Understanding the Thomson Orogen, a geological region which straddles the New South Wales and Queensland border, is critical for developing geodynamic models for the evolution of eastern Australia, and assessing resource potential. However, it lies under the Great Artesian Basin. This project focusses on ground truthing geophysical acquisition studies using drill core from a targeted drilling program, designed to maximise the available tectono-stratigraphic information. The outcome intends to be a 3D geological map of the region, which can be interrogated for mineral exploration targeting, and from which 4D evolutionary geodynamic models of eastern Australian can be integrated.Read moreRead less
Mechanisms of proxy uptake in biominerals. This project plans to combine nano-analytical and aquaculture methods to develop new models that improve the reliability of paleoclimate reconstructions. The compositions of shells and skeletal materials of marine invertebrates are essential archives for quantifying temperatures and environmental conditions before modern climate records began. However, their reliability relies on understanding their formation. Emerging knowledge from material sciences i ....Mechanisms of proxy uptake in biominerals. This project plans to combine nano-analytical and aquaculture methods to develop new models that improve the reliability of paleoclimate reconstructions. The compositions of shells and skeletal materials of marine invertebrates are essential archives for quantifying temperatures and environmental conditions before modern climate records began. However, their reliability relies on understanding their formation. Emerging knowledge from material sciences indicates that these biocarbonates form via transient precursors rather than direct precipitation from seawater, profoundly affecting their interpretation. This project plans to transfer this new understanding to the earth sciences using nanoscale analytical methods including in vitro geochemical partitioning experiments. This would enable realistic models for geochemical proxy behaviour to be developed, significantly improving paleoclimate interpretations and assessments of ocean acidification effects on marine calcifiers.Read moreRead less
The Origin of Australian Opal Deposits: Unlocking the Secrets of an Australian Icon. Opal is the National Gemstone of Australia. With over 95% of world's precious opal being mined in Australia, this precious mineral is not only one of our major export earners but also the life blood of many central Australian townships. Despite its economic significance and long history of mining little is known about the formation of opal. Consequently, exploration is still based on old-fashioned prospecting me ....The Origin of Australian Opal Deposits: Unlocking the Secrets of an Australian Icon. Opal is the National Gemstone of Australia. With over 95% of world's precious opal being mined in Australia, this precious mineral is not only one of our major export earners but also the life blood of many central Australian townships. Despite its economic significance and long history of mining little is known about the formation of opal. Consequently, exploration is still based on old-fashioned prospecting methods rather than on genetic exploration models that have made base metal exploration so successful. The aim of this project is to investigate the processes controlling the formation of Australian opal and to use this information to construct an exploration model that will lead to more effective and efficient exploration methods.Read moreRead less
The behaviour of geochemical tracers during differentiation of the Earth. This project is aimed at providing fundamental data which Earth Scientists will use to understand the processes by which the Earth separated into its chemically-distinct layers (core, mantle, crust, atmosphere, oceans) and to determine the nature of the continuing interactions between the surface environment in which we live and the deep interior. It will provide training in modern high temperature-high pressure materials- ....The behaviour of geochemical tracers during differentiation of the Earth. This project is aimed at providing fundamental data which Earth Scientists will use to understand the processes by which the Earth separated into its chemically-distinct layers (core, mantle, crust, atmosphere, oceans) and to determine the nature of the continuing interactions between the surface environment in which we live and the deep interior. It will provide training in modern high temperature-high pressure materials-science techniques for Ph.D. students and postdoctoral researchers. This will provide Australia with Earth Scientists who have both traditional skills and the ability to work with Materials Scientists on the synthesis of novel materials under extreme conditions.Read moreRead less

Australia has an enviable reputation as a leading innovator in geochronological and geochemical studies and this research will reinforce that standing. The outcomes will promote a better understanding of Australia's arid continent, contribute to studies of global climate change, and provide new insights into the response of ecosystems to such events. In these ways, the project addresses directly our current national research priorities 'water - a critical resource', 'responding to climate change and variability' and 'the sustainable use of Australia's biodiversity'.Read moreRead less
Climate dynamics of the Australian monsoon and its re-establishment following the last glacial maximum. The dynamics and linkages among elements of the global climate system (eg. North Atlantic - Antarctica- tropics) are poorly understood, particularly near the Last Glacial Maximum about 20,000 years ago. For the interval 80,000 to 10,000 years ago, we propose to produce a high-resolution environmental record(every 80 years) and dynamical model, using lacustrine sediments from the Gulf of Carpen ....Climate dynamics of the Australian monsoon and its re-establishment following the last glacial maximum. The dynamics and linkages among elements of the global climate system (eg. North Atlantic - Antarctica- tropics) are poorly understood, particularly near the Last Glacial Maximum about 20,000 years ago. For the interval 80,000 to 10,000 years ago, we propose to produce a high-resolution environmental record(every 80 years) and dynamical model, using lacustrine sediments from the Gulf of Carpentaria. We seek information on the intensity and possible disappearance of the monsoon, tropical atmospheric teleconnections with millennial-scale ice-rafting episodes at higher latitudes, and influence of aboriginal vegetation-burning on climate. Such links, if found, would profoundly alter our understanding of all tropical environments and their management.Read moreRead less
Rehydration of the lower crust, fluid sources and geophysical expression. This project aims to explore a long-standing mystery: the origin of deep crustal electrical conductors detected by magnetotelluric imaging of tectonically stable crust. These features occur in cratons of all ages, and commonly cross cut structures and lithologies. This project aims to investigate the hypothesis that such features are the record of ancient deep crustal fluid flow, which modified the rock electrical properti ....Rehydration of the lower crust, fluid sources and geophysical expression. This project aims to explore a long-standing mystery: the origin of deep crustal electrical conductors detected by magnetotelluric imaging of tectonically stable crust. These features occur in cratons of all ages, and commonly cross cut structures and lithologies. This project aims to investigate the hypothesis that such features are the record of ancient deep crustal fluid flow, which modified the rock electrical properties. Using an exceptionally exposed natural laboratory preserving large-scale rehydration of anhydrous lower crust, the project plans to determine the source of fluids and the compositional changes they induced. It then plans to experimentally determine changes in resistivity induced by fluid flow and use that data to model the magnetotelluric response at crustal scale.Read moreRead less
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.

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
