Pyrogenic carbon is a poorly constrained, slow-cycling terrestrial carbon pool with significant carbon sequestration potential. The project expects to expand the newly developed hydrogen pyrolysis analytical capability to provide high throughput, robust measurement of the abundance and isotope composition of pyrogenic carbon in soils and sediments. This will provide significant benefit, such as the ability to make significant advances in areas as diverse as geochronology, archaeology, palaeoecology, soil science geomorphology and carbon cycle/sequestration science.Read moreRead less

A coupled high temperature elemental analyser - gas chromatograph - mass spectrometer for climate, water and ecological research: This project is for a high temperature, elemental analysis, gas chromatography, isotope mass spectrometry facility. This would permit the analysis of the isotopes of up to four elements in a range of environmental samples such as tree cellulose, ecological samples and dissolved nutrients in surface and ground waters. Results will help improve our understanding of climate - surface water - ground water interactions, ecosystem function, and past climate and environmental change. The new facility will meet the need for organic isotope analyses to better understand the underlying physical processes.Read moreRead less
High resolution timeframe for hominin evolution in the Turkana Basin, Kenya. This project aims to establish a high-resolution timeframe for hominin evolution in the famed Omo-Turkana Basin, Kenya. The Basin hosts a vast array of hominin fossils that cover more than four million years of human evolution, and interbedded volcanic deposits within the Basin sediments has provided much of our current constraints on the timing of hominin evolution. However critical knowledge gaps remain. Using new ins ....High resolution timeframe for hominin evolution in the Turkana Basin, Kenya. This project aims to establish a high-resolution timeframe for hominin evolution in the famed Omo-Turkana Basin, Kenya. The Basin hosts a vast array of hominin fossils that cover more than four million years of human evolution, and interbedded volcanic deposits within the Basin sediments has provided much of our current constraints on the timing of hominin evolution. However critical knowledge gaps remain. Using new instrumentation and dating methods, this project will provide an ultra-precise chronological framework for the basin. This is critical for transforming our understanding of hominin evolution and migration, under changing climatic and environmental conditions.Read moreRead less
Mantle evolution and the origin of Earth's atmosphere. This project aims to investigate Earth’s early evolution and the origin of our atmosphere. Using state-of-the-art instrumentation the project will measure noble gas and tungsten isotopes in unique volcanic glasses that record the composition of the Earth’s mantle. These measurements are expected to clarify the relationship between the formation of Earth’s atmosphere, mantle and core, and to generate new knowledge about convective currents ....Mantle evolution and the origin of Earth's atmosphere. This project aims to investigate Earth’s early evolution and the origin of our atmosphere. Using state-of-the-art instrumentation the project will measure noble gas and tungsten isotopes in unique volcanic glasses that record the composition of the Earth’s mantle. These measurements are expected to clarify the relationship between the formation of Earth’s atmosphere, mantle and core, and to generate new knowledge about convective currents in the modern mantle. The project aims to train the next generation of Earth scientists and to provide new knowledge to assist in overcoming the challenges in mitigating climate change and sustaining a resource-based economy.Read moreRead less
Global Scale Cycling of Noble Gases and Halogens. A novel approach for combined measurement of halogens and noble gases will be used to provide the first constraints on the concentrations of these elements in key reservoirs within subduction zones. The data will revolutionise our understanding of how noble gases and halogens transfer between the Earth's atmosphere and mantle, which has profound implications for our planet's origin and evolution. In addition, the study will provide practical info ....Global Scale Cycling of Noble Gases and Halogens.

The data will revolutionise our understanding of how noble gases and halogens transfer between the Earth's atmosphere and mantle, which has profound implications for our planet's origin and evolution. In addition, the study will provide practical information about how economically important hydrothermal ore deposits form on the seafloor and it will test models for orogenic gold mineralisation.

This joint Melbourne-Curtin facility seeks to generate ultra-precise age data from ever smaller and younger samples, such as minute particles from space return missions and tiny inclusions in diamonds. The facility is expected to revolutionise noble gas dating techniques, resulting in new knowledge on solar system genesis, hominid evolution, indigenous migrations, palaeo-climate change, natural hazards and ore deposit formation, while further enhancing Australia’s international leadership and competitive advantage in the discipline.

The plasma-source mass spectrometer will be dedicated to applying these techniques to earth surface processes, and establishing unique capabilities to decipher how soil and water resources respond to modern and past climate change in Australia.Read moreRead less
The recovery of seagrass beds: the role of catchments and options for management responses. Seagrass beds once dominated tidal flats but are disappearing at an increasing rate due to human actions, both in Australia and around the world. This project will develop an understanding of the processes that cause these losses, the factors that prevent seagrass-bed re-establishment, and provide a framework for evaluating alternative management options.
Identifying the secular evolution of chemical heterogeneity in the mantle as probed by deep mantle plumes. This project aims to focus on modes and timescales of melting associated with deep mantle plumes. These melts form massive magmatic bodies and volcanic flood basalt provinces throughout Earth’s history and record the secular chemical evolution of the Earth’s mantle. Selective igneous bodies contain high-grade noble metal deposits and coincide with global mass extinction linked to anoxic oce ....Identifying the secular evolution of chemical heterogeneity in the mantle as probed by deep mantle plumes. This project aims to focus on modes and timescales of melting associated with deep mantle plumes. These melts form massive magmatic bodies and volcanic flood basalt provinces throughout Earth’s history and record the secular chemical evolution of the Earth’s mantle. Selective igneous bodies contain high-grade noble metal deposits and coincide with global mass extinction linked to anoxic ocean events in response to atmospheric volcanic pollution. This project aims to provide knowledge of planetary surface evolution in response to mantle dynamics, place constraints on enrichment processes of metals in ore quality in plume-derived melts, and may help understandings of the relation between massive volcanic eruptions and climate variability.Read moreRead less

This project aims to reconcile the radically different views on the structure of the Earth’s mantle, based on geochemical (mostly noble gas) and geophysical data. This objective will be addressed through innovative noble gas analyses of well-characterised diamond samples, including gem-stones used for previous dating studies. In combination with carbon isotopic results, this information will be used to constrain the structure and temporal/spatial evolution of the Earth’s mantle. A related outcome will be an improved understanding of the mantle source regions of diamonds and diamond formation.Read moreRead less
