Water is essential for human existence, indeed for life's beginning. The circulation of water between the surface and the deep interior lubricates the internal dynamics that keep Earth geologically alive; it is crucial to most Earth systems, including the evolution of the hydrospher/atmosphere/biosphere, and the development of giant ore deposits. However, the origin, abundance, speciation and movements of fluids inside Earth are largely unknown, and represent key issues in modern geoscience. This CoE will integrate previously disparate fields - geology, tectonics, geochemistry, petrophysics, geophysics and dynamic modelling - to understand the workings of Earth's deep plumbing system.Read moreRead less
Unlocking Earth’s inner secrets in deep time using palaeointensities. The geomagnetic field, generated in Earth's liquid outer core, provides Earth's biosphere and atmosphere with a critical protective shield from the bombardment of the solar wind. However, we still know little about the evolution of the geomagnetic field or the deep-time secrets it keeps. This project aims to study the varying intensity of the geomagnetic field during Earth’s middle life. The results will help decipher how the ....Unlocking Earth’s inner secrets in deep time using palaeointensities. The geomagnetic field, generated in Earth's liquid outer core, provides Earth's biosphere and atmosphere with a critical protective shield from the bombardment of the solar wind. However, we still know little about the evolution of the geomagnetic field or the deep-time secrets it keeps. This project aims to study the varying intensity of the geomagnetic field during Earth’s middle life. The results will help decipher how the Earth’s core responded to evolving tectonic and dynamic systems, including the supercontinent cycles, and when Earth’s solid inner core initiated. Such knowledge will help us to better understand how the Earth System evolved as a whole, and how such an evolution has led to the present day life and environment on Earth.Read moreRead less

How the Earth works - toward building a new tectonic paradigm: This fellowship project aims to build on the latest technological and conceptual advances to establish the patterns of Earth evolution, and use this information to examine a ground-breaking geodynamic hypothesis which links cyclic plate aggregation and dispersion to deep Earth processes.

How the Earth works - toward building a new tectonic paradigm: This fellowship project aims to build on the latest technological and conceptual advances to establish the patterns of Earth evolution, and use this information to examine a ground-breaking geodynamic hypothesis which links cyclic plate aggregation and dispersion to deep Earth processes. Half a century after the inception of plate tectonics theory, we are still unsure how the Earth 'engine' works, particularly the forces that drive plate tectonics. The project involves extensive national and international collaboration to potentially create a paradigm shift in our understanding of global tectonics, and hopes to contribute to an understanding of the formation and distribution of Earth resources to provide a conceptual framework for their exploration.Read moreRead less
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.

A fully automated, fully shielded palaeomagnetic system: This project aims to establish the first fully automated and magnetically fully shielded superconducting palaeomagnetic data acquisition system in Australia. Palaeomagnetism is a key research field that has applications to a broad range of pure and applied geoscience disciplines. Australia has been a world leader in this field, including the application of palaeomagnetism to both global and regional tectonic studies. Palaeomagnetic studies demand a labour-intensive process of treating and measuring a large number of samples. The system will significantly enhance the efficiency and accuracy of palaeomagnetic analysis, and thus enhance Australia's research capacity in this and related research fields.Read moreRead less
Add mountains and shake: plate boundary fault and earthquake patterns. This project aims to determine the fundamental physical processes that link topography, seismic shaking and volcanism to the evolution of seismogenic fault networks in obliquely convergent (transpressional) plate boundary settings. We will combine detailed field and remote sensing-based structural analyses in transpressional mountain belts with advanced laboratory analogue and numerical experiments to evaluate: 1) how bursts ....Add mountains and shake: plate boundary fault and earthquake patterns. This project aims to determine the fundamental physical processes that link topography, seismic shaking and volcanism to the evolution of seismogenic fault networks in obliquely convergent (transpressional) plate boundary settings. We will combine detailed field and remote sensing-based structural analyses in transpressional mountain belts with advanced laboratory analogue and numerical experiments to evaluate: 1) how bursts of strong seismic shaking perturb fault zone evolution through time; 2) the contribution of topography and gravitation loading to fault interactions and earthquake generation; and 3) feedbacks between fault network development, the spatial distribution of volcanic centres, seismic shaking and ore deposits.Read moreRead less
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.

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.
