Four dimensional lithospheric evolution and controls on mineral system distribution in Neoarchean to Paleoproterozoic terranes. This project will resolve important questions about the links between the evolution and preservation of continents and important mineral deposits in Australia and West Africa between 2.7 and 1.8 billion years ago. The results will improve the understanding of a key period of Earth history and make a major contribution to mineral exploration.
Resolving the influence of intraplate orogenesis on continental margin tectonics. Novel, multi-dating of continental sedimentary rocks will be undertaken to examine the effects of a high sediment flux from an enigmatic, major mountain-building event on a distant continental margin. This will expand our understanding of the range of tectonic influences between continental interiors and margins and onshore resource potential.

Summary
Exploring links between climate change, ocean chemistry, and the rise of multicellular life: The Ediacaran sedimentary record of central Australia. For most of Earth’s history, single-celled organisms were the only forms of life on the planet. Not until roughly 600 million years ago do fossils of multicellular animals appear in the rock record. Explanations for the Ediacaran rise of multicellularity include extreme climate change, meteorite impact and oxygenation of the global ocean.

For most of Earth’s history, single-celled organisms were the only forms of life on the planet. Not until roughly 600 million years ago do fossils of multicellular animals appear in the rock record. Explanations for the Ediacaran rise of multicellularity include extreme climate change, meteorite impact and oxygenation of the global ocean. Evaluation of these hypotheses is complicated by the fact that stratigraphic records that span the appropriate time interval are rare. This project is focused on the carbon, oxygen, and zinc isotopic records preserved by Ediacaran marine rocks in the Amadeus Basin of central Australia. Results will contribute to a more complete record of fluctuations in ocean chemistry during a key interval of Earth history.Read moreRead less

Summary
A world-class rock magnetic facility to support Australian palaeomagnetic and environmental research. Magnetic properties of rocks and environmental particles provide information about a vast range of geological and environmental processes. We propose to develop a facility that will enable detection and interpretation of these magnetic signals to aid understanding of climate change, mineral exploration, and the geological development of Australia.
Multiple vertical tectonic movements in a continental interior: consequences of flat-subduction and foundering of an oceanic plateau? This project will investigate how the subduction of particularly thick oceanic crust impacts on the landscape, climate, structure and composition of the adjacent continent. It will help in understanding the history and distribution of mineral and hydrocarbon resources, of similar provinces in Australia.
Unravelling the geodynamics of eastern Australia during the Permian: the link between plate boundary bending and basin formation. Using paleomagnetic and sedimentological investigations, this project will unravel the Permian tectonic history of eastern Australia, which has hitherto remained poorly understood. The reconstruction will provide a crucial component in our attempt to model the evolution of the Australian continent and its associated natural resources.
Deep time in the deep Earth: using trace element diffusivities to constrain durations of deep Earth processes. Evaluation of deep Earth resources requires knowing how long geological processes took, some record of which is often preserved by gradients in the chemical compositions of minerals. Experiments at very high temperatures and pressures will determine how this evidence can be used to constrain the durations of a rich variety of geological processes.
