Oxygenation history of the Earth and the evolution of complex life. This project will investigate how and when the atmosphere became oxygen-rich by analyzing ancient barrier reefs and other rocks that formed between 1000 to 300 million years ago, spanning the appearance and diversification of animals and plants. The project is significant because the buildup of oxygen in the atmosphere was arguably the most important chemical process ever to have occurred on Earth and controlled the evolution of ....Oxygenation history of the Earth and the evolution of complex life. This project will investigate how and when the atmosphere became oxygen-rich by analyzing ancient barrier reefs and other rocks that formed between 1000 to 300 million years ago, spanning the appearance and diversification of animals and plants. The project is significant because the buildup of oxygen in the atmosphere was arguably the most important chemical process ever to have occurred on Earth and controlled the evolution of environments, climate and life. A major outcome will be an improved understanding of how the Earth's atmosphere and climate are regulated by geological processes. This project will generate new knowledge about how sedimentary zinc, lead and copper ore deposits form, which may guide exploration for these commodities.Read moreRead less

Summary
The oxygenation of Earth’s early marine ecosystems. This project aims to map out the complex evolution of the Earth’s ocean ecosystems and oxygenation using marine carbonates. The oxygenation of Earth’s surface is one of the most profound processes to shape the planet, affecting all biological and geological systems. However, uncertainties remain in the timing of oxygenation and how it relates to the evolution of life. This project will develop our understanding of how Earth has remained habitab ....The oxygenation of Earth’s early marine ecosystems. This project aims to map out the complex evolution of the Earth’s ocean ecosystems and oxygenation using marine carbonates. The oxygenation of Earth’s surface is one of the most profound processes to shape the planet, affecting all biological and geological systems. However, uncertainties remain in the timing of oxygenation and how it relates to the evolution of life. This project will develop our understanding of how Earth has remained habitable through significant intervals of environmental change. Using the geology of Australia, and elsewhere, this project is expected to derive the oxygenation evolution of ancient seawater and its effect on reef ecosystems during critical intervals of Earth’s history.Read moreRead less
New Stratigraphy and Geostatistics for Gas and Water Resources . Management of gas and water resources is of significant importance to the Australian economy and society. Industry and government use digital modelling to assist in resources management. The first step in modelling is to correlate geological data and then use geostatistics to estimate properties in areas without data. This project aims to produce a new geological framework for the Surat Basin underpinned by new zircon ages and ages ....New Stratigraphy and Geostatistics for Gas and Water Resources . Management of gas and water resources is of significant importance to the Australian economy and society. Industry and government use digital modelling to assist in resources management. The first step in modelling is to correlate geological data and then use geostatistics to estimate properties in areas without data. This project aims to produce a new geological framework for the Surat Basin underpinned by new zircon ages and ages of fossils in sediments and a new geostatistical methodology to better represent flow properties in coal seams and aquifers. This is expected result in a more accurate modelling methodology that can be used by industry and government for modelling resources, including in other basins in Australia and worldwide.Read moreRead less
Evolution of Proterozoic multistage rift basins – key to mineral systems. This project will deliver a new quantitative and integrated exploratory framework for the mineral industry in Australia’s frontier sedimentary basins by integrating the latest advances in laboratory experimental tectonics with thermo-mechanical numerical, surface process and geophysical modelling. The project will use northern Australian basins as a natural laboratory to address the fundamental processes involved in the de ....Evolution of Proterozoic multistage rift basins – key to mineral systems. This project will deliver a new quantitative and integrated exploratory framework for the mineral industry in Australia’s frontier sedimentary basins by integrating the latest advances in laboratory experimental tectonics with thermo-mechanical numerical, surface process and geophysical modelling. The project will use northern Australian basins as a natural laboratory to address the fundamental processes involved in the development of sedimentary ore systems. The project will investigate how they can be detected by modern exploration techniques using a multidisciplinary approach with a team of experts with backgrounds in mineral and petroleum systems.

Reconstructing the Beetaloo/Greater McArthur Basin System . This project aims to build a stratigraphic and water chemistry framework for the greater McArthur Basin—a rock system that covers northern Australia from WA to Queensland. This will be a vital resource for researchers and energy/mineral explorers. This project expects to develop novel sediment dating and isotopic proxies for salinity, redox and bioproductivity and use them to build a sequence stratigraphic framework of the basin. The ex ....Reconstructing the Beetaloo/Greater McArthur Basin System . This project aims to build a stratigraphic and water chemistry framework for the greater McArthur Basin—a rock system that covers northern Australia from WA to Queensland. This will be a vital resource for researchers and energy/mineral explorers. This project expects to develop novel sediment dating and isotopic proxies for salinity, redox and bioproductivity and use them to build a sequence stratigraphic framework of the basin. The expected outcome is a unique 3D lithological, geochronological and geochemical framework for the basin. Expected benefits include de-risked information for the petroleum and minerals industry, assisting northern Australia's resources economy, as well as insights into the development of our planet in deep time.Read moreRead less

Summary
All you can eat: evolution of feeding in the largest animals on Earth. This project aims to establish how Baleen whales, the largest animals on Earth and major ecosystem engineers, evolved their signature filter-feeding strategy. Unlike other mammals, whales are toothless, and instead use a keratinous, comb-like sieve to filter vast amounts of small prey from seawater. Various approaches, including biomechanics, three-dimensional imaging, geochemistry and quantitative palaeobiology will unravel ....All you can eat: evolution of feeding in the largest animals on Earth. This project aims to establish how Baleen whales, the largest animals on Earth and major ecosystem engineers, evolved their signature filter-feeding strategy. Unlike other mammals, whales are toothless, and instead use a keratinous, comb-like sieve to filter vast amounts of small prey from seawater. Various approaches, including biomechanics, three-dimensional imaging, geochemistry and quantitative palaeobiology will unravel how and when filter feeding emerged, how it diversified over time, and whether its evolution correlated with past environmental change. The project is expected to reveal clues on how whales became one of the greatest ecological actors in the sea, and will benefit conservation by providing a glimpse into their future.Read moreRead less
