The research outlined in this proposal will place Australia at the forefront of Mars exploration research. It will lead to the development of new approaches for the analysis of minerals formed by low temperature water-rock interaction and for the interpretation of geochronological results obtained from supergene minerals. The new analytical approaches developed in this project will have direct application in the study of the paleoclimatological and environmental evolution of Earth and Mars. It will also result in improved understanding of environmental and landscape evolution in Australia, helping to reach the objectives of an Environmentally Sustainable Australia, a national research priority.Read moreRead less
Uncoupling past salinity and temperature signals in the Indo-Pacific Warm Pool: implications for climate change in the Australian region. The tropical oceans and in particular the Indo-Pacific Warm Pool, immediately to Australia's north, play a key role in modulating global and Australian climate through El-Niño and related phenomena. Using a new microanalysis approach to analyse individual foraminifera from deep-sea cores, we will reconstruct past salinity and temperature variability within the ....Uncoupling past salinity and temperature signals in the Indo-Pacific Warm Pool: implications for climate change in the Australian region. The tropical oceans and in particular the Indo-Pacific Warm Pool, immediately to Australia's north, play a key role in modulating global and Australian climate through El-Niño and related phenomena. Using a new microanalysis approach to analyse individual foraminifera from deep-sea cores, we will reconstruct past salinity and temperature variability within the Warm Pool, and determine changing rainfall patterns and, ENSO and monsoon behaviour under climate conditions that lie outside modern records. This information is vital for understanding past climate and predicting the future intensity and frequency of El-Niño related drought and wet cycles in Australia.Read moreRead less
Carbon and Hydrogen in Melts and Fluids in Planetary Interiors. The Australian community will benefit by the ownership of widely used high impact research in published earth science. This research defines the melting behaviour of silicate-rich materials (terrestrial planets, rocky-moons, meteorites) within the solar system.

The Australian community will benefit by the ownership of widely used high impact research in published earth science. This research defines the melting behaviour of silicate-rich materials (terrestrial planets, rocky-moons, meteorites) within the solar system. The research will be required for interpretation of Martian samples and will help to ensure that Australian laboratories participate in 21st Century investigations of the Solar System by virtue of their leading roles in understanding volcanism and melting behaviour at high pressures and under variable oxidation states. The research will address a national priority in sustainability of earth resources i.e. knowledge underpinning formation of Australian mineral resources.Read moreRead less
Order-disorder behaviour in Bi-tellurides: a tool to monitor gold scavenging by Bi-Te melts. This project addresses a group of minerals (bismuth tellurides) that are often part of the exotic assemblages present in gold deposits, yet their potential to model the gold-forming processes is only recently apparent. These minerals also have the capacity to record their genetic history due to crystal modularity. Materials scientists target the analogous synthetic compounds because of the same structura ....Order-disorder behaviour in Bi-tellurides: a tool to monitor gold scavenging by Bi-Te melts. This project addresses a group of minerals (bismuth tellurides) that are often part of the exotic assemblages present in gold deposits, yet their potential to model the gold-forming processes is only recently apparent. These minerals also have the capacity to record their genetic history due to crystal modularity. Materials scientists target the analogous synthetic compounds because of the same structural modularity for applications in nanotechnology. The dataset on the mineral compounds, using the geological environment as a natural laboratory, will serve materials science research, as much as delivering key information relevant to understanding the reasons for gold enrichment in economically important types of ores.

The Impact of Changing Climatic Conditions inferred from the Isotope Abundances of Trace Metals in Global Ice Sheets and Glaciers. In this project Greenland and Antarctic ice-cores more than 3 km long will be used to investigate climatic variation extending back more that 4 complete glacial cycles. Some of these ice-cores include sections of refrozen water formed from sub-glacial Antarctic lake water. This project will use naturally occurring lead and strontium isotopic tracers to fingerprint ....The Impact of Changing Climatic Conditions inferred from the Isotope Abundances of Trace Metals in Global Ice Sheets and Glaciers. In this project Greenland and Antarctic ice-cores more than 3 km long will be used to investigate climatic variation extending back more that 4 complete glacial cycles. Some of these ice-cores include sections of refrozen water formed from sub-glacial Antarctic lake water. This project will use naturally occurring lead and strontium isotopic tracers to fingerprint impurities in the ice, because they have the potential to simultaneously signal the timing and location of past episodes of climate change. This will lead to an improvement in our understanding of the processes that cause these changes.Read moreRead less
Magmatism, Metamorphism and Mineralisation: The Development of an Isotopic and Geochemical Framework for the Curnamona Cu-Au Province. Recent advances have highlighted the potential significance of the Olary Domain in the Curnamona Province in southern Australia as an important Proterozoic copper-gold district. However, an outstanding problem yet to be solved is the interplay between mineralisation, granitic magmatism and the metamorphic history of the Province.

Recent advances have highlighted the potential significance of the Olary Domain in the Curnamona Province in southern Australia as an important Proterozoic copper-gold district. However, an outstanding problem yet to be solved is the interplay between mineralisation, granitic magmatism and the metamorphic history of the Province. This multi-disciplinary project will use isotopic and geochemical tools to develop an integrated geologic framework within which to view mineralisation. The outcomes will enhance the prospectivity of the region and make an important contribution to the globally relevant question of controls on Proterozoic copper-gold systems.Read moreRead less
