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

This project will deliver a new quantitative and integrated exploratory framework for the mineral industry in Australia’s frontier sedimentary basins by integrating the latest advances in laboratory experimental tectonics with thermo-mechanical numerical, surface process and geophysical modelling. The project will use northern Australian basins as a natural laboratory to address the fundamental processes involved in the development of sedimentary ore systems. The project will investigate how they can be detected by modern exploration techniques using a multidisciplinary approach with a team of experts with backgrounds in mineral and petroleum systems.

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 diamond exploration. This project aims to investigate the link between continent motion and mantle upwelling over the last billion years by combining tectonic reconstructions and recently developed dynamic earth models with the global and Australian rock record. Mantle upwelling is thought to cause eruptions of large volcanic provinces and kimberlites, the primary source rock for diamonds. The project expects to develop a technique to map kimberlite potential in ....Dynamic earth models for frontier diamond exploration. This project aims to investigate the link between continent motion and mantle upwelling over the last billion years by combining tectonic reconstructions and recently developed dynamic earth models with the global and Australian rock record. Mantle upwelling is thought to cause eruptions of large volcanic provinces and kimberlites, the primary source rock for diamonds. The project expects to develop a technique to map kimberlite potential in under-explored regions such as Australia. Significant benefits from the project will be the reduction of economic risks in diamond exploration, the training of a researcher in exploration geodynamics, and understanding the link between supercontinents and mantle upwelling.Read moreRead less

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.

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
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

Summary
Hunting high and low: mapping ancient topography to find copper. Transitioning to a decarbonised society requires significant amounts of copper; however, preventing a systems-based exploration approach for copper is the lack of a first-order dataset of the Earth’s surface evolution, known as palaeogeography. This project aims to unearth potential areas of porphyry copper through deep time by developing innovative global palaeogeography reconstructions. Expected outcomes of this project include n ....Hunting high and low: mapping ancient topography to find copper. Transitioning to a decarbonised society requires significant amounts of copper; however, preventing a systems-based exploration approach for copper is the lack of a first-order dataset of the Earth’s surface evolution, known as palaeogeography. This project aims to unearth potential areas of porphyry copper through deep time by developing innovative global palaeogeography reconstructions. Expected outcomes of this project include new quantitative palaeogeography reconstructions, as well as the first well-constrained reconstructions of copper preservation potential. This should provide benefits such as an improved understanding of the porphyry copper lifecycle, with significant impacts for resource exploration and decarbonisation efforts.Read moreRead less
