Summary
Instrumentation for combined seismic and electromagnetic Earth sounding. The set of geophysical recorders will provide the means to enhance understanding of the structure of the Australian continent in 3-D. The interpretation of multiple images of Earth structure will help to link features in the crust and mantle beneath, and provide controls on the evolution and assembly of the present continent, with a major contribution to possible geotransects as recommended in the 2003 National Strategic Pl ....Instrumentation for combined seismic and electromagnetic Earth sounding. The set of geophysical recorders will provide the means to enhance understanding of the structure of the Australian continent in 3-D. The interpretation of multiple images of Earth structure will help to link features in the crust and mantle beneath, and provide controls on the evolution and assembly of the present continent, with a major contribution to possible geotransects as recommended in the 2003 National Strategic Plan for the Geosciences. Combining seismic and electromagnetic methods will provide both geochemeical and geophysical constaints, e.g., on zones of alteration and shear with the potential for deep mineralisation.

How responsive are continental interiors to the geodynamic evolution of plate margins? An Australian case study. The outcomes of this project will advance our understanding of the evolution and dynamics of the Australian plate by improving knowledge of the way plate driving forces shaped the continental interior. This will lead to a refinement of existing geological models describing the history of the Australian continent, and will provide a valuable backdrop for the current focus on the cont ....How responsive are continental interiors to the geodynamic evolution of plate margins? An Australian case study. The outcomes of this project will advance our understanding of the evolution and dynamics of the Australian plate by improving knowledge of the way plate driving forces shaped the continental interior. This will lead to a refinement of existing geological models describing the history of the Australian continent, and will provide a valuable backdrop for the current focus on the contemporary state of the Australian plate. The study will also provide a framework for petroleum exploration models in the central Australian basins, since they rely crucially on the thermal and structural datasets that will be produced in this project.Read moreRead less
Thermal regimes, flexure and duration: establishing the framework for intracratonic orogeny in central Australia. Intracratonic orogeny is a confronting phenomena because it contradicts the plate tectonic paradigm, which highlights the apparently rigidity of the lithospheric plates. Central Australia contains an exceptional record of intracratonic orogeny, expressed by the formation of the Petermann and Alice Springs orogens. This project will quantify the duration, and thermal conditions assoc ....Thermal regimes, flexure and duration: establishing the framework for intracratonic orogeny in central Australia. Intracratonic orogeny is a confronting phenomena because it contradicts the plate tectonic paradigm, which highlights the apparently rigidity of the lithospheric plates. Central Australia contains an exceptional record of intracratonic orogeny, expressed by the formation of the Petermann and Alice Springs orogens. This project will quantify the duration, and thermal conditions associated with the comparatively poorly known Petermann Orogen. Given the importance of intracratonic deformation in shaping the lithospheric architecture of central Australia, understanding the history of the Petermann Orogeny is essential to developing models that describe the evolution of the Australian continent, and continental interiors in general.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. 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 ....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. 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
Deciphering the tectonic history of the Musgrave Block to assist mineral explorers and regional synthesis programs. Effective mineral exploration strategies in complex basement terrains are increasingly reliant on integrated, data-rich, tectonic models. In this project we will focus a large multidisciplinary team to develop a tectonic model for the evolution of the Musgrave Block in central Australia. This large, poorly understood terrain occupies a critical structural location, separating the ....Deciphering the tectonic history of the Musgrave Block to assist mineral explorers and regional synthesis programs. Effective mineral exploration strategies in complex basement terrains are increasingly reliant on integrated, data-rich, tectonic models. In this project we will focus a large multidisciplinary team to develop a tectonic model for the evolution of the Musgrave Block in central Australia. This large, poorly understood terrain occupies a critical structural location, separating the northern and southern Australian cratons. By constraining models of crustal evolution and architecture, the project will underpin future mineral exploration programs in this highly prospective greenfields region and define the role of the Musgrave Block in the assembly of Proterozoic Australia.Read moreRead less
Developing a Tectonic Framework for the Gawler Craton: Paving the Way for Successful Mineral Exploration Programs. The late Archaean to Mesoproterozoic Gawler Craton is the major Precambrian province in southern Australia. However, despite containing one of the largest orebodies on Earth, exploration expenditure in the craton has been comparatively low, and hampered by insufficient knowledge of the craton's tectonic systems. This project uses an integrated package of geochemical, isotopic and ....Developing a Tectonic Framework for the Gawler Craton: Paving the Way for Successful Mineral Exploration Programs. The late Archaean to Mesoproterozoic Gawler Craton is the major Precambrian province in southern Australia. However, despite containing one of the largest orebodies on Earth, exploration expenditure in the craton has been comparatively low, and hampered by insufficient knowledge of the craton's tectonic systems. This project uses an integrated package of geochemical, isotopic and geophysical tools to develop a comprehensive model for the tectonic evolution of the Gawler Craton. The project will constrain the development of the Gawler Craton in the context of Precambrian Australian evolution, and offer insights into universal processes of lithosphere formation, growth and stabilisation.Read moreRead less
Magmatism, Metamorphism and Mineralisation: The Development of an Isotopic and Geochemical Framework for the Curnamona Cu-Au Province. Recent advances have highlighted the potential significance of the Olary Domain in the Curnamona Province in southern Australia as an important Proterozoic copper-gold district. However, an outstanding problem yet to be solved is the interplay between mineralisation, granitic magmatism and the metamorphic history of the Province. This multi-disciplinary project ....Magmatism, Metamorphism and Mineralisation: The Development of an Isotopic and Geochemical Framework for the Curnamona Cu-Au Province. Recent advances have highlighted the potential significance of the Olary Domain in the Curnamona Province in southern Australia as an important Proterozoic copper-gold district. However, an outstanding problem yet to be solved is the interplay between mineralisation, granitic magmatism and the metamorphic history of the Province. This multi-disciplinary project will use isotopic and geochemical tools to develop an integrated geologic framework within which to view mineralisation. The outcomes will enhance the prospectivity of the region and make an important contribution to the globally relevant question of controls on Proterozoic copper-gold systems.Read moreRead less
Present-Day Stress and Tectonics of Deltas and Deepwater Fold-Thrust Belts. The key benefit of the project will be to advance our understanding of the geological processes that control the development of deltas, and of the fold-thrust belts located in deepwater adjacent to deltas, by analysis of five examples worldwide. Global hydrocarbon exploration is successfully moving to deepwater fold-thrust belts.

The key benefit of the project will be to advance our understanding of the geological processes that control the development of deltas, and of the fold-thrust belts located in deepwater adjacent to deltas, by analysis of five examples worldwide. Global hydrocarbon exploration is successfully moving to deepwater fold-thrust belts. One of Australia's key under-explored frontier petroleum provinces is the Australian Bight Basin. The prospective parts of this basin comprise delta/deepwater fold-thrust belt systems and analysis of more data-rich systems worldwide will help provide the geological knowledge required to help re-invigorate exploration in the Bight Basin.Read moreRead less

Finally, the project will increase the institutional capacity for contract research in SE Asia.Read moreRead less
Three-dimensional magnetotelluric imaging of lithospheric-scale mineral systems from source to deposit. Geochemical studies indicate that world-class mineral deposits are partly sourced from fluids emerging from Earth's mantle and lower crust. Finding major mineral deposits in the future will therefore require knowledge of which parts of the crust and mantle yield the most prospective locations. However, there are few methods that can image deep Earth resources, and these can be very expensive ....Three-dimensional magnetotelluric imaging of lithospheric-scale mineral systems from source to deposit. Geochemical studies indicate that world-class mineral deposits are partly sourced from fluids emerging from Earth's mantle and lower crust. Finding major mineral deposits in the future will therefore require knowledge of which parts of the crust and mantle yield the most prospective locations. However, there are few methods that can image deep Earth resources, and these can be very expensive. We propose to develop the magnetotelluric method as a low-cost and rapid approach for delineating 3D information on deep mineral systems beneath existing major deposits, and adapting this to explore in greenfield locations.Read moreRead less
