The project aims to develop technologies enabling rapid informed decision-making related to the management of natural resources, including critical metals, copper and water. This new technology will support a greener future, securing our energy future, our access to clean water and reduce the mining footprint. Expected outcomes include an enhanced capability in interoperable, integrated three-dimensional geological and geophysical modelling in order to predictively characterise sub-surface geology. The outcome will be an open-source forecasting dashboard enabling decision making while considering underlying risk related to resource extractions and management with significant benefits to the Australian society (lower emissions, clean water).Read moreRead less
The lost ocean of eastern Australia and its critical metals endowment. This project aims to unravel the tectonic origin and economic potential of ultramafic rocks (rocks which host elevated concentrations of nickel, cobalt, chromium, and platinum-group elements). Such rocks are outcropping in eastern Australia along a contorted ~1500 km long belt that may record relics of an ancient ocean. Through detailed mapping and cutting-edge analytical techniques, the project is expected to fill a crucial ....The lost ocean of eastern Australia and its critical metals endowment.

Such rocks are outcropping in eastern Australia along a contorted ~1500 km long belt that may record relics of an ancient ocean. Through detailed mapping and cutting-edge analytical techniques, the project is expected to fill a crucial knowledge gap in Australian tectonics, while providing information on ore mineralisation. The expected outcomes, including new tectonic models unveiling the scale, geometry, and economic potential of the ultramafic bodies, could benefit critical mineral exploration, carbon storage solutions, and geoecology conservation.Read moreRead less

This joint Melbourne-Curtin facility seeks to generate ultra-precise age data from ever smaller and younger samples, such as minute particles from space return missions and tiny inclusions in diamonds. The facility is expected to revolutionise noble gas dating techniques, resulting in new knowledge on solar system genesis, hominid evolution, indigenous migrations, palaeo-climate change, natural hazards and ore deposit formation, while further enhancing Australia’s international leadership and competitive advantage in the discipline.

This project will deliver the most comprehensive investigation of Earth’s oldest known river/lake deposits, uniquely preserved in 2.8 billion-year-old rocks in Western Australia. Using the candidate’s expertise in field investigation in combination with a cutting-edge analytical approach, the project will produce a detailed reconstruction of the ancient lake environment. Similar settings will be explored by NASA's upcoming Mars 2020 rover mission at it's landing site in Jezero Crater. Mission data will be analysed by the candidate, who will guide the selection of samples and address the overarching question of whether microbal life ever existed on Mars.Read moreRead less

This year sees the highly anticipated return of the Hayabusa2 spacecraft to Woomera carrying samples of the asteroid Ryugu. This is only the fifth extraterrestrial sample return mission in history. The research team has been invited to participate in the preliminary examination which will take place in Japan in early 2021. The investigators have developed unique analytical skills that allow measurement of small amounts of rock for oxygen isotope compositions at unprecedented precision. This project aims to characterise a suite of carbonaceous chondrites, which appear to be the best match to Ryugu, and therefore will provide the exemplar data to understand the provenance of Ryugu, and place it in the context of solar system materials.

Role of water in earth and planetary evolution. This project aims to understand the role of water in the building of our solar system, Mars and Earth. Surprisingly little is known about key issues surrounding the origin of water and its subsequent recycling on Earth.

This project aims to understand the role of water in the building of our solar system, Mars and Earth. Surprisingly little is known about key issues surrounding the origin of water and its subsequent recycling on Earth. This project will use new techniques for measuring low abundances of water along with oxygen isotopes, to measure water abundances and oxygen isotopes in meteorites and terrestrial rocks to establish how water was delivered to Earth and to understand how water is geologically recycled. This is expected to have direct bearing on where and how Earth's water originated, how water is retained in mantle and crustal minerals and it will have broad implications for understanding volcanic hazards and formation of ore deposits. This will lead to a new capability for combined water and oxygen isotope analysis in Australian geoscience leading to technological development and commercialisation of instrumentation.Read moreRead less
