Summary
Linking continental emergence and climatic evolution on the Early Earth. This project will use a range of innovative geochemical techniques to constrain the timing and extent to which the continents were emergent (above sea-level) throughout Earth’s history and its impact on climatic evolution. Continental emergence was pivotal to the development of our habitable planet, as it controlled the influx of bioessential elements, like phosphorus, to the oceans. Expected outcomes include a detailed rec ....Linking continental emergence and climatic evolution on the Early Earth. This project will use a range of innovative geochemical techniques to constrain the timing and extent to which the continents were emergent (above sea-level) throughout Earth’s history and its impact on climatic evolution. Continental emergence was pivotal to the development of our habitable planet, as it controlled the influx of bioessential elements, like phosphorus, to the oceans. Expected outcomes include a detailed record of changes in ocean chemistry, and a time integrated model for the emergence of continents on the early Earth. Documenting the impact of changes in the solid Earth on evolution is not only of interest to society in general, but also contributes to understanding the formation of Australia’s vast iron ore deposits.Read moreRead less
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
