Multiscale dynamics of ore body formation. Future discoveries of giant ore-bodies will undoubtedly be under surface cover. Modelling of new data from South Australia and Western Australia will define targeting criteria for new major ore-bodies, thus exploiting Australia's deep earth resource potential. New understanding of controls on mineralisation decrease exploration risk. Ore-bodies, such as Olympic Dam, have made major contributions to Australia's economy over past decades and promise to ad ....Multiscale dynamics of ore body formation. Future discoveries of giant ore-bodies will undoubtedly be under surface cover. Modelling of new data from South Australia and Western Australia will define targeting criteria for new major ore-bodies, thus exploiting Australia's deep earth resource potential. New understanding of controls on mineralisation decrease exploration risk. Ore-bodies, such as Olympic Dam, have made major contributions to Australia's economy over past decades and promise to add increased value over future decades. This project enhances the probability that at least one other ore-body of this type will be discovered. Such discoveries contribute directly to the wealth of Australia through export earnings and accelerate the development of regional infrastructure and new technological development.Read moreRead less
Enhanced 3-D seismic structure for Southwest Australia. The ancient cratonic lithosphere of Southwest Australia appears to have a distinct contrast in geophysical properties and complex geologic structure, while having some of the highest levels of earthquakes on the continent. The project aims to produce novel 3-D models of this region that combine new seismic data collected over two years with previously collected geophysical datasets from the partner investigators. A compilation of 3-D models ....Enhanced 3-D seismic structure for Southwest Australia. The ancient cratonic lithosphere of Southwest Australia appears to have a distinct contrast in geophysical properties and complex geologic structure, while having some of the highest levels of earthquakes on the continent. The project aims to produce novel 3-D models of this region that combine new seismic data collected over two years with previously collected geophysical datasets from the partner investigators. A compilation of 3-D models will subsequently be developed, to form an effective characterisation of the geologic structure of the craton and its margins. These models will provide enhanced assessment of seismic ground shaking from regional earthquakes and facilitate an improved understanding of mineral resource potential. Read moreRead less
Craton modification and growth: the east Albany-Fraser Orogen in three-dimensions. The objective of this work is to achieve new, synergistic techniques for delineating the three-dimensional structure of the east Albany-Fraser Orogen in Western Australia, and the lithospheric structure below it. These methods will guide understanding of the potential for mineral resources in this region with little surface geological exposure.
Deep time extinctions and environments in Australian underwater caves. This project aims to investigate the unique submerged Mt Gambier fossil deposits to determine the role environmental change had on large Australian mammal extinctions. By using a combination of technical diving and scientific expertise to study untouched fossil deposits from underwater caves, this project expects to provide greater understanding of past ecosystems and animals, advancements in geochronological techniques, and ....Deep time extinctions and environments in Australian underwater caves. This project aims to investigate the unique submerged Mt Gambier fossil deposits to determine the role environmental change had on large Australian mammal extinctions. By using a combination of technical diving and scientific expertise to study untouched fossil deposits from underwater caves, this project expects to provide greater understanding of past ecosystems and animals, advancements in geochronological techniques, and data critical to prepare Australians for action in protecting our biological heritage. Expected outcomes include insights into cave conservation and protection of underwater cave systems, updated policies on cave management, and promotion of our understanding of Australian geo-heritage through education and displays.Read moreRead less
Correction of non-linearity in inductively-coupled-plasma mass-spectrometry. Chemical analyses by mass spectrometers underpin key Australian economic sectors, particularly minerals and agriculture. The quadrupole inductively-coupled-plasma mass-spectrometer has seen a particular rise in prominence over last 25 years. In this collaboration between mass spectrometrists and the leading instrument designer, we will improve the linearity of its detection system for more precise and accurate data.

Chemical analyses by mass spectrometers underpin key Australian economic sectors, particularly minerals and agriculture. The quadrupole inductively-coupled-plasma mass-spectrometer has seen a particular rise in prominence over last 25 years. In this collaboration between mass spectrometrists and the leading instrument designer, we will improve the linearity of its detection system for more precise and accurate data. Better elemental and isotope ratio data from these high-throughput instruments will open up new real-world applications in many areas of Australian interest, such as biosecurity, forensics, groundwater management, and drug design. The research will also inform design of the next generation instruments by the industry partner.Read moreRead less
Dynamic earth models for frontier diamond exploration. This project aims to investigate the link between continent motion and mantle upwelling over the last billion years by combining tectonic reconstructions and recently developed dynamic earth models with the global and Australian rock record. Mantle upwelling is thought to cause eruptions of large volcanic provinces and kimberlites, the primary source rock for diamonds. The project expects to develop a technique to map kimberlite potential in ....Dynamic earth models for frontier diamond exploration. This project aims to investigate the link between continent motion and mantle upwelling over the last billion years by combining tectonic reconstructions and recently developed dynamic earth models with the global and Australian rock record. Mantle upwelling is thought to cause eruptions of large volcanic provinces and kimberlites, the primary source rock for diamonds. The project expects to develop a technique to map kimberlite potential in under-explored regions such as Australia. Significant benefits from the project will be the reduction of economic risks in diamond exploration, the training of a researcher in exploration geodynamics, and understanding the link between supercontinents and mantle upwelling.Read moreRead less

Geodetic and hydrogeological investigations of groundwater abstraction from confined aquifers: elastic response, heights, and sea level change. Parts of Perth are subsiding by as much as 5 millimetres (mm) per year, thus accelerating sea level rise relative to the land from 3 mm per year to 8 mm per year. The subsidence is most likely due to increased groundwater abstraction. This project aims to extend subsidence mapping in time and space using satellite-borne synthetic aperture radar, calibrat ....Geodetic and hydrogeological investigations of groundwater abstraction from confined aquifers: elastic response, heights, and sea level change. Parts of Perth are subsiding by as much as 5 millimetres (mm) per year, thus accelerating sea level rise relative to the land from 3 mm per year to 8 mm per year. The subsidence is most likely due to increased groundwater abstraction. This project aims to extend subsidence mapping in time and space using satellite-borne synthetic aperture radar, calibrated by complementary geodetic techniques, and coupled with new hydrogeological inputs from the Western Australian Department of Water. The research aims to provide science-based information to planners and managers on coastal vulnerability and determine the land response to groundwater abstraction. This will also allow for the correction of sea level change measurements from tide gauges.Read moreRead less
