The link between cratonic roots, redox state, and mantle geodynamics. This project aims to understand the role of Earth's redox state on the geodynamic evolution of continental cratonic roots. Cratonic roots form strong, buoyant rafts upon which Australia's oldest crust and mineral deposits survived. Cratons preserve a record of planetary-scale chemical shifts, including the rise of surface oxygen, but it is unclear how these redox shifts themselves affected lithospheric processes.

This project aims to understand the role of Earth's redox state on the geodynamic evolution of continental cratonic roots. Cratonic roots form strong, buoyant rafts upon which Australia's oldest crust and mineral deposits survived. Cratons preserve a record of planetary-scale chemical shifts, including the rise of surface oxygen, but it is unclear how these redox shifts themselves affected lithospheric processes. This project integrates new developments in geochemistry, geophysics, and geodynamics, to map the geochemical state and structure of cratonic roots, aiding mineral exploration, and also shedding light on the processes that modify, mineralise, and sometimes destroy cratonic roots.Read moreRead less
Unveiling the fine structure of the Australian continent using ocean waves. This project aims to develop new methods to better image lithospheric and upper-mantle structures by using noise from ubiquitous ocean waves, and then use these methods to illuminate fine-scale lithospheric-asthenospheric structures in Australia, from the surface to the upper mantle. Imaging the Earth’s structure using seismic tomography is one of the most fundamental tasks of geoscience. Conventional earthquake-based se ....Unveiling the fine structure of the Australian continent using ocean waves. This project aims to develop new methods to better image lithospheric and upper-mantle structures by using noise from ubiquitous ocean waves, and then use these methods to illuminate fine-scale lithospheric-asthenospheric structures in Australia, from the surface to the upper mantle. Imaging the Earth’s structure using seismic tomography is one of the most fundamental tasks of geoscience. Conventional earthquake-based seismic tomography has difficulties in deciphering fine-scale lithospheric structures. The images from this project will provide a better understanding of the nature of intraplate earthquakes and volcanoes, and improve the assessment of intraplate seismic and volcanic hazards in Australia.Read moreRead less
Measuring mantle hydrogen to map ore fluids and model plate tectonics. The goal of this project is to use magnetotellurics to measure mantle hydrogen content to aid in the discovery of new mineral deposits. Hydrogen controls the strength of Earth’s mantle and is a vital component of the systems that form giant ore deposits. However, mantle hydrogen content is unconstrained. Ore-forming fluids hydrate the mantle pathways on which they travel. The first aim of this project is to image these fluid ....Measuring mantle hydrogen to map ore fluids and model plate tectonics. The goal of this project is to use magnetotellurics to measure mantle hydrogen content to aid in the discovery of new mineral deposits. Hydrogen controls the strength of Earth’s mantle and is a vital component of the systems that form giant ore deposits. However, mantle hydrogen content is unconstrained. Ore-forming fluids hydrate the mantle pathways on which they travel. The first aim of this project is to image these fluid pathways to improve mineral exploration techniques. Plate tectonic models assume that the lithospheric mantle is dehydrated but existing data from magnetotellurics and mantle rocks show high hydrogen contents. The second aim of this project is to create a map of the hydrogen content of the plates, which may lead to new models for continental evolution and mantle dynamics.Read moreRead less
Dynamic Earth Models for Frontier Mineral Exploration. This Project aims to investigate the link between supercontinents, mantle upwelling, and associated mineral resources by combining reconstructions of mantle flow with the global rock record. Mantle upwelling causes eruptions of volcanic provinces and associated rock formations that are rich in minerals. The expected outcomes of the Project include mapping the global potential for magmatic nickel, rare-earth elements, and diamond deposits fro ....Dynamic Earth Models for Frontier Mineral Exploration. This Project aims to investigate the link between supercontinents, mantle upwelling, and associated mineral resources by combining reconstructions of mantle flow with the global rock record. Mantle upwelling causes eruptions of volcanic provinces and associated rock formations that are rich in minerals. The expected outcomes of the Project include mapping the global potential for magmatic nickel, rare-earth elements, and diamond deposits from 1.8 billion years ago and building a research alliance between the University of Wollongong, Anglo American, and De Beers. Significant benefits will be the development of a digital framework to reduce risks in exploration for minerals that are essential for the transition to a low-carbon economy.Read moreRead less
Enhanced 3-D seismic structure for Southwest Australia. The ancient cratonic lithosphere of Southwest Australia appears to have a distinct contrast in geophysical properties and complex geologic structure, while having some of the highest levels of earthquakes on the continent. The project aims to produce novel 3-D models of this region that combine new seismic data collected over two years with previously collected geophysical datasets from the partner investigators. A compilation of 3-D models ....Enhanced 3-D seismic structure for Southwest Australia. The ancient cratonic lithosphere of Southwest Australia appears to have a distinct contrast in geophysical properties and complex geologic structure, while having some of the highest levels of earthquakes on the continent. The project aims to produce novel 3-D models of this region that combine new seismic data collected over two years with previously collected geophysical datasets from the partner investigators. A compilation of 3-D models will subsequently be developed, to form an effective characterisation of the geologic structure of the craton and its margins. These models will provide enhanced assessment of seismic ground shaking from regional earthquakes and facilitate an improved understanding of mineral resource potential. Read moreRead less

Demand for critical minerals will soar as renewable energy generation increases, but exploration companies currently cannot take full advantage of available exploration data in an Earth evolution context. This project will generate new knowledge in big and complex geodata analysis using an innovative data mining approach. It will enable Lithodat, a small enterprise, to perform cloud-based plate tectonic reconstruction, visualisation and spatio-temporal analysis of geodata for resource exploration. The outcomes include an enhanced capacity to generate ore prospectivity maps and an improved understanding of their tectonic, geochemical, and geophysical signatures, benefiting Lithodat and their clients in the search for new mineral deposits.Read moreRead less
