Quantifying the Phanerozoic thermal evolution and long-term stability of cratonic lithosphere using integrated low temperature thermochronology. The Earth's most ancient crustal regions (i.e. cratons) are thought to have remained remarkably stable since their formation >2.5 billion years ago. This project will re-evaluate this paradigm by applying low temperature thermochronology by the fission track and (U-Th)/He methods to three key cratons, to detect and quantify previously unknown episodes o ....Quantifying the Phanerozoic thermal evolution and long-term stability of cratonic lithosphere using integrated low temperature thermochronology. The Earth's most ancient crustal regions (i.e. cratons) are thought to have remained remarkably stable since their formation >2.5 billion years ago. This project will re-evaluate this paradigm by applying low temperature thermochronology by the fission track and (U-Th)/He methods to three key cratons, to detect and quantify previously unknown episodes of significant cooling and denudation (i.e. low-level instability) which are invisible to other analytical techniques. The outcomes will open a new research avenue in these terrains, which host some of the world's most valuable mineral resources, underlie important petroleum basins and are potential long-term repositories for radioactive waste.

From crystal to craton: unravelling the low-temperature thermal evolution and long-term stability of cratonic lithosphere. The project will expand Australia's knowledge base by increasing fundamental scientific knowledge about the evolution of cratons, the old nuclei of the continents. These areas are important for the resources they contain and their potential elsewhere as stable sites for long-term nuclear waste repositories. The project will also enhance our research capability by developin ....From crystal to craton: unravelling the low-temperature thermal evolution and long-term stability of cratonic lithosphere. The project will expand Australia's knowledge base by increasing fundamental scientific knowledge about the evolution of cratons, the old nuclei of the continents. These areas are important for the resources they contain and their potential elsewhere as stable sites for long-term nuclear waste repositories. The project will also enhance our research capability by developing new methods and help to build and sustain world leading research capability in Australia. In addition, the project will forge strong international links with researchers overseas. Whilst not focussed directly on the National Research Priorities the project will nonetheless provide important background information to 'deep-earth resources' and 'geoinformatics'.Read moreRead less
Reconstructing the morphotectonic evolution of rifted continental margins from low-temperature thermochronology. Knowledge of how continental rifting occurs will improve our ability to predict the locations of important oil and gas resources on the margins of Australia and elsewhere, which is directly relevant to the National Research Priority goal of 'Developing Deep Earth Resources'. The project will enhance our national scientific standing by developing and maintaining key expertise and facil ....Reconstructing the morphotectonic evolution of rifted continental margins from low-temperature thermochronology. Knowledge of how continental rifting occurs will improve our ability to predict the locations of important oil and gas resources on the margins of Australia and elsewhere, which is directly relevant to the National Research Priority goal of 'Developing Deep Earth Resources'. The project will enhance our national scientific standing by developing and maintaining key expertise and facilities that can sustain a world-leading research capability in Australia. The project will also forge strong international links with researchers outside Australia, build our research profile in an area of significant worldwide scientific interest at the present time, and provide a training ground for a new generation of younger scientists in Australia.Read moreRead less
Integrated Chronologies and Dynamics of Continental Extension. Knowledge about how the Earth's crust is stretched and eventually broken apart to form new ocean basins is fundamental to understanding the evolution of the continents, their resources and the surface environment of our planet. This project combines new methods of analysing the temperature history of rocks to trace their progress towards the surface with direct measurements of the rate of surface erosion following extensional moveme ....Integrated Chronologies and Dynamics of Continental Extension. Knowledge about how the Earth's crust is stretched and eventually broken apart to form new ocean basins is fundamental to understanding the evolution of the continents, their resources and the surface environment of our planet. This project combines new methods of analysing the temperature history of rocks to trace their progress towards the surface with direct measurements of the rate of surface erosion following extensional movements. This integrated approach will be used to examine some of the best-characterised examples of continental extension in Arizona, Mexico and Africa to cast new light on the development of older extensional environments in Australia.Read moreRead less

The study is therefore relevant to the National Research Priority goal of 'Developing Deep Earth Resources'. The project will also enhance our national scientific standing by addressing important scientific questions of global significance, and by establishing strong international collaborations with prominent researchers outside Australia. In addition, the work will help sustain a world-leading research capability and provide a training ground for a new generation of younger scientists in Australia.Read moreRead less

Geodynamic evolution of the Banda Arc. The project will contribute to a better understanding of plate tectonic processes and will provide insights into the dynamics of the Indo-Australian plate. This information is fundamentally important for estimating seismic hazards and the potential for generating large magnitude earthquakes in Australia.

The project will contribute to a better understanding of plate tectonic processes and will provide insights into the dynamics of the Indo-Australian plate. This information is fundamentally important for estimating seismic hazards and the potential for generating large magnitude earthquakes in Australia. Outcomes of this project will facilitate to unravel analogue tectonic systems that were active during the geological evolution of Australia (e.g. the Lachlan fold belt in eastern Australia), thus providing a new insight into the Australian environment. The project will also elucidate the nature of tectonic processes that are known to generate major ore deposits and is therefore likely to have important economic implications.Read moreRead less
