Chronostratigraphic, molecular and isotopic approaches to age petroleum. The project aims to reduce the costs of drilling in deep-water offshore by better identifying potential drilling sites. The North-West shelf offshore Australia is the main supplier of liquefied natural gas. However, there is uncertainty about the age of petroleum (oil and gas) discovered in the region. It is not currently possible to constrain an age of fluids to a number of source rocks. The aims are to develop a high-leve ....Chronostratigraphic, molecular and isotopic approaches to age petroleum. The project aims to reduce the costs of drilling in deep-water offshore by better identifying potential drilling sites. The North-West shelf offshore Australia is the main supplier of liquefied natural gas. However, there is uncertainty about the age of petroleum (oil and gas) discovered in the region. It is not currently possible to constrain an age of fluids to a number of source rocks. The aims are to develop a high-level age discriminative tool for fluids. An interdisciplinary approach will be applied using state-of-the-art techniques including comprehensive two dimensional gas chromatography time-of-flight mass spectrometry, compound specific isotope analysis of hydrocarbons, clumped isotopes of methane and metagenomics.Read moreRead less

Summary
A modern, high-tech mineral separation facility for geochemistry and isotope science. This project will support geoscience research in Western Australia that incorporates a new conservative way of fragmenting rocks to their constituent grains. The facility will provide mineral samples for discovery science and for applied research for the minerals and petroleum industries.

Summary
Unravelling the transformation pathways and fate of dissolved organic carbon and nitrogen in shallow coastal sediments. This project will significantly advance our understanding of the cycling of dissolved organic carbon and dissolved organic nitrogen in shallow coastal sediments, a potentially major part of global carbon and nitrogen cycles. This will have direct implications for the management and protection of Australian coastal systems and the world's oceans.

Summary
A high precision, automated system for studying greenhouse gas cycling in coastal environments. This facility will perform automated, long-term greenhouse gas measurements in coastal waters. The expected outcome of research at this facility is a better understanding of how the coastal ocean acts as a source or sink of carbon dioxide, nitrous oxide, methane, and volatile organic carbon.
Sulfur Cycling in Toxic Oozes, Microbialites and Petroleum. This project will apply compound specific sulfur isotope analyses to sulfur-rich deposits from extreme environments including sulfidic black oozes (Peel-Harvey estuary); modern microbialites (for example, Shark Bay) and oils/source rocks (established and frontier oil fields). Sulfur isotopic data, integrated with other stable isotopic and molecular data, will greatly assist the study of sulfur biogeochemical cycles and mechanisms of org ....Sulfur Cycling in Toxic Oozes, Microbialites and Petroleum. This project will apply compound specific sulfur isotope analyses to sulfur-rich deposits from extreme environments including sulfidic black oozes (Peel-Harvey estuary); modern microbialites (for example, Shark Bay) and oils/source rocks (established and frontier oil fields). Sulfur isotopic data, integrated with other stable isotopic and molecular data, will greatly assist the study of sulfur biogeochemical cycles and mechanisms of organic sulfurisation at different diagenetic stages or geological ages. The project aims to address national concerns through measuring the respective impact of anthropogenic and natural changes on environments, helping to understand the evolution of life on Earth and contributing to efficient discovery of our natural petroleum systems.Read moreRead less
Palaeoclimate reconstructions from the isotopic signatures of fossilised leaf waxes. This project develops a method for using the chemical signature of fossilised leaf waxes to reconstruct hydrologic change in south-eastern Australia during the Holocene (last 10,000 years) and Eocene (56-34 million years ago). Understanding climate in the geologic past is essential for testing models and projecting future climate with rising carbon dioxide.

Summary
Resolving the role of aquatic systems in processing terrestrial carbon. The aquatic and terrestrial carbon cycles are intrinsically linked with changes in terrestrial carbon dynamics altering the aquatic carbon cycle. However, the main methodology employed to assess land-atmosphere carbon dioxide fluxes fails to account for carbon losses through subsurface lateral exports of carbon via groundwater. This project aims to resolve the importance and drivers of this pathway, along with the ultimate f ....Resolving the role of aquatic systems in processing terrestrial carbon. The aquatic and terrestrial carbon cycles are intrinsically linked with changes in terrestrial carbon dynamics altering the aquatic carbon cycle. However, the main methodology employed to assess land-atmosphere carbon dioxide fluxes fails to account for carbon losses through subsurface lateral exports of carbon via groundwater. This project aims to resolve the importance and drivers of this pathway, along with the ultimate fate of the carbon once it reaches the aquatic environment. This project aims to contribute to closing a significant gap in our understanding of terrestrial-aquatic carbon cycling and will quantify a potentially important yet poorly understood component of regional and global carbon budgets.Read moreRead less
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.
Advancing Mineral Exploration Models for Orogenic Gold Deposits. This interdisciplinary project links geochemistry with crustal-scale fluid migration, aiming to improve mineral exploration success for orogenic gold deposits. In doing so, it intends to provide a more holistic view of gold deposit genesis. This project plans to focus on the Victorian goldfields, which have world-class historic gold production, an existing seismic transect, and a geologic setting that will address key problems in g ....Advancing Mineral Exploration Models for Orogenic Gold Deposits.

In doing so, it intends to provide a more holistic view of gold deposit genesis. This project plans to focus on the Victorian goldfields, which have world-class historic gold production, an existing seismic transect, and a geologic setting that will address key problems in gold deposit genesis. A series of modelling techniques will be used to marry structural and geochemical aspects of gold deposit formation at a scale that has not been previously attempted.Read moreRead less
