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
Molecular fossils, the evolution of Earth's early oceans and the origin of the oldest oil. Australia retains undiscovered oil reserves. We believe that a change in primitive marine life forms may have fundamentally changed the chemistry of the Earth's oceans and is responsible for the world's oldest oil reserves. While these reserves have been found, and successfully commercialised, overseas, similar reservoirs in Australia remain elusive. The project will develop and apply technologies based on ....Molecular fossils, the evolution of Earth's early oceans and the origin of the oldest oil. Australia retains undiscovered oil reserves. We believe that a change in primitive marine life forms may have fundamentally changed the chemistry of the Earth's oceans and is responsible for the world's oldest oil reserves. While these reserves have been found, and successfully commercialised, overseas, similar reservoirs in Australia remain elusive. The project will develop and apply technologies based on hydrocarbon biomarkers to help determine the oil-producing rock types of Precambrian sedimentary rocks. This allows us to estimate the oil's age and predict where petroleum reservoirs may be hidden. PhD students involved in the project will gain valuable knowledge about the link between changes in ecology and the carbon cycle.Read moreRead less

Increasing salinity of lakes is a critical problem for sustainable water supply in Australia. To comprehend the consequences of human-induced salinization, it is crucial to understand salt lakes at their most fundamental level. This project develops pioneering technologies to elucidate the microbial ecology and geochemistry of salt lakes in unprecedented detail. It will open new pathways to unravel how microbial ecosystems adapt to increasing salinization, and how they reacted to climate fluctuations in the past. Students will gain multidisciplinary skills in environmental genomics, proteomics and geochemistry, a unique combination that will become decisive for understanding and preserving ecosystems on our continent.Read moreRead less
Biomolecular chemical survival strategies of terrestrial extremophiles and the spectroscopic search for life on Mars. This project is aimed to place Australian research at the forefront of developments in the search for extraterrestrial life, the evolution of life on earth, and the design of new probes for the identification of microorganisms.

Palaeobiology of hydrothermal mineral deposits. Mineral deposits that formed at up to 150 degrees C record the history of micro-organisms referred to as hyperthermophiles. Current biological studies predict that such organisms are the most primitive known. Thus by studying these deposits we have the opportunity to uncover the earliest history of life on Earth, and to improve our understanding of ore deposition. Such deposits are also prime targets for the search for life and former life elsewher ....Palaeobiology of hydrothermal mineral deposits.

Current biological studies predict that such organisms are the most primitive known. Thus by studying these deposits we have the opportunity to uncover the earliest history of life on Earth, and to improve our understanding of ore deposition. Such deposits are also prime targets for the search for life and former life elsewhere in the Solar System, and the proposed research will contribute to that search.Read moreRead less
Organic geochemistry of the McArthur River hydrothermal deposit. Exploration for hydrothermal ore deposits in sedimentary basins has many problems because of the lack of any general agreement on the mechanisms of formation of major deposits. This proposed research will focus on the fundamental issue of the interaction of organic matter and mineralizing fluids in contributing to ore mineral deposition. Given that the McArthur River orebody is an exquisitely preserved example of a hydrothermal dep ....Organic geochemistry of the McArthur River hydrothermal deposit. Exploration for hydrothermal ore deposits in sedimentary basins has many problems because of the lack of any general agreement on the mechanisms of formation of major deposits. This proposed research will focus on the fundamental issue of the interaction of organic matter and mineralizing fluids in contributing to ore mineral deposition. Given that the McArthur River orebody is an exquisitely preserved example of a hydrothermal deposit it will thus enable a comprehensive organic geochemical investigation to elucidate the role of organic matter in ore formation. The outcomes will benefit the Australian mineral exploration industry by refining current ore genesis models.Read moreRead less
Reconstruction of anoxic and toxic conditions in Australian lakes and ancient oceans. Sustainable water quality is a critically important issue for Australia's economic and social development.

Sustainable water quality is a critically important issue for Australia's economic and social development. To be able to predict and plan the future of Australia's lakes and estuaries, it is crucial to understand their ecological past and to determine their state prior to and post-European settlement. This project develops and applies novel methodologies to reconstruct the history of cyanobacterial blooms, eutrophication and anoxia in Australian waterways. It will help to identify human impact on water quality. The new methodologies, applied to ancient sedimentary rocks, will also yield information about the effect of environmental changes on early life on Earth, enforcing Australia's position in the study of global geochemical cycles.Read moreRead less

Maintaining the quality of water and soil is a critically important issue for Australia's economic and social development. To be able to predict and plan the future of our natural assets, it is critical to understand their ecological past and their state before and after European settlement. We will utilize the new instrument to develop and apply innovative technologies providing Australia with new knowledge about the causes and effects of toxic cyanobacterial blooms, eutrophication, and contamination of reservoirs by bush-fires. The new facility will also supply advanced oil fingerprinting techniques to the petroleum industry minimizing exploration risk and increasing the chance of the discovery of new oil deposits.Read moreRead less
