This project will contribute to the fundamental science of understanding plate tectonic processes, and also have important practical implications for the oil and gas resources that are developed and hosted in continental margin settings. The study is therefore relevant to the National Research Priority goal of 'Developing Deep Earth Resources'. The project will also enhance our national scientific standing by addressing important scientific questions of global significance, and by establishing strong international collaborations with prominent researchers outside Australia. In addition, the work will help sustain a world-leading research capability and provide a training ground for a new generation of younger scientists in Australia.Read moreRead less
Application of the Wavelet Transform to Isostatic Analyses in Australia. Existing methods of determining the Earth's isostatic response assume ideal but unrealistic conditions. This project will develop a new technique for isostatic analysis, using the two-dimensional wavelet transform. This tool can resolve spectral components of geophysical data in the space domain, thus avoiding the problems arising during the conventional Fourier analysis. With innovative processing methods, maps of the crus ....Application of the Wavelet Transform to Isostatic Analyses in Australia. Existing methods of determining the Earth's isostatic response assume ideal but unrealistic conditions. This project will develop a new technique for isostatic analysis, using the two-dimensional wavelet transform. This tool can resolve spectral components of geophysical data in the space domain, thus avoiding the problems arising during the conventional Fourier analysis. With innovative processing methods, maps of the crustal thickness from gravity and topography data can be generated, a task usually reserved for costly seismic experiments. Analysis of the wavelet power spectrum would also benefit the exploration industry by identifying previously unknown sedimentary basins.Read moreRead less
Exploring deep Australia: 3-D imaging of the lithosphere beneath south-east Australia using multiple high density seismic arrays. The successful completion of this project will significantly improve our knowledge of the seismic structure of the Australian lithosphere, and hence improve our understanding of how the Australian continent came to be formed. In addition, the tomographic imaging methods that will be developed and applied to the individual and combined seismic arrays have a direct rele ....Exploring deep Australia: 3-D imaging of the lithosphere beneath south-east Australia using multiple high density seismic arrays. The successful completion of this project will significantly improve our knowledge of the seismic structure of the Australian lithosphere, and hence improve our understanding of how the Australian continent came to be formed. In addition, the tomographic imaging methods that will be developed and applied to the individual and combined seismic arrays have a direct relevance to the seismic imaging techniques used by the exploration industry. Finally, the creation of a combined dataset comprising records from ~300 stations will help keep Australia at the leading edge of observational seismology, as other countries (e.g. U.S.) begin to deploy very large seismic arrays.Read moreRead less
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. Thi ....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. 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
Large-scale three dimensional deformation of the lithosphere by subduction and mantle flow. We will be modelling of the dynamics of the Earth's crust and shallow lithosphere in response to the huge stresses created by plate motions. For Australia these stresses are transmitted from the distant plate boundaries, but they have a direct controlling influence on the evolution of the petroleum rich basins of Australia. These basins have reached maturity; further exploration will be in deep water wher ....Large-scale three dimensional deformation of the lithosphere by subduction and mantle flow. We will be modelling of the dynamics of the Earth's crust and shallow lithosphere in response to the huge stresses created by plate motions. For Australia these stresses are transmitted from the distant plate boundaries, but they have a direct controlling influence on the evolution of the petroleum rich basins of Australia. These basins have reached maturity; further exploration will be in deep water where geophysical prospecting methods are unreliable. Model-driven "exploration geodynamics" methods such as those we are developing will be needed to support traditional exploration techniques in these areas.Read moreRead less

Double and triple dating are exciting new ANU-Yale breakthroughs that can be used to more accurately identify the source of sediment in rivers and sedimentary rocks than is possible using existing techniques. They have fundamental applications in the study of erosion, tracing the source of heavy minerals in titanium deposits and in determining the source of sedimentary sequences that host oil. Under favourable circumstances double dating can be used also to date sediments that are devoid of fossils, which has direct application in oil exploration.Read moreRead less
Compressional Deformation and Uplift of Australia's Passive Southern Margin. The key project benefit will be to advance our understanding of the processes which cause active deformation of continental margins that are predicted by plate tectonic theory to be passive.

The key project benefit will be to advance our understanding of the processes which cause active deformation of continental margins that are predicted by plate tectonic theory to be passive. We will analyse Australia's 'passive' southern margin because it is an ideal natural laboratory in which to investigate the causes of the deformation of 'passive' continental margins. Hydrocarbon exploration interest and investment has waned along much of Australia's southern margin because of lack of understanding of the relative age of the formation of potentially hydrocarbon-bearing structures and the timing of hydrocarbon charge. This project will clarify their relative ages.Read moreRead less
