LATE PALAEOZOIC PALAEOGEOGRAPHY OF CENTRAL ASIA: A PALAEOBIOGEOGRAPHICAL APPROACH USING IMPROVED BIOSTRATIGRAPHY. Fossil data from Central Asia (Afghanistan, Uzbekistan, Pakistan, NW China, Mongolia, Altaids) indicate significant degree of palaeo-latitudinal variation in biogeographical patterns across the Palaeo-Tethys and its flanking shelves during Late Palaeozoic, but details of these patterns and implications for enhancing contemporaneous palaeogeographical models are virtually unknown.

Fossil data from Central Asia (Afghanistan, Uzbekistan, Pakistan, NW China, Mongolia, Altaids) indicate significant degree of palaeo-latitudinal variation in biogeographical patterns across the Palaeo-Tethys and its flanking shelves during Late Palaeozoic, but details of these patterns and implications for enhancing contemporaneous palaeogeographical models are virtually unknown. This project will analyse the biogeographical patterns of Late Palaeozoic brachiopod, coral, fusulinid faunas using advanced statistical methods, and integrate biogeographical signals with palaeomagnetic data to constrain models for the Late Palaeozoic geological evolution of Central Asia-a vast region that is known to bear enormous potential for natural resources but remains geologically little explored.Read moreRead less
Crustal Stress Field of SE Asia. The key project benefit is to advance our fundamental understanding of tectonic processes such as sedimentary basin development and continental collision. It has major implications for natural hazard assessment and resources exploration in SE Asia, consistent with Australia's participation in the APEC Energy Working Group.

It has major implications for natural hazard assessment and resources exploration in SE Asia, consistent with Australia's participation in the APEC Energy Working Group. The project has major ancillary benefits. It will strengthen international links between Australia, SE Asia, the UK, USA and Germany. It will provide high-quality research and training experience for the APD and PhD student involved, whom will spend time with research groups and oil companies in Australia, UK, USA and SE Asia. Finally, the project will increase the institutional capacity for contract research in SE Asia.Read moreRead less

Accurate timekeeping is central to the environmental and archaeological sciences.

Accurate timekeeping is central to the environmental and archaeological sciences. Radiocarbon dating is the leading geochronological technique for events of the past 50,000 years, but the issue for sample contamination remains a major source of concern. Avoidance of contaminants can be achieved through the identification of specific biomolecular compounds that unambiguously formed part of the original sample, and the isolation of these biomolecules for radiocarbon dating using accelerator mass spectrometry. Here we request funds to establish Australia's first compound-specific radiocarbon dating facility, to obtain ages of high accuracy for key studies of climate and landscape change, evolutionary biology and archaeology.Read moreRead less
Longshore Sediment Supply to the Deep Ocean. The current model to supply sand to deep water off continental margins is that provided by rivers operating at low sea level. We propose an alternative model in which sand is provided by longshore transport to deep water at high sea level north of Fraser Island, SE Queensland. Here we will test the validity of our new model by site studies of sea bottom morphology, composition and dynamics. If the model proves true, we will have: 1) generated an entir ....Longshore Sediment Supply to the Deep Ocean.

We propose an alternative model in which sand is provided by longshore transport to deep water at high sea level north of Fraser Island, SE Queensland. Here we will test the validity of our new model by site studies of sea bottom morphology, composition and dynamics. If the model proves true, we will have: 1) generated an entirely new exploration model for deepwater hydrocarbons, 2) provided new expertise and seabed maps for generating a superior marine naval defence capability.Read moreRead less

Dating the aboriginal rock art sequence of the Kimberley in north west Australia. This project aims to develop a robust time scale for the known aboriginal rock art sequence in the Kimberley, Western Australia (WA). The project will use new knowledge of complex processes on sandstone surfaces across the north Kimberley, and an innovative combination of four scientific dating methods developed through our earlier work.

This project aims to develop a robust time scale for the known aboriginal rock art sequence in the Kimberley, Western Australia (WA). The project will use new knowledge of complex processes on sandstone surfaces across the north Kimberley, and an innovative combination of four scientific dating methods developed through our earlier work. The project expects to provide a well-dated sequence for Kimberley rock art based on replication of results, confirmation across different methods, and a large interdisciplinary data set. The project will allow rigorous analysis of the relationship between dating results and rock art styles that has not previously been possible, and give new insights into Australia’s deep indigenous heritage. This will have a significant impact for future efforts in rock art conservation, and lay a foundation for cultural tourism, with important benefits for the local economy and health of regional indigenous communities.Read moreRead less

This project aims to investigate the co-evolution of life and environments during Earth’s first two billion years using iron-rich chemical sediments deposited from global oceans. The project expects to generate knowledge of Earth’s transition into a planet habitable for complex life by combining nanoscale characterisation techniques, with laboratory experiments and theoretical modelling. Expected outcomes include transformative ideas about the role of life in iron and phosphorus cycles, the chemistry of the early ocean, ancient biological productivity, the antiquity of oxygenic photosynthesis and the rise of oxygen. The project will also deliver new conceptual models for the formation of the host-rocks for most of the world’s iron resources, improving how we explore for iron in the Earth’s crust. This should provide benefits to understanding geobiology on Earth and other planets.Read moreRead less

The project outcomes will provide better models for predicting super-eruptions, thereby informing global climate change research, urban planning, and transport and telecommunications infrastructure engineering. Results will also improve existing volcanic risk models used by insurers to quantify volcanic risks and calculate expected losses from volcanic eruptions, and greatly improve our ability to use eruption deposits as time markers for important events in human evolution.Read moreRead less

Summary
A world-class rock magnetic facility to support Australian palaeomagnetic and environmental research. Magnetic properties of rocks and environmental particles provide information about a vast range of geological and environmental processes. We propose to develop a facility that will enable detection and interpretation of these magnetic signals to aid understanding of climate change, mineral exploration, and the geological development of Australia.
