The dynamic strength of continents and how they break apart. Sedimentary basins formed as a result of continental extension are the source of many oil and gas and geothermal resources. The geometries of the deepest part of these basins and their temporal and thermal evolution, are essential for basin prospectivity, but can seldom be investigated directly.

Sedimentary basins formed as a result of continental extension are the source of many oil and gas and geothermal resources. The geometries of the deepest part of these basins and their temporal and thermal evolution, are essential for basin prospectivity, but can seldom be investigated directly. This Australia-based project is expected to overhaul how we understand continental deformation, which is a crucial, but relatively vaguely understood, component of plate tectonics. By modelling continental extension, the project will improve our understanding of basin development, deep geometry, and heat distribution, providing the basis for new applied and specific research projects directed at enhancing energy resource exploration.

Origin of jaws - the greatest unsolved mystery of early vertebrate evolution. The 2008 discovery of an unborn embryo in the 380 million-year-old "Mother Fish" from the famous Gogo fossil deposit in NW Australia has attracted a collaboration of Australian, American and Chinese scientists to a new international collaboration. The team will study spectacular new fossils from central Australia and southern China, the oldest known back-boned animals with jaws and a hard skeleton.

The 2008 discovery of an unborn embryo in the 380 million-year-old "Mother Fish" from the famous Gogo fossil deposit in NW Australia has attracted a collaboration of Australian, American and Chinese scientists to a new international collaboration. The team will study spectacular new fossils from central Australia and southern China, the oldest known back-boned animals with jaws and a hard skeleton. Innovative 3D X-ray computer tomography, and the Australian synchrotron, will be used to investigate ancient cells and preserved soft tissue structures, to search for evidence that copulation and internal fertilization, as in modern mammals, might have originated when jaws first evolved.

Accessory Mineral Microstructure and Implications for Geochronology. U-Pb geochronology of accessory minerals is widely used to constrain the timing of igneous, metamorphic and sedimentary processes. However, our current knowledge of isotope mobility in these important minerals cannot readily explain some common features of U-Pb dating. Using new developments in quantitative microstructural analysis integrated with high spatial resolution geochronology we will constrain the relationship between ....Accessory Mineral Microstructure and Implications for Geochronology. U-Pb geochronology of accessory minerals is widely used to constrain the timing of igneous, metamorphic and sedimentary processes. However, our current knowledge of isotope mobility in these important minerals cannot readily explain some common features of U-Pb dating. Using new developments in quantitative microstructural analysis integrated with high spatial resolution geochronology we will constrain the relationship between accessory minerals deformation and its effect on radiometric ages. Our results will lead to a better understanding of geochemical modification of accessory minerals and may lead to the development of new applications of geochronology and improve the dating of rock deformation.Read moreRead less

Summary
A new nano-geochronology approach to global Earth processes. This project aims to develop a new nano-geochronology tool. Geochronology is the science of determining the ages of rocks and geological events, and is key to answering fundamental questions of planetary evolution, the geological processes that shaped our Earth, and evolution of life and past climates. Many valuable mineral phases are too small to be dated by conventional methods. The potential that nano-geochronology has to unlock inf ....A new nano-geochronology approach to global Earth processes. This project aims to develop a new nano-geochronology tool. Geochronology is the science of determining the ages of rocks and geological events, and is key to answering fundamental questions of planetary evolution, the geological processes that shaped our Earth, and evolution of life and past climates. Many valuable mineral phases are too small to be dated by conventional methods. The potential that nano-geochronology has to unlock information otherwise untraceable remains largely unexplored. The development and application of nano-geochronology will improve our understanding of the Australian crust and the field of geological mapping, which largely supports mineral exploration.Read moreRead less
Mineral reaction, deformation, and accessory phases in migmatites: What controls monazite behaviour during high-grade metamorphism? Isotopic dating of rocks and minerals has revolutionized the way we view our planet, and allowed us to attach an absolute timescale to a range of Earth processes from the evolution of life to formation of mineral deposits. Australian technology has long been at the forefront of this field, but it is apparent that our ability to date Earth materials has overtaken our ....Mineral reaction, deformation, and accessory phases in migmatites: What controls monazite behaviour during high-grade metamorphism? Isotopic dating of rocks and minerals has revolutionized the way we view our planet, and allowed us to attach an absolute timescale to a range of Earth processes from the evolution of life to formation of mineral deposits. Australian technology has long been at the forefront of this field, but it is apparent that our ability to date Earth materials has overtaken our ability to interpret these ages in terms of geologic processes. The results of this study and the associated collaboration will ensure that Australian understanding of what isotopic ages mean keeps pace with our ability to measure them. This will allow us to resolve finer details of Earth history, and improve our understanding of the planet and how best to manage it.Read moreRead less
Integrated provenance analysis: towards better ways of interpreting the source of ancient sediments. Determining the provenance of sedimentary grains is a key element of testing competing geological hypotheses.

Determining the provenance of sedimentary grains is a key element of testing competing geological hypotheses. Most provenance analyses are based on single-grain analytical techniques that may miss vital information. This project will develop an integrated, systematic approach to provenance analysis by applying a broad range of modal, geochemical and isotopic techniques to enable the effective identification of sources of grains in sedimentary rocks. The new system will be used to test hypotheses of when the Pilbara and Yilgarn cratons amalgamated to form the core of the Australian continent.Read moreRead less
