The early tectonic evolution of the Curnamona Province. This project aims to test the hypothesis that the Curnamona Province preserves evidence for an extension-related structural geology architecture. This will allow a comparison of the basin evolution, crustal architecture and mechanisms of basin development between the Curnamona Province and well-understood basins of the Mount Isa Inlier. The project is expected to add value to pre-existing databases, and deliver a plate tectonic and str ....The early tectonic evolution of the Curnamona Province. This project aims to test the hypothesis that the Curnamona Province preserves evidence for an extension-related structural geology architecture. This will allow a comparison of the basin evolution, crustal architecture and mechanisms of basin development between the Curnamona Province and well-understood basins of the Mount Isa Inlier. The project is expected to add value to pre-existing databases, and deliver a plate tectonic and structural framework to interpret basin evolution and constrain geochronology/geochemical analysis, and develop a three-dimesional crustal architecture. The results will provide new constraints on the evolution of the Australian plate, and how the Australian crust has evolved.Read moreRead less
Developing a new tectonothermal and mineralization history for the Capricorn Orogen, Western Australia: Assisting mineral exploration in greenfields terrains. Successful exploration models rely on the development of a reliable geological framework through which to understand the specific processes responsible for the formation of economic ore deposits. A framework cannot be constructed without robust age data. This Project will apply advanced geochronology, combined with regional- and deposit-sc ....Developing a new tectonothermal and mineralization history for the Capricorn Orogen, Western Australia: Assisting mineral exploration in greenfields terrains. Successful exploration models rely on the development of a reliable geological framework through which to understand the specific processes responsible for the formation of economic ore deposits. A framework cannot be constructed without robust age data. This Project will apply advanced geochronology, combined with regional- and deposit-scale field mapping, to formulate a new and improved stratigraphic and tectonic framework for a prospective greenfields region in Western Australia. Outcomes from this Project will lead to more effective exploration models and thereby better exploration targeting. Reducing uncertainty and risk in exploration is key to the discovery and development of deep Earth resources. Read moreRead less
Unearthing the Marginal Terranes of the South Australian Craton: Keystone of Proterozoic Australia. This project will investigate the buried geology of vast regions of northern South Australia that is likely to be compatible with rocks that host enormous mineral wealth including the giant Broken Hill and Olympic Dam deposits. We will access these buried rocks using a program of on-shore scientific drilling that will provide the ground truth for multi-million dollar federal and state government ....Unearthing the Marginal Terranes of the South Australian Craton: Keystone of Proterozoic Australia. This project will investigate the buried geology of vast regions of northern South Australia that is likely to be compatible with rocks that host enormous mineral wealth including the giant Broken Hill and Olympic Dam deposits. We will access these buried rocks using a program of on-shore scientific drilling that will provide the ground truth for multi-million dollar federal and state government funded geophysical data acquisition. Results will help identify prospective mineral belts and determine the processes responsible for their formation.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
Neoproterozoic global geodynamic and climatic events: were they linked? This project will study a unique cluster of global geodynamic and climatic events 850-700 million years ago that will help us to understand the interactions between the Earth's deep mantle, its crust, and its atmospheric climate. Academic values aside, the work will bring direct benefit to the Australian industry. Knowledge on the distribution of the Neoproterozoic plume events will provide new exploration targets for Ni-Cu- ....Neoproterozoic global geodynamic and climatic events: were they linked? This project will study a unique cluster of global geodynamic and climatic events 850-700 million years ago that will help us to understand the interactions between the Earth's deep mantle, its crust, and its atmospheric climate. Academic values aside, the work will bring direct benefit to the Australian industry. Knowledge on the distribution of the Neoproterozoic plume events will provide new exploration targets for Ni-Cu-PGE and V-Ti deposits. Better constrained palaeogeography will help to locate mineral-rich crustal provinces that were once connected. Understanding climatic consequences of global geodynamic events will help to better understand and respond to climate changes. Read moreRead less
Evolution of the Proterozoic lithosphere and its bearing of sediment hosted base metal mineralisation. This project aims to determine the aspects of lithospheric evolution that led to a concentration of giant base metal mineral deposits in the Early to Middle Proterozoic (ca 1.9-1.5 billion years ago). We propose to test three related hypotheses that, if validated, will fundamentally change our view of Proterozoic metallogenesis and the way the mineral industry approaches exploration for these ....Evolution of the Proterozoic lithosphere and its bearing of sediment hosted base metal mineralisation.

Numerical modelling of deformation partitioning and its role in metamorphism, tectonism and mineralization. Targeting blind mineralization is the biggest problem facing the Australian mining industry. The modelling developed in this project will integrate deformation, fluid and chemical processes and provide a means for understanding the deformation partitioning that localizes epigenetic ore regionally as well as along portions of large-scale structures. Applying this to known ore deposits may ....Numerical modelling of deformation partitioning and its role in metamorphism, tectonism and mineralization. Targeting blind mineralization is the biggest problem facing the Australian mining industry. The modelling developed in this project will integrate deformation, fluid and chemical processes and provide a means for understanding the deformation partitioning that localizes epigenetic ore regionally as well as along portions of large-scale structures. Applying this to known ore deposits may delineate adjacent plus regionally distributed zones where the deformation event responsible for mineralization is locally present at sufficient intensity to form ore. This would allow targeted deep drilling in ground with no ore close to the surface saving millions in drilling costs and dramatically increasing the financial viability of this industry.

Tetconic feedback and the long-term evolution of the continents. The continents are shaped through complex interactions between the primary tectonic processes of magmatism, metamorphism, deformation, erosion and sedimentation. Because these processes modify the distribution of heat producing elements, and are themselves temperature sensitive, they must be subject to important feedback loops. This project will use constraints on heat producing element distributions in the Australian crust, and th ....Tetconic feedback and the long-term evolution of the continents. The continents are shaped through complex interactions between the primary tectonic processes of magmatism, metamorphism, deformation, erosion and sedimentation. Because these processes modify the distribution of heat producing elements, and are themselves temperature sensitive, they must be subject to important feedback loops. This project will use constraints on heat producing element distributions in the Australian crust, and the way in which these distributions have evolved during various tectonic processes, to elucidate the nature and significance of "tectonic feedback" and its role in shaping the continents.Read moreRead less
Understanding the Sibao Orogenic Belt in South China: A Part of the Rodinian Supercontinent Assembly Adjacent to Australia. The Sibao Orogenic Belt (SOB) in South China is regarded as one of the worldwide 1300-1000 Ma mountain belts that record the assembly of the supercontinent Rodinia. However, recent work suggests that some of these mountain belts, including the SOB, were probably active until 900 Ma, thus questioning parts of the early Rodinia reconstructions. In this study we aim to deter ....Understanding the Sibao Orogenic Belt in South China: A Part of the Rodinian Supercontinent Assembly Adjacent to Australia. The Sibao Orogenic Belt (SOB) in South China is regarded as one of the worldwide 1300-1000 Ma mountain belts that record the assembly of the supercontinent Rodinia. However, recent work suggests that some of these mountain belts, including the SOB, were probably active until 900 Ma, thus questioning parts of the early Rodinia reconstructions. In this study we aim to determine the ages, and geochemical and structural characteristics of key tectonic units in the SOB. This will lead to a better understanding of the assembly process of Rodinia, and events occurring in continental blocks adjacent to Australia at that time.Read moreRead less
Computer simulation to study emergence of material texture in the Earth and Plate Tectonics. Plate tectonics has played a crucial role in the evolution and dynamics of the earth impacting on the diversity of life, mineralisation, and crustal dynamics. Despite its significance, how and under what conditions material texture and plate tectonics emerge from a proto-planet is not well understood.

Plate tectonics has played a crucial role in the evolution and dynamics of the earth impacting on the diversity of life, mineralisation, and crustal dynamics. Despite its significance, how and under what conditions material texture and plate tectonics emerge from a proto-planet is not well understood. New computational methodologies to simulate the evolution of the plate-mantle system will be used to study how the upper mantle emerges as a thermo-mechanically distinct boundary layer, how this emergent structure relates to anisotropy in the upper mantle, and how it is affected by cross-scale effects controlling fault zone behaviour and crustal dynamics.Read moreRead less
