Sedimentary basins: Windows into the dynamics of Australian lithosphere. This project aims to investigate the structure and stability of the Australian continent. It will focus on improving predictive models of sedimentary basin development on the edge of thick lithosphere, which host large quantities of metal, hydrocarbons, and freshwater.

This project aims to investigate the structure and stability of the Australian continent. It will focus on improving predictive models of sedimentary basin development on the edge of thick lithosphere, which host large quantities of metal, hydrocarbons, and freshwater. Understanding their formation will enhance the ability to locate resources in frontier areas. The research combines state-of-the-art geodynamical modelling with the burgeoning quantity of geophysical and geological data collected by the government and research community. The project would build Australian research capability and stimulate novel approaches to critical problems, highlighting opportunities at the interface between academic and industry geoscience.Read moreRead less

The project aims to develop technologies enabling rapid informed decision-making related to the management of natural resources, including critical metals, copper and water. This new technology will support a greener future, securing our energy future, our access to clean water and reduce the mining footprint. Expected outcomes include an enhanced capability in interoperable, integrated three-dimensional geological and geophysical modelling in order to predictively characterise sub-surface geology. The outcome will be an open-source forecasting dashboard enabling decision making while considering underlying risk related to resource extractions and management with significant benefits to the Australian society (lower emissions, clean water).Read moreRead less
Tracking water on planetary surfaces using data from the Curiosity rover, the laboratory, meteorites and Australian field sites. A fundamental question in science is why does Earth have so much liquid water, but other planets do not? This project will answer this question using the Curiosity rover on Mars, studying alteration minerals that record the action of water. The project will develop new methods to improve our understanding of alteration minerals in martian meteorites, under controlled ....Tracking water on planetary surfaces using data from the Curiosity rover, the laboratory, meteorites and Australian field sites. A fundamental question in science is why does Earth have so much liquid water, but other planets do not? This project will answer this question using the Curiosity rover on Mars, studying alteration minerals that record the action of water. The project will develop new methods to improve our understanding of alteration minerals in martian meteorites, under controlled environmental conditions and in field samples that are relevant for Mars. It aims to build expertise in the environmental aspects of planetary surfaces and in novel instrumentation. This research will improve methods to examine returned extraterrestrial samples, to evaluate land degradation and to search for energy and ore deposits.Read moreRead less
Biogeochemistry of ferruginous duricrusts. The project is focussed on the examination and application of microbial iron cycling in the formation of geologically stable, iron duricrusts in tropical regimes. The aim of the project is to develop a site-scale bioremediation strategy for iron ore mines by re-establishing canga, which are ‘ancient’ distinct ecosystems possessing unique plant species rarely found on Earth. This university-industry collaboration aims to produce economic benefits for the ....Biogeochemistry of ferruginous duricrusts.

The aim of the project is to develop a site-scale bioremediation strategy for iron ore mines by re-establishing canga, which are ‘ancient’ distinct ecosystems possessing unique plant species rarely found on Earth. This university-industry collaboration aims to produce economic benefits for the world’s iron mining industry through advanced training in mining-related research, and through the completion of the mining life cycle by site remediation, enhancing Australia’s position as a global leader in providing innovative solutions to today’s mining challenges.Read moreRead less
The geochemical role of iron in basaltic magmatism and planetary differentiation: an experimental study. The amount of Fe in primitive terrestrial basalts is surprisingly variable. The reasons for this are poorly understood, but could include melting of Fe-enriched refertilized mantle sources, increasing partitioning of FeO into the melt with depth of melting, or oxidation of some FeO to Fe2O3. An experimental investigation of the effects of Fe both as 2+ and 3+ on the partial melting of model ....The geochemical role of iron in basaltic magmatism and planetary differentiation: an experimental study. The amount of Fe in primitive terrestrial basalts is surprisingly variable. The reasons for this are poorly understood, but could include melting of Fe-enriched refertilized mantle sources, increasing partitioning of FeO into the melt with depth of melting, or oxidation of some FeO to Fe2O3. An experimental investigation of the effects of Fe both as 2+ and 3+ on the partial melting of model mantle material should help resolve this problem, while also providing the fundamental thermodynamic data needed to calibrate a general model for upper mantle phase relations.Read moreRead less
Chemical influences on the seismic structure of the Earth's upper mantle. This project aims to determine the sensitivity of the seismic properties of Earth’s upper mantle (to 400 km depth) to variations in the prevailing chemical environment. The unique capability of the ANU Rock Physics Laboratory for low-frequency measurement of wave speeds and attenuation will be exploited to clarify the newly discovered importance of redox conditions, and document the effect of varying proportions of the mos ....Chemical influences on the seismic structure of the Earth's upper mantle. This project aims to determine the sensitivity of the seismic properties of Earth’s upper mantle (to 400 km depth) to variations in the prevailing chemical environment. The unique capability of the ANU Rock Physics Laboratory for low-frequency measurement of wave speeds and attenuation will be exploited to clarify the newly discovered importance of redox conditions, and document the effect of varying proportions of the most abundant upper-mantle minerals olivine and pyroxene. The expected outcome will be a robust and comprehensive model to guide the interpretation of the complex architecture of the upper mantle, and thereby provide an improved understanding of the tectonic processes responsible for its evolution through geological time.Read moreRead less
