The lost ocean of eastern Australia and its critical metals endowment (2023–2026)
Abstract:
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.
