Crustal-Scale Fluid Flow in Deep Intracontinental Settings: Conditions, Sources and Deformational Responses. Fluids are important agents of heat and mass transport in the Earth's crust. They play a key role in the mobilisation of metals and as such play a crucial role in the generation of ore deposits. The outcomes of this project will result in a greater understanding of the mechanisms and sources of fluid generation and mobilisation in deep-crustal settings. These outcomes can be related direc ....Crustal-Scale Fluid Flow in Deep Intracontinental Settings: Conditions, Sources and Deformational Responses. Fluids are important agents of heat and mass transport in the Earth's crust. They play a key role in the mobilisation of metals and as such play a crucial role in the generation of ore deposits. The outcomes of this project will result in a greater understanding of the mechanisms and sources of fluid generation and mobilisation in deep-crustal settings. These outcomes can be related directly to the understanding of the controls on the transport and deposition of metals and hence the formation of mineral resources which are vital to maintaining a strong Australian economy.Read moreRead less
Biogeochemical characterisation of Archaean microfossils, biomarkers and organic matter: Probing the nature and diversity of early life on Earth. Recognizing biological signatures in ancient rocks poses the single greatest challenge to our understanding of the origin and evolution of life. This Project will use new advanced technology to reveal when and where life first appeared and assess its impact on the environment, atmosphere and climate. Results are essential for understanding the transfor ....Biogeochemical characterisation of Archaean microfossils, biomarkers and organic matter: Probing the nature and diversity of early life on Earth. Recognizing biological signatures in ancient rocks poses the single greatest challenge to our understanding of the origin and evolution of life. This Project will use new advanced technology to reveal when and where life first appeared and assess its impact on the environment, atmosphere and climate. Results are essential for understanding the transformation of our planet into a suitable habitat for humankind. The work will place Australia among world leaders in one of the most exciting topics of current scientific research, raising Australia's reputation in this high profile and competitive field. The Project tackles profound questions and seeks to attract, inspire and train future scientists in an ideal location and research environment.Read moreRead less
Stable isotopic studies and isotopic dating, Woodleigh Impact Structure, Western Australia: implications for the Late Devonian mass extinction. The 120 km diameter Woodleigh impact structure in the Carnarvon Basin, Western Australia is the third largest Phanerozoic impact structure. K-Ar dating of impact-induced alteration minerals indicates a Late Devonian age for Woodleigh. The precise timing of impact, nature of the impacting body and processes responsible for redistribution of meteoritic com ....Stable isotopic studies and isotopic dating, Woodleigh Impact Structure, Western Australia: implications for the Late Devonian mass extinction. The 120 km diameter Woodleigh impact structure in the Carnarvon Basin, Western Australia is the third largest Phanerozoic impact structure. K-Ar dating of impact-induced alteration minerals indicates a Late Devonian age for Woodleigh. The precise timing of impact, nature of the impacting body and processes responsible for redistribution of meteoritic components will be investigated using a range of analytical methodologies. A search will be made for impact-related sedimentary deposits to see if an extraterrestrial component can be identified and correlated with Woodleigh. The expected outcome is proof of an impact-extinction connection for the Late Devonian mass extinction, one of the largest in Earth history.Read moreRead less

The frontier research techniques to be employed will ensure that Australian geoscience remains at the forefront of international research. This project will also provide unprecedented research training opportunities for the next generation of Australian Earth Scientists. As prospective gold terranes are located in regional Australia, enhanced exploration and mining activity in future years may have significant economic and infrastructure benefits for rural and regional communities.Read moreRead less
The Effects of Crystal-Plastic Deformation on Zircon Geochemical Systems. This project establishes the significance of deformation-related fast-diffusion pathways on the zircon geochemical system and develops intragrain compositional variations as new tools for tracking geological processes. The unique application of zircon to constrain geological processes in numerous Earth Science disciplines over 4.4 billion years of Earth history ensures that results will have far-reaching impact in the Aust ....The Effects of Crystal-Plastic Deformation on Zircon Geochemical Systems. This project establishes the significance of deformation-related fast-diffusion pathways on the zircon geochemical system and develops intragrain compositional variations as new tools for tracking geological processes. The unique application of zircon to constrain geological processes in numerous Earth Science disciplines over 4.4 billion years of Earth history ensures that results will have far-reaching impact in the Australian and International Earth Science community. As such this project will maintain Australia's leading international reputation in accessory mineral research.Read moreRead less
Physical and Chemical Constraints of Fluid Activated Processes During the Polyphase Tectonic Evolution of the Olary Domain, S.A. The Olary Domain, eastern South Australia, underwent several phases of deformation and metamorphism. These events mobilised fluids leading, amongst other features, to the formation of breccia bodies and mineral deposits. The complex nature of the geological evolution of the region obscures relationships of fluid migration to the structural history. Fluid inclusion stud ....Physical and Chemical Constraints of Fluid Activated Processes During the Polyphase Tectonic Evolution of the Olary Domain, S.A. The Olary Domain, eastern South Australia, underwent several phases of deformation and metamorphism. These events mobilised fluids leading, amongst other features, to the formation of breccia bodies and mineral deposits. The complex nature of the geological evolution of the region obscures relationships of fluid migration to the structural history. Fluid inclusion studies and stable isotope analyses combined with structural analyses on micro to macro scales shall establish links between the thermal and structural evolution of the area. This will provide insigth into the scale and physico-chemical characteristics of fluids and mineralising processes an relate these to the tectono-thermal history.Read moreRead less
