Four dimensional lithospheric evolution and controls on mineral system distribution in Neoarchean to Paleoproterozoic terranes. This project will resolve important questions about the links between the evolution and preservation of continents and important mineral deposits in Australia and West Africa between 2.7 and 1.8 billion years ago. The results will improve the understanding of a key period of Earth history and make a major contribution to mineral exploration.
Resolving the influence of intraplate orogenesis on continental margin tectonics. Novel, multi-dating of continental sedimentary rocks will be undertaken to examine the effects of a high sediment flux from an enigmatic, major mountain-building event on a distant continental margin. This will expand our understanding of the range of tectonic influences between continental interiors and margins and onshore resource potential.
Finding Porphyry Copper with zircon trace elements & hyperspectral display. Copper mine discovery rates lag behind world needs. One way to find copper in the World’s Ring of Fire is to measure compositions of zircons which are durable minerals concentrated in stream sands and spreadout long distances below a deposit. 100s of zircon from a cup of sand constitute a sample. Zircon chemical features that indicate possible mines are mostly understood, but nature is complicated. Beyond the 26 channel ....Finding Porphyry Copper with zircon trace elements & hyperspectral display. Copper mine discovery rates lag behind world needs. One way to find copper in the World’s Ring of Fire is to measure compositions of zircons which are durable minerals concentrated in stream sands and spreadout long distances below a deposit. 100s of zircon from a cup of sand constitute a sample. Zircon chemical features that indicate possible mines are mostly understood, but nature is complicated. Beyond the 26 channels of chemical data for each grain in the 10,000s of analyses, there are 7 layers of lab imaging data that are not carried along in a convenient way. Geologists need smart computer systems to find useful relationships among the 33 channels and to discover relations within and between samples to find more mineable copper. Read moreRead less

Summary
Stability of accessory minerals during low temperature geological processes. The project aims to improve Australia’s ability to discover mineral deposits beneath sedimentary basins by determining whether detrital accessory minerals in sedimentary basins can be an effective exploration tool. This project expects to generate new knowledge on the stability of detrital accessory minerals in the sedimentary cycle using observations from natural rocks and laboratory experiments. Expected outcomes incl ....Stability of accessory minerals during low temperature geological processes. The project aims to improve Australia’s ability to discover mineral deposits beneath sedimentary basins by determining whether detrital accessory minerals in sedimentary basins can be an effective exploration tool. This project expects to generate new knowledge on the stability of detrital accessory minerals in the sedimentary cycle using observations from natural rocks and laboratory experiments. Expected outcomes include an assessment of the accessory minerals that are best suited to exploration vectoring studies in sedimentary basins. This should provide significant benefits to government and industry by improving mineral exploration methods and also has implications for geochronology and provenance studies.Read moreRead less

Events through time: eruptions, extinctions, impacts, ore-bodies and orogenies - upgrading the national argon geochronology network. Nine universities and the CSIRO will replace aged and obsolete equipment with new mass spectrometers which will be strategically placed at opposite ends of our continent to improve access for Australian researchers to these instruments for which there is high demand. These instruments will allow more exact dating of events such as eruptions, impacts, climate change ....Events through time: eruptions, extinctions, impacts, ore-bodies and orogenies - upgrading the national argon geochronology network.

Where to find giant porphyry and epithermal gold and copper deposits. This project will determine when and where giant gold or copper deposits should form, consolidating links with Indonesia, and using South East Asia as a vast natural laboratory in which to examine the effect of large-scale tectonic processes. The project will produce a four-dimensional virtual exploration toolkit to show how to apply the methods.
Chronostratigraphic and tectonothermal history of the northern Capricorn Orogen: constructing a geological framework for understanding mineral systems. The application of innovative age dating techniques with field mapping and a new deep seismic survey across the Capricorn Orogen by this project will help construct a vastly improved geological framework for understanding large mineral systems.

Linking Australia’s basement and cover mineral systems . The aim of this research is to use revolutionary new mineral-dating techniques to test the hypothesis that low-temperature fluids can transport metals from Australia's richly endowed geological basement to form new mineral deposits in the sedimentary basins that cover most of the continent. Sedimentary-hosted mineral systems are the largest source of the critical metal cobalt and the second largest source of copper on Earth. These two meta ....Linking Australia’s basement and cover mineral systems . The aim of this research is to use revolutionary new mineral-dating techniques to test the hypothesis that low-temperature fluids can transport metals from Australia's richly endowed geological basement to form new mineral deposits in the sedimentary basins that cover most of the continent. Sedimentary-hosted mineral systems are the largest source of the critical metal cobalt and the second largest source of copper on Earth. These two metals are essential to developing the green energy infrastructure and technologies that underpin a net zero economy. The expected outcomes are a detailed record of paleo-fluid flow and metal cycling in Australia's highly prospective sedimentary basins. Read moreRead less

Understanding the Thomson Orogen, a geological region which straddles the New South Wales and Queensland border, is critical for developing geodynamic models for the evolution of eastern Australia, and assessing resource potential. However, it lies under the Great Artesian Basin. This project focusses on ground truthing geophysical acquisition studies using drill core from a targeted drilling program, designed to maximise the available tectono-stratigraphic information. The outcome intends to be a 3D geological map of the region, which can be interrogated for mineral exploration targeting, and from which 4D evolutionary geodynamic models of eastern Australian can be integrated.Read moreRead less
Multiple vertical tectonic movements in a continental interior: consequences of flat-subduction and foundering of an oceanic plateau? This project will investigate how the subduction of particularly thick oceanic crust impacts on the landscape, climate, structure and composition of the adjacent continent. It will help in understanding the history and distribution of mineral and hydrocarbon resources, of similar provinces in Australia.
