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.

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
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
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

Summary
A new X-ray spectrometer facility for VIEPS: major and trace element characterisation of geological materials. Australia has a well-earned reputation as a leading innovator in analytical geochemistry and the acquisition of this instrumentation will reinforce that standing. The equipment will support a broad range of research activities and enhance our capability for research training at Honours and post-graduate student level. In addition this project addresses directly our current National Rese ....A new X-ray spectrometer facility for VIEPS: major and trace element characterisation of geological materials. Australia has a well-earned reputation as a leading innovator in analytical geochemistry and the acquisition of this instrumentation will reinforce that standing. The equipment will support a broad range of research activities and enhance our capability for research training at Honours and post-graduate student level. In addition this project addresses directly our current National Research Priority 'an environmentally sustainable Australia', and priority goals 'Developing deep earth resources' and 'Responding to climate change and variability'Read moreRead less
