Summary
Mass spectrometry for next generation isotope analysis of silicate minerals. This project aims to establish a facility for mass spectrometry and sample preparation to enhance Australian capacity to analyse the stable isotope composition of silicate minerals. The project seeks to implement innovations that will greatly enhance the use of stable isotopes in silicate minerals by increasing analytical throughput and reducing cost. This will provide better understanding of the trajectories of environ ....Mass spectrometry for next generation isotope analysis of silicate minerals. This project aims to establish a facility for mass spectrometry and sample preparation to enhance Australian capacity to analyse the stable isotope composition of silicate minerals. The project seeks to implement innovations that will greatly enhance the use of stable isotopes in silicate minerals by increasing analytical throughput and reducing cost. This will provide better understanding of the trajectories of environmental change, formation of mineral deposits and identifying trade networks in prehistoric societies.Read moreRead less
The application of clumped isotope thermometry to the terrestrial environment. Clumped-isotope geochemistry, a novel method for measuring the temperature of formation of carbonate minerals, will be applied to terrestrial materials (soil carbonates, lake deposits and speleothems) from Australia and New Zealand. The method relates the abundance or 'clumping' of rare isotopes (for example, carbon dioxide of mass 47 as carbon-13, oxygen-18, oxygen-16) extracted from carbonates to their formation tem ....The application of clumped isotope thermometry to the terrestrial environment. Clumped-isotope geochemistry, a novel method for measuring the temperature of formation of carbonate minerals, will be applied to terrestrial materials (soil carbonates, lake deposits and speleothems) from Australia and New Zealand. The method relates the abundance or 'clumping' of rare isotopes (for example, carbon dioxide of mass 47 as carbon-13, oxygen-18, oxygen-16) extracted from carbonates to their formation temperature and is independent of the oxygen-18:oxygen-16 value of the host water from which the mineral precipitated. The materials to be investigated span the Last Glacial-Interglacial Transition and will provide robust past temperature estimates and the delta-oxygen-18 values of waters, thereby permitting hydrological balances (for example, precipitation/evaporation) to be constructed.

Summary
New frontier in Geoscience: A tandem trace element and isotopes facility. The project aims to integrate a multicollector mass spectrometer with the existing laser ablation laboratory at Southern Cross University to establish a unique facility offering tandem trace element and isotopes analysis. This will provide new methodological advancement by expanding the analytical range and obtaining information otherwise inaccessible to stand-alone instruments using traditional standardisation methods.

The project aims to integrate a multicollector mass spectrometer with the existing laser ablation laboratory at Southern Cross University to establish a unique facility offering tandem trace element and isotopes analysis. This will provide new methodological advancement by expanding the analytical range and obtaining information otherwise inaccessible to stand-alone instruments using traditional standardisation methods. Specifically, the integration of an innovative split stream system allows precise matching of elemental concentration with isotopic ratios, crucial for microscale resolution and data accuracy. The new infrastructure will confirm Australia’s leadership role and maintain its competitive advantage in geosciences.Read moreRead less
