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.
Geochemistry of ore metals at very high temperatures. The world’s largest copper and gold mines occur in extinct volcanoes around the Pacific Rim. Understanding how these essential metals are mobilised from magmas in the roots of volcanoes to become ore deposits and how to recognize where this has occurred is crucial in exploration for new deposits.
The Missing link in the Tasmanides: evaluating tectonic evolution and resource exploration potential of the southern Thomson Fold belt. 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 dril ....The Missing link in the Tasmanides: evaluating tectonic evolution and resource exploration potential of the southern Thomson Fold belt. 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
Tectonic geography of the world's oldest petroleum play, the McArthur Basin. This projects aims to develop a 4D tectonic geography framework to support the effective exploration of the McArthur Basin. This project will construct this by a) investigating the evolving tectonic setting, b) examining intra-basin correlations and trace the source to sink sediment provenance, c) unraveling the depositional geography using novel isotopic proxies, and, d) constructing the subsequent thermal history of ....Tectonic geography of the world's oldest petroleum play, the McArthur Basin.

This project will construct this by a) investigating the evolving tectonic setting, b) examining intra-basin correlations and trace the source to sink sediment provenance, c) unraveling the depositional geography using novel isotopic proxies, and, d) constructing the subsequent thermal history of the basin. The techniques developed through this project will de-risk the exploration for petroleum in this basin, and be applicable in opening up Proterozoic petroleum elsewhere in Australia and internationally.Read moreRead less
Bromine isotopic evolution of the Earth and solar system. A world first capability of innovative isotopic tracing within the earth and solar system materials will be developed. Insights into how planets are formed and the transport of materials and heat within them will be tracked through the application of the naturally occurring isotopes of Bromine.
ARC Centre of Excellence for Core to Crust Fluid Systems. Water is essential for human existence, indeed for life's beginning. The circulation of water between the surface and the deep interior lubricates the internal dynamics that keep Earth geologically alive; it is crucial to most Earth systems, including the evolution of the hydrospher/atmosphere/biosphere, and the development of giant ore deposits. However, the origin, abundance, speciation and movements of fluids inside Earth are largely u ....ARC Centre of Excellence for Core to Crust Fluid Systems. Water is essential for human existence, indeed for life's beginning. The circulation of water between the surface and the deep interior lubricates the internal dynamics that keep Earth geologically alive; it is crucial to most Earth systems, including the evolution of the hydrospher/atmosphere/biosphere, and the development of giant ore deposits. However, the origin, abundance, speciation and movements of fluids inside Earth are largely unknown, and represent key issues in modern geoscience. This CoE will integrate previously disparate fields - geology, tectonics, geochemistry, petrophysics, geophysics and dynamic modelling - to understand the workings of Earth's deep plumbing system.Read moreRead less
Just add water: a recipe for the deformation of continental interiors. By integrating geochemical, geochronological and microstructural datasets, this project aims to provide a novel framework for fluid–rock systems in the lithosphere. Plate tectonics argues that continental interiors are usually stable, rigid and undeformable, yet mountain belts have formed in these locations. Their existence suggests that strong crust can be weakened to allow the accommodation of deforming forces, but the unde ....Just add water: a recipe for the deformation of continental interiors. By integrating geochemical, geochronological and microstructural datasets, this project aims to provide a novel framework for fluid–rock systems in the lithosphere. Plate tectonics argues that continental interiors are usually stable, rigid and undeformable, yet mountain belts have formed in these locations. Their existence suggests that strong crust can be weakened to allow the accommodation of deforming forces, but the underlying causes for this change in behaviour are not clear. This project aims to investigate the largely unexplored impact of fluid flow on the characteristics of intraplate deformation. This would improve our understanding of what modulates the strength of continental crust, including its susceptibility to seismic activity, and the ways in which fluids interact with the deep crust, including their mineralisation potential.Read moreRead less
Testing continental growth models with calcium and strontium isotopes. The Project aims to chart the evolution of the Earth’s primordial mantle and oceans between 3.75 and 2.8 billion years ago using calcium and strontium isotopes in ancient igneous and sedimentary rocks. A novel solution to the controversy over the timing and rate of growth of the Earth’s continents is expected. Anticipated outcomes include the establishment of innovative analytical tools for tracing geological and environmenta ....Testing continental growth models with calcium and strontium isotopes. The Project aims to chart the evolution of the Earth’s primordial mantle and oceans between 3.75 and 2.8 billion years ago using calcium and strontium isotopes in ancient igneous and sedimentary rocks. A novel solution to the controversy over the timing and rate of growth of the Earth’s continents is expected. Anticipated outcomes include the establishment of innovative analytical tools for tracing geological and environmental processes, and stronger collaborative links with premier research institutions abroad. The significant benefits of the Project include an enhanced understanding of the environment in which early life evolved, and fresh insight into the formation of the richly mineralized nucleus of the Australian continent.

Summary
New horizons in geochemical isotopic analysis with a new-generation multicollector plasma mass spectrometer: towards unravelling the deep earth system. A new-generation plasma mass spectrometer will let us develop novel applications in geochemistry to better understand Earth processes. This will enhance Australian Geosciences’ high international profile, and help attract high-quality researchers to attack problems relevant to the Deep Earth Resources National Priority and mineral exploration.

This project will apply compound specific sulfur isotope analyses to sulfur-rich deposits from extreme environments including sulfidic black oozes (Peel-Harvey estuary); modern microbialites (for example, Shark Bay) and oils/source rocks (established and frontier oil fields). Sulfur isotopic data, integrated with other stable isotopic and molecular data, will greatly assist the study of sulfur biogeochemical cycles and mechanisms of organic sulfurisation at different diagenetic stages or geological ages. The project aims to address national concerns through measuring the respective impact of anthropogenic and natural changes on environments, helping to understand the evolution of life on Earth and contributing to efficient discovery of our natural petroleum systems.Read moreRead less
