Proterozoic tectonic evolution of Australia and India. Recent studies cast doubt on reconstructions of the Neoproterozoic supercontinent Rodinia, and on the tectonic coherence of East Gondwanaland (Australia, Antarctica and India). Within Australia, the relative positions of the major crustal blocks during most of the Proterozoic era remain largely unverified. Fossil magnetism in rocks of different ages from the major crustal blocks of Australia and India will be used to determine whether the ....Proterozoic tectonic evolution of Australia and India. Recent studies cast doubt on reconstructions of the Neoproterozoic supercontinent Rodinia, and on the tectonic coherence of East Gondwanaland (Australia, Antarctica and India). Within Australia, the relative positions of the major crustal blocks during most of the Proterozoic era remain largely unverified. Fossil magnetism in rocks of different ages from the major crustal blocks of Australia and India will be used to determine whether the blocks were together or were separated by large oceans during Proterozoic time. The results will place fundamental constraints on the geological, palaeogeographic, and palaeobiological evolution of Australia, Rodinia, and the early Earth as a whole.Read moreRead less
Reducing 3D geological uncertainty via improved data interpretation methods. The integrity of 3D geological models heavily relies on robust and consistent data interpretation.

The integrity of 3D geological models heavily relies on robust and consistent data interpretation. This project proposes an innovative workflow for 3D modelling to minimise geological uncertainty. Advanced visualisation and intelligent decision support methods will be combined to assist geological interpretation. Feedback on interpretation will be provided based on data evidence and consistency with expert knowledge and previous interpretations. The process can be considered as a spelling and grammar checker for geological interpretation. The outcome of this study aims to achieve an improved workflow that reduces model uncertainty, resulting in a broad and significant impact on the management of Australian mineral, energy and water resources.Read moreRead less

Optimising the use of geophysical data for modelling the Australian crust. This project aims to determine the optimal use of geophysical methods to model the Australian crust in four dimensions. These models provide an understanding of the tectonic history of a region and thus its mineral potential. Mineral resources are mostly being found undercover, requiring geophysical data to locate them. This project will combine recent developments in modelling geological uncertainty with data acquired fo ....Optimising the use of geophysical data for modelling the Australian crust. This project aims to determine the optimal use of geophysical methods to model the Australian crust in four dimensions. These models provide an understanding of the tectonic history of a region and thus its mineral potential. Mineral resources are mostly being found undercover, requiring geophysical data to locate them. This project will combine recent developments in modelling geological uncertainty with data acquired for locating zones of mineralisation. The outcomes will help guide Australian government policy to draw on publicly-available datasets that provide a basis for mineral exploration performed by companies, and supported by research institutions.Read moreRead less

Outcomes will include significant new information about the structure and formation of the Earth's crust and the underlying mantle. An improved framework for interpreting the architecture of Australia and other continents will be directly relevant to exploration for world-class economic deposits, the Earth resources on which society depends. Innovations in geochemical technology and in the integration of information from geochemistry, geophysics and geodynamics will maintain our high international profile in research relevant to National Priority 1.6 (Developing Deep Earth Resources). The project and its interaction with the minerals industry will provide advanced Postgraduate training in a field critical to Australia's future.Read moreRead less
Advanced Electromagnetic Sensors and Magnetic Gradiometers for Natural Resources Exploration and Future Space Missions. Australia will benefit from the long-standing world-class mining exploration industry.

Australia will benefit from the long-standing world-class mining exploration industry. The new magnetic gradiometer system would greatly enhance their arsenal of geophysical exploration tools, especially for the detection of both magnetically and/or conductive minerals like nickel sulphide. Due to the inherent skin depth issues of conductive cover, a unique condition in Australia, a low frequency electromagnetic survey system is one of the best methods to penetrate the cover and investigate deeper geological structures. The low frequency isolation system developed in this project will improve the survey instrument performance down to 4Hz, providing capability to explore resources about 50-100% deeper than existing instrumentation allows.Read moreRead less

Our detailed chronostratigraphic framework for Canning Basin and the biomarker data on source rock history provides an increased understanding of the resource potential of the basin and similar settings worldwide. Furthermore this high-fidelity data will be used by companies to develop the 'next' generation of hydrocarbon industry modelling workflows. Our research program also has important environmental implications; providing insight into drivers for Devonian mass extinctions and as periods of past biotic crises become increasingly understood they can provide critical insights into determining the thresholds of environmental change, which may potentially serve as analogues for present-day global climate change scenarios.Read moreRead less
Environmental geodesy: variations of sea level and water storage in the Australian region. It is essential for Australia's long-term planning and security that the effects of global warming on our nation's water resources and coastlines are quantified. Sea level variations projected into the future vary around Australia and have large uncertainties, yet the impacts have substantial social and financial ramifications for our community.

It is essential for Australia's long-term planning and security that the effects of global warming on our nation's water resources and coastlines are quantified. Sea level variations projected into the future vary around Australia and have large uncertainties, yet the impacts have substantial social and financial ramifications for our community. Australia hasn't yet quantified accurately its critical water resources nor how they are changing. This proposal will address both these issues, providing for the first time valuable and accurate information for planning appropriate strategies to mitigate the impact of sea level rise and water storage on the Australian society.Read moreRead less
