Deep-sea coral ocean-climate records of the last glacial and recent eras. The project aims to predict the ocean carbon dioxide sink’s long-term capacity and future trajectories of global warming and increasing carbon dioxide. This project will use geochemical proxies encoded in the skeletons of deep-sea corals in the Perth Canyon, Tasman seas, and Antarctica, in the heart of the ocean-climate system, to reveal continuous long-term records of environmental change at annual-decadal resolution for ....Deep-sea coral ocean-climate records of the last glacial and recent eras. The project aims to predict the ocean carbon dioxide sink’s long-term capacity and future trajectories of global warming and increasing carbon dioxide. This project will use geochemical proxies encoded in the skeletons of deep-sea corals in the Perth Canyon, Tasman seas, and Antarctica, in the heart of the ocean-climate system, to reveal continuous long-term records of environmental change at annual-decadal resolution for our recent past (hundreds to thousands of years) and the Last Glacial Maximum. These records are expected to provide a more accurate understanding of Earth’s long-term responses to anthropogenic carbon dioxide emissions and global warming.Read moreRead less

A digital mineralogy and materials characterisation hub for petrology, mineralogy, exploration, metallurgy and reservoir characterisation research: This project will establish a digital mineralogy and materials characterisation hub for applications in petrology, geometallurgy, reservoir characterisation, environmental science, soil science, mineral processing and extractive metallurgy research. An automated mineral analysis instrument would complement the mineral separation (selFrag HV pulse fragmentation) and microanalytical facilities (SHRIMP/Cameca ion microprobes and ELA-ICP-MS) available to the participants via the John de Laeter Centre for Isotope Research. The instrument and software package making up the FEI QEMSCAN 650F model is the most advanced configuration on the market, and ideally suited for the high level research projects undertaken by the partner institutions.

ARC Centre of Excellence for Core to Crust Fluid Systems. Water is essential for human existence, indeed for life's beginning. The circulation of water between the surface and the deep interior lubricates the internal dynamics that keep Earth geologically alive; it is crucial to most Earth systems, including the evolution of the hydrospher/atmosphere/biosphere, and the development of giant ore deposits.

Water is essential for human existence, indeed for life's beginning. The circulation of water between the surface and the deep interior lubricates the internal dynamics that keep Earth geologically alive; it is crucial to most Earth systems, including the evolution of the hydrospher/atmosphere/biosphere, and the development of giant ore deposits. However, the origin, abundance, speciation and movements of fluids inside Earth are largely unknown, and represent key issues in modern geoscience. This CoE will integrate previously disparate fields - geology, tectonics, geochemistry, petrophysics, geophysics and dynamic modelling - to understand the workings of Earth's deep plumbing system.Read moreRead less
From Synchrotron Characterisation of Single Fluid Inclusions to Archaean Geodynamics: An Integrated Study of Fluid-Rock Interaction in the Primitive Crust. In the primitive Earth, a wide range of phenomena including the initiation of biological activity and the formation of ore deposits were related to the mobilisation of mineralised fluids through the crust. In the Archaean craton of the Pilbara (WA), we have identified, within its tectonic framework, a crustal-scale plumbing system that channe ....From Synchrotron Characterisation of Single Fluid Inclusions to Archaean Geodynamics: An Integrated Study of Fluid-Rock Interaction in the Primitive Crust. In the primitive Earth, a wide range of phenomena including the initiation of biological activity and the formation of ore deposits were related to the mobilisation of mineralised fluids through the crust. In the Archaean craton of the Pilbara (WA), we have identified, within its tectonic framework, a crustal-scale plumbing system that channelled large volumes of mineralised hydrothermal solutions. Our objective is to understand the development of this plumbing system in relation to Archaean crustal geodynamics using a combination of structural geology, metamorphic petrology, geochronology, geochemistry, and the analysis of single-fluid inclusion using synchrotron and other X-ray sources.Read moreRead less

Unlocking Rare Earth Elements from the Earth Crust. This project will explore the mechanisms controlling the mobility of Rare Earth Elements (REE) in natural and engineered hydrothermal systems. The project will generate essential geochemical and thermodynamic data of important REE host minerals, and thereby significantly improve our capacity to quantify the behaviour of REE during complex ore-forming and hydrometallurgical processes.

This project will explore the mechanisms controlling the mobility of Rare Earth Elements (REE) in natural and engineered hydrothermal systems. The project will generate essential geochemical and thermodynamic data of important REE host minerals, and thereby significantly improve our capacity to quantify the behaviour of REE during complex ore-forming and hydrometallurgical processes. The anticipated outcomes include: facilitate discovery of new REE deposits by improving understanding of their formation; and facilitate optimisation and development of innovative techniques for REE ore processing. This knowledge and expertise will help Australia to become a world leader in supplying REE for the transition to a carbon-neutral economy.Read moreRead less

An Equilibrium Inlet-Proton Transfer Reaction-Mass Spectrometer. Biogenic volatile organic compounds (BVOC) play a key role in earth system processes but little is known about the amount of BVOCs emitted, and the mechanisms underlying their production in marine habitats, despite these being potential hotspots for BVOC emissions. The aim of this proposal is to custom build a portable equilibrator inlet proton transfer reaction mass spectrometer for measurements of BVOC’s in coastal waters.

Biogenic volatile organic compounds (BVOC) play a key role in earth system processes but little is known about the amount of BVOCs emitted, and the mechanisms underlying their production in marine habitats, despite these being potential hotspots for BVOC emissions. The aim of this proposal is to custom build a portable equilibrator inlet proton transfer reaction mass spectrometer for measurements of BVOC’s in coastal waters. This will be the first such instrument in the southern hemisphere and it will enable us to make in situ, high-precision measurements which will lead to ground-breaking advances that will revolutionise our understanding of BVOC cycling in coastal environments and their influence on the global climate system.

Resolving the geochemistry of coastal floodplain blackwaters. Deoxygenated dead zones are a rapidly growing global crisis in coastal areas. A major cause of dead zones in our estuaries is the formation and release of blackwaters from coastal wetlands. This project will provide the knowledge necessary to manage blackwaters in these wetlands and to greatly improve the health and sustainability of our estuaries.
Geochemistry of ore metals at very high temperatures. The world’s largest copper and gold mines occur in extinct volcanoes around the Pacific Rim. Understanding how these essential metals are mobilised from magmas in the roots of volcanoes to become ore deposits and how to recognize where this has occurred is crucial in exploration for new deposits.
Constructing a temporally-constrained palaeoecological model of Quaternary faunal evolution and extinction in eastern Australia. Increased climatic variability and human-induced environmental degradation have had severe impacts on biodiversity, socio-economic sustainability and possibly our own future survival, thus attracting global attention.

Increased climatic variability and human-induced environmental degradation have had severe impacts on biodiversity, socio-economic sustainability and possibly our own future survival, thus attracting global attention. This study will help unravel the causes of the extinctions of Australia's large-size animals (megafauna) during the periods of last glaciation and earliest human colonisation of Australia. Investigating the causes of megafauna extinction is essential for an understanding of how those prehistoric events shaped the modern biota, and for the development of conservation strategies for our endemic faunas in an era of increased climatic and environmental variability and vulnerability.Read moreRead less
