AusLAMP provides unparalleled geophysical information aimed at unravelling the tectonic history of the Australian continent and its mineral potential. The project will use thermodynamically based geodynamic simulators to jointly analyse and quantify intraplate deformation. This will illuminate the cause of driving fluid flow thorough the lithosphere, mineralisation phenomena, their datasets and geometries, and dynamic aspects of the processes driving mineral systems.Read moreRead less

Advanced gravity and electromagnetic methods for uncovering the deep Earth. This project aims to improve the sensitivity of airborne gravity gradiometers and electromagnetic sensors so airborne surveys can detect underground structures at greater depths. Aircraft motion and turbulence limit the effectiveness of existing instruments. Advanced vibration isolation and noise reduction algorithms will allow instruments to image to significantly greater depths, to map geology more accurately. This is expected to contribute to the discovery of new economic mineral and hydrocarbon resources.Read moreRead less
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
A multidisciplinary study of the Karoo Basin: chronology of a mass extinction, configuration of a supercontinent. Development plans for Australia's North-West (NW) shelf will expand the existing supply of natural gas and help manage greenhouse gas emissions through an innovative carbon sequestration project.

Development plans for Australia's North-West (NW) shelf will expand the existing supply of natural gas and help manage greenhouse gas emissions through an innovative carbon sequestration project. A better understanding of well-exposed geology of the Karoo Basin will help evaluate the submarine deposits of Australia's NW shelf, essential for both improving yield from the new Gorgon gas fields and understanding subterranean reservoir capabilities for carbon dioxide injection This study will also improve our scientific understanding of the timing and mechanisms of the end-Paleozoic mass extinction, the most significant event in the history of life on Earth.Read moreRead less

Summary
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

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. 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.

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
Theoretical and experimental study of elastic properties of porous media permeated by aligned fractures. The aim of the project is to develop a theoretical model for the elastic properties of fractured porous reservoir rocks, taking into account the wave-induced fluid flow between pores and fractures. This will be done by theoretical analysis based on the model of fractures as planes of discontinuity in porous rock, and on the theory of wave propagation in anisotropic porous media. The theoretic ....Theoretical and experimental study of elastic properties of porous media permeated by aligned fractures. The aim of the project is to develop a theoretical model for the elastic properties of fractured porous reservoir rocks, taking into account the wave-induced fluid flow between pores and fractures. This will be done by theoretical analysis based on the model of fractures as planes of discontinuity in porous rock, and on the theory of wave propagation in anisotropic porous media. The theoretical model will be verified using numerical simulations and ultrasonic measurements made on synthetic porous and fractured samples. The results are expected to benefit seismic exploration and the production of oil and gas in fractured reservoirs.Read moreRead less
