Australia's astronomers are exceptionally well placed to lead and to partner with major international programs in Antarctic astronomy. These bring Australian industry increased access to cutting-edge technology, and create business opportunities in the infrastructure and support of Antarctic research. This project aims to maintain Australia's lead in Antarctic astronomy and, with the inclusion of a new partnership with Japan, to build upon our existing strong collaboration with China and the USA. Australia's participation in this program also ensures continued technology exchange, and builds our knowledge base in robotics, harsh-environment engineering and computational fluid dynamics, while creating important new astronomical opportunities.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
Metamorphism, fluid flow, anatexis and the petrogenesis of peraluminous magmas: constraints from boron and lithium elemental and isotopic geochemistry. Boron (B) and lithium (Li) elemental and isotopic variations are sensitive monitors of metamorphism, fluid flow and melting; the generation of granites; and hydrothermal alteration. However, in detail B- and Li- geochemistry are poorly understood. This project uses field-based, analytical and experimental techniques to constrain B and Li elementa ....Metamorphism, fluid flow, anatexis and the petrogenesis of peraluminous magmas: constraints from boron and lithium elemental and isotopic geochemistry. Boron (B) and lithium (Li) elemental and isotopic variations are sensitive monitors of metamorphism, fluid flow and melting; the generation of granites; and hydrothermal alteration. However, in detail B- and Li- geochemistry are poorly understood. This project uses field-based, analytical and experimental techniques to constrain B and Li elemental and stable isotope variations in order to better understand high-temperature metamorphism, fluid flow, melting and the generation of granites and pegmatites. The results of this project will greatly increase our understanding of B and Li systematics in high-temperature crustal environments, and have implications for a range of metamorphic and igneous processes.Read moreRead less

Completion of the Tasman International Geospace Environment Radar (TIGER). TIGER is part of an international high frequency radar consortium (SuperDARN) studying the coupling of space weather processes to the ionosphere. This is critical for radio, navigation and surveillance networks. TIGER provides important new information because it extends the global radar coverage significantly equatorward, and it can be combined with other radars in Antarctica and Alaska. However, only one of the two T ....Completion of the Tasman International Geospace Environment Radar (TIGER). TIGER is part of an international high frequency radar consortium (SuperDARN) studying the coupling of space weather processes to the ionosphere. This is critical for radio, navigation and surveillance networks. TIGER provides important new information because it extends the global radar coverage significantly equatorward, and it can be combined with other radars in Antarctica and Alaska. However, only one of the two TIGER radars necessary to carry out these studies has been built. This proposal is for completion of the second radar, to be located in New Zealand. The US Air Force has already granted A$443k toward this project.Read moreRead less
How has the continental lithosphere evolved? Processes of assembly, growth, transformation and destruction. We will use new in-situ analytical techniques, developed In-house, to date the formation and modification of specific volumes of the subcontinental lithospheric mantle, and to define the temporal and genetic relationships between mantle events and crustal formation. Quantitative modelling will investigate the geodynamic consequences of spatial and temporal variations in lithosphere composi ....How has the continental lithosphere evolved? Processes of assembly, growth, transformation and destruction. We will use new in-situ analytical techniques, developed In-house, to date the formation and modification of specific volumes of the subcontinental lithospheric mantle, and to define the temporal and genetic relationships between mantle events and crustal formation. Quantitative modelling will investigate the geodynamic consequences of spatial and temporal variations in lithosphere composition and thermal state. Magmatic products will be used to assess the roles of mantle plumes and delamination in construction of the lithosphere and xenolith studies will investigate the evolution of oceanic plateaus. The results will provide a framework for interpreting the architecture of lithospheric terranes and their boundaries.Read moreRead less
How has continental lithosphere evolved? Processes of assembly, growth, transformation and destruction. Novel in-situ analytical and dating techniques will be used on samples from the Earth's mantle and deep crust to define the processes by which the continents and their roots (to depths of 250 km) have been formed, modified or destroyed at different times throughout Earth's 4.6 billion year evolution.

The role of oceanic plateaus and mantle plumes in building protocontinents or modifying lithospheric volumes will be evaluated. The results will provide a more robust framework for interpreting the architecture of Earth's lithosphere and will have relevance to the formation and location of resources such as Ni, PGEs, Au and diamonds.Read moreRead less
Large-scale three dimensional deformation of the lithosphere by subduction and mantle flow. We will be modelling of the dynamics of the Earth's crust and shallow lithosphere in response to the huge stresses created by plate motions. For Australia these stresses are transmitted from the distant plate boundaries, but they have a direct controlling influence on the evolution of the petroleum rich basins of Australia.

We will be modelling of the dynamics of the Earth's crust and shallow lithosphere in response to the huge stresses created by plate motions. For Australia these stresses are transmitted from the distant plate boundaries, but they have a direct controlling influence on the evolution of the petroleum rich basins of Australia. These basins have reached maturity; further exploration will be in deep water where geophysical prospecting methods are unreliable. Model-driven "exploration geodynamics" methods such as those we are developing will be needed to support traditional exploration techniques in these areas.Read moreRead less

Double and triple dating are exciting new ANU-Yale breakthroughs that can be used to more accurately identify the source of sediment in rivers and sedimentary rocks than is possible using existing techniques. They have fundamental applications in the study of erosion, tracing the source of heavy minerals in titanium deposits and in determining the source of sedimentary sequences that host oil. Under favourable circumstances double dating can be used also to date sediments that are devoid of fossils, which has direct application in oil exploration.Read moreRead less
