Summary
A New Generation Noble Gas Mass Spectrometer Facility for Advanced Research in the Earth, Planetary and Environmental Sciences. The current proposal, to establish a new Noble Gas Analytical Consortium for noble gas chronological and geochemical analyses, will generate new knowledge on the evolution of the Earth, with profound implications for past climate change, landscape evolution, formation of ore bodies, and terrestrial geodynamics. Consequently, the facility will conform to the National Res ....A New Generation Noble Gas Mass Spectrometer Facility for Advanced Research in the Earth, Planetary and Environmental Sciences. The current proposal, to establish a new Noble Gas Analytical Consortium for noble gas chronological and geochemical analyses, will generate new knowledge on the evolution of the Earth, with profound implications for past climate change, landscape evolution, formation of ore bodies, and terrestrial geodynamics. Consequently, the facility will conform to the National Research Priority of 'An Environmentally Sustainable Australia'. The new facility will ensure that Australian research remains at the forefront of international science development and will also provide essential training for the next generation of Australian scientists.Read moreRead less
What controls trace element levels in ore sulfides? A laser-ICPMS perspective. Sub-surface hydrothermal gold and base metal orebodies are surrounded by aprons of elevated metal concentrations, mainly within micro-sulfides, which is one sign mineral explorers use to widen their target. Here we test whether the hostrock contributes metal in the most distant parts of such halos, and if so, what factors control where hostrock metal begins to be detectable in a given system. We will make better model ....What controls trace element levels in ore sulfides? A laser-ICPMS perspective. Sub-surface hydrothermal gold and base metal orebodies are surrounded by aprons of elevated metal concentrations, mainly within micro-sulfides, which is one sign mineral explorers use to widen their target. Here we test whether the hostrock contributes metal in the most distant parts of such halos, and if so, what factors control where hostrock metal begins to be detectable in a given system. We will make better models of how metalliferous waters react with rock, potentially translating into million dollar savings through more efficient exploration. The ultrafine sampling and precision analyses required for this are possible because of an ARC-funded core program at CODES.Read moreRead less
