The geochemistry of rare earth elements in carbonate melts. This project aims to determine why deposits of rare earth elements, which are critical for modern devices and technologies such as phones, tablets and plasma screens, are associated with carbonate magmas. The global supply of these critical metals is geopolitically unstable and, although Australia has significant reserves, there is very limited production. By improving our understanding of the geochemical behaviour of the rare earths th ....The geochemistry of rare earth elements in carbonate melts. This project aims to determine why deposits of rare earth elements, which are critical for modern devices and technologies such as phones, tablets and plasma screens, are associated with carbonate magmas. The global supply of these critical metals is geopolitically unstable and, although Australia has significant reserves, there is very limited production. By improving our understanding of the geochemical behaviour of the rare earths this project aims to develop new reverse-engineering methods for their extraction, which will improve the security of supply of these elements and enhance Australia's role in high-tech industries. The project will enhance the profitability of the Australian resources sector through improved extraction economics and will secure the supply of these critical metals for Australian high-tech industries and export. The outcomes will be targeted initially at junior resource companies that are not yet profitable.Read moreRead less

This project aims to investigate the earliest records of tropical forests occupied by modern humans. This project expects to reconstruct ancient tropical ecosystems through time and in unprecedented detail by applying interdisciplinary methods including analyses of fossil mammals, carbonates, and pollen records. Expected outcomes of this project include novel ecological techniques of reconstructing the tropical forests that people first inhabited, and advancing our understanding of modern human behaviour, environmental adaptation, and past exploitation of key ecosystems. This should provide significant benefits such as better understanding of the long-term interaction between tropical forests, their faunas, and people.Read moreRead less
Experimental and empirical insight into melting of the early Earth's mantle. The early Earth's mantle produced melt at much higher temperature than today, creating rocks with unique chemistries and mineralogies. But pressing knowledge gaps about hot mantle melting remain. The aim of this project is to generate new experimental and empirical knowledge to help closing these gaps by:
(i) conducting high pressure experiments to refine phase-composition relationships and element partitioning;
(ii) qu ....Experimental and empirical insight into melting of the early Earth's mantle. The early Earth's mantle produced melt at much higher temperature than today, creating rocks with unique chemistries and mineralogies. But pressing knowledge gaps about hot mantle melting remain. The aim of this project is to generate new experimental and empirical knowledge to help closing these gaps by:
(i) conducting high pressure experiments to refine phase-composition relationships and element partitioning;
(ii) quantifying mineral fabrics in cratonic peridotites to understand the movement of early continents; and
(iii) constructing the first petrological deep time model for greenstone belt volcanic rocks.
The expected outcomes are better models for the early Earth's melting and tectonic regimes and insight into the emergence of land.Read moreRead less
The mighty ape’s last stand. This project aims to study the fate of primates in southern Asia, where evidence for megafaunal extinction is rare. Why Gigantopithecus blacki, the largest ever primate, disappeared is unknown, while humans in the region survived. This project will model dating techniques across sites to identify a precise extinction window and compare behaviour and past environmental conditions to determine why the ape failed and man persevered. Outcomes will generate a new understa ....The mighty ape’s last stand. This project aims to study the fate of primates in southern Asia, where evidence for megafaunal extinction is rare. Why Gigantopithecus blacki, the largest ever primate, disappeared is unknown, while humans in the region survived. This project will model dating techniques across sites to identify a precise extinction window and compare behaviour and past environmental conditions to determine why the ape failed and man persevered. Outcomes will generate a new understanding of past environmental change as a driver of megafaunal extinction in comparison with human adaption and survival.Read moreRead less
Role of water in earth and planetary evolution. This project aims to understand the role of water in the building of our solar system, Mars and Earth. Surprisingly little is known about key issues surrounding the origin of water and its subsequent recycling on Earth. This project will use new techniques for measuring low abundances of water along with oxygen isotopes, to measure water abundances and oxygen isotopes in meteorites and terrestrial rocks to establish how water was delivered to Earth ....Role of water in earth and planetary evolution. This project aims to understand the role of water in the building of our solar system, Mars and Earth. Surprisingly little is known about key issues surrounding the origin of water and its subsequent recycling on Earth. This project will use new techniques for measuring low abundances of water along with oxygen isotopes, to measure water abundances and oxygen isotopes in meteorites and terrestrial rocks to establish how water was delivered to Earth and to understand how water is geologically recycled. This is expected to have direct bearing on where and how Earth's water originated, how water is retained in mantle and crustal minerals and it will have broad implications for understanding volcanic hazards and formation of ore deposits. This will lead to a new capability for combined water and oxygen isotope analysis in Australian geoscience leading to technological development and commercialisation of instrumentation.Read moreRead less

This project aims to investigate the world’s oldest faunal succession in the fossil record by determining the presence and extent of a sedimentary gap and confirming the role of time in the control of fossil distribution. Significant breakthroughs and capacity building are expected in the areas of palaeontology, evolutionary biology and geology using a hitherto unrecognised hiatus in the rock succession. Project outcomes include enhanced understanding of the first animal communities on Earth – these should provide significant benefits, such as revealing Australia's unique record of oldest complex organisms, while bringing additional tourism to the region, and increasing the strength of the Flinders Ranges UNESCO World Heritage nomination.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.
