A new rheological model for Australia to improve seismic hazard estimates and study the region's recent tectonic history and landform evolution. Australia is currently being squeezed between three active mountain belts, the Himalayas, the Papua New Guinea Highlands and the Southern Alps in New Zealand.

Australia is currently being squeezed between three active mountain belts, the Himalayas, the Papua New Guinea Highlands and the Southern Alps in New Zealand. We propose to integrate a large number of geological and geophysical databases that have been collected over the past few decades to develop a three-dimensional rheological model of the Australian continent, that is a model that predicts where and how Australia is deforming today. Combined with new, targeted field work, this model will be used to predict where earthquakes are likely to take place but also to study how our old continent is affected by these active mountain belts to create the present-day landscapes in which we live.Read moreRead less
Lifting the veil on the Geological Dark Ages: The search for Hadean Crust on Earth. The project involves detailed field and isotopic study of some of the oldest known rocks and minerals to develop the first comprehensive picture of the earliest growth of the Australian continent. The data will reveal the timing and processes of continent formation and shed new light on the enigmatic early period of the Earth's evolution.
From organo-mineral nanocomposite to Australian basins; an integrated approach to unconventional gas exploration and development. Gas production from unconventional shale reservoirs is a potential major energy boom in Australia that will lower carbon emissions over comparable coal and oil use. The geological controls of shale are currently too poorly understood to direct effective exploration. This project will be the largest international effort to develop this knowledge.

Accurate timekeeping is central to the environmental and archaeological sciences. Radiocarbon dating is the leading geochronological technique for events of the past 50,000 years, but the issue for sample contamination remains a major source of concern. Avoidance of contaminants can be achieved through the identification of specific biomolecular compounds that unambiguously formed part of the original sample, and the isolation of these biomolecules for radiocarbon dating using accelerator mass spectrometry. Here we request funds to establish Australia's first compound-specific radiocarbon dating facility, to obtain ages of high accuracy for key studies of climate and landscape change, evolutionary biology and archaeology.Read moreRead less

SPIDE2R will be a new generation mass spectrometer for very precise and sensitive dating and forensics applications in earth and planetary sciences, hydrology, climate studies, and nuclear and archaeological fingerprinting. The unprecedented sensitivity of this unique instrument will provide enhanced capabilities for solving long-standing problems requiring precise geological time resolution, as well as opening new areas of research. It will be the instrument of choice for analysing small, rare samples such as those returned by space missions. The Australian-built high sensitivity source and ion detection systems can be retrofitted onto other mass spectrometers, opening a new area of commercialisation.Read moreRead less

Summary
A global fireball observatory. This project aims to expand the Desert Fireball Network (DFN) and build a Global Fireball Observatory. Nearly everything known about the origin and evolution of the solar system comes from analysis of meteorite falls, but scientists have almost no constraint on where they come from. This project will address this constraint by tracking hundreds of meteorite falls, and pinpointing each one’s origin in the solar system. Benefits include capitalising on the innovation ....A global fireball observatory. This project aims to expand the Desert Fireball Network (DFN) and build a Global Fireball Observatory. Nearly everything known about the origin and evolution of the solar system comes from analysis of meteorite falls, but scientists have almost no constraint on where they come from. This project will address this constraint by tracking hundreds of meteorite falls, and pinpointing each one’s origin in the solar system. Benefits include capitalising on the innovations and technologies that underpinned the DFN, and leveraging a NASA partnership for administrative support and advanced instrumentation development. Tracking for space situational awareness is also expected to benefit Australian national security.Read moreRead less

Summary
A regional optical dating facility in Australia. This project aims to establish an open access, end-user friendly optical dating facility in Australia. This will address shortcomings in the capacity and geographical coverage of the existing national geochronology infrastructure and enable Australian researchers to reconstruct past records of climate change, human evolution, ecological vulnerabilities, natural and man-made hazards and environmental disturbance over historical to near-million-year ....A regional optical dating facility in Australia.

This will address shortcomings in the capacity and geographical coverage of the existing national geochronology infrastructure and enable Australian researchers to reconstruct past records of climate change, human evolution, ecological vulnerabilities, natural and man-made hazards and environmental disturbance over historical to near-million-year timeframes. This project is expected to increase commercial demand for geoscience services and lead to better understanding of Australia’s natural heritage and its long-term vulnerabilities.Read moreRead less

This year sees the highly anticipated return of the Hayabusa2 spacecraft to Woomera carrying samples of the asteroid Ryugu. This is only the fifth extraterrestrial sample return mission in history. The research team has been invited to participate in the preliminary examination which will take place in Japan in early 2021. The investigators have developed unique analytical skills that allow measurement of small amounts of rock for oxygen isotope compositions at unprecedented precision. This project aims to characterise a suite of carbonaceous chondrites, which appear to be the best match to Ryugu, and therefore will provide the exemplar data to understand the provenance of Ryugu, and place it in the context of solar system materials.

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
