The lost ocean of eastern Australia and its critical metals endowment. This project aims to unravel the tectonic origin and economic potential of ultramafic rocks (rocks which host elevated concentrations of nickel, cobalt, chromium, and platinum-group elements). Such rocks are outcropping in eastern Australia along a contorted ~1500 km long belt that may record relics of an ancient ocean. Through detailed mapping and cutting-edge analytical techniques, the project is expected to fill a crucial ....The lost ocean of eastern Australia and its critical metals endowment. This project aims to unravel the tectonic origin and economic potential of ultramafic rocks (rocks which host elevated concentrations of nickel, cobalt, chromium, and platinum-group elements). Such rocks are outcropping in eastern Australia along a contorted ~1500 km long belt that may record relics of an ancient ocean. Through detailed mapping and cutting-edge analytical techniques, the project is expected to fill a crucial knowledge gap in Australian tectonics, while providing information on ore mineralisation. The expected outcomes, including new tectonic models unveiling the scale, geometry, and economic potential of the ultramafic bodies, could benefit critical mineral exploration, carbon storage solutions, and geoecology conservation.Read moreRead less
Hydrogen generation by subsurface iron mineral transformations. Aim

The aim of this project is to elucidate key factors responsible for natural hydrogen generation in Australian subsurface environments.
Significance
Large amounts of this valuable resource are produced naturally with estimates of production rates of this “gold” hydrogen at least 100 times the annual demand for this critical resource.
Expected Outcomes
Based on improved understanding of the source of natural hydrogen, predictive tools will be developed that will assist in assessing the viability in Australia of hydrogen exploration and engineered retrieval.
Benefits
Ready access to naturally produced hydrogen could enable Australia to replace hydrogen that is currently generated via the use of unabated hydrocarbons.Read moreRead less
Reconstructing the Beetaloo/Greater McArthur Basin System . This project aims to build a stratigraphic and water chemistry framework for the greater McArthur Basin—a rock system that covers northern Australia from WA to Queensland. This will be a vital resource for researchers and energy/mineral explorers. This project expects to develop novel sediment dating and isotopic proxies for salinity, redox and bioproductivity and use them to build a sequence stratigraphic framework of the basin. The ex ....Reconstructing the Beetaloo/Greater McArthur Basin System . This project aims to build a stratigraphic and water chemistry framework for the greater McArthur Basin—a rock system that covers northern Australia from WA to Queensland. This will be a vital resource for researchers and energy/mineral explorers. This project expects to develop novel sediment dating and isotopic proxies for salinity, redox and bioproductivity and use them to build a sequence stratigraphic framework of the basin. The expected outcome is a unique 3D lithological, geochronological and geochemical framework for the basin. Expected benefits include de-risked information for the petroleum and minerals industry, assisting northern Australia's resources economy, as well as insights into the development of our planet in deep time.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.

Mapping mineral systems of deep Australia. We aim at enabling mineral resource discoveries by calibrating geophysical surveys using geochemical and petrophysical properties measured on mantle samples brought to the surface by recent volcanoes. National geophysical surveys deliver images of geophysical gradients in the deeper part of the Australian continent. The interpretation of these gradients in geological terms and in terms of economic mineral systems is the key to unlock deep exploration su ....Mapping mineral systems of deep Australia. We aim at enabling mineral resource discoveries by calibrating geophysical surveys using geochemical and petrophysical properties measured on mantle samples brought to the surface by recent volcanoes. National geophysical surveys deliver images of geophysical gradients in the deeper part of the Australian continent. The interpretation of these gradients in geological terms and in terms of economic mineral systems is the key to unlock deep exploration success. This project will turn Australia’s investment in National geophysical surveys into new discoveries of base metals. The benefit stems from enabling the transition to a clean economy which requires a much broader range of critical minerals and a larger quantity of base metals.Read moreRead less
A terrestrial hot spring setting for the origin of life. This project aims to test the proposal that a terrestrial hot spring field could have been the setting for the origin of life, in preference over the currently favoured site at deep sea vents. The project will involve an integrated, and multi-disciplinary study of the rocks, fluids, and molecules that together make up ancient to modern hot spring systems, and experiments on prebiotic organic chemistry using early Earth materials. Results w ....A terrestrial hot spring setting for the origin of life.

Experimental and empirical insight into melting of the early Earth's mantle. The early Earth's mantle produced melt at much higher temperature than today, creating rocks with unique chemistries and mineralogies. But pressing knowledge gaps about hot mantle melting remain. The aim of this project is to generate new experimental and empirical knowledge to help closing these gaps by:
(i) conducting high pressure experiments to refine phase-composition relationships and element partitioning;

The early Earth's mantle produced melt at much higher temperature than today, creating rocks with unique chemistries and mineralogies. But pressing knowledge gaps about hot mantle melting remain. The aim of this project is to generate new experimental and empirical knowledge to help closing these gaps by:
(i) conducting high pressure experiments to refine phase-composition relationships and element partitioning;
(ii) quantifying mineral fabrics in cratonic peridotites to understand the movement of early continents; and
(iii) constructing the first petrological deep time model for greenstone belt volcanic rocks.
The expected outcomes are better models for the early Earth's melting and tectonic regimes and insight into the emergence of land.Read moreRead less

This project aims to constrain the timing and speed of the Cambrian radiation of complex animals, and to test potential environmental triggers of this milestone bioevent. New laser mass spectrometry and mineral mapping technology will be integrated to precisely date glauconite – a silicate mineral commonly formed in Cambrian shallow marine animal habitats. This innovative and cost-effective approach will produce the first high-resolution timeline of early animal evolution, where the glauconite-based marine isotope record identifies the most likely environmental trigger for the Cambrian Radiation. Outcomes of this study include improved understanding of the drivers of animal evolution, and a new dating tool for basic and applied research.Read moreRead less
