High sensitivity and precision mass spectrometry for tracing Australia’s ancient evolution and securing our future groundwater resources: Micro-sampling thermal ionisation mass spectrometry (TIMS) provides the ability to undertake ultra low-level isotope analysis of earth and environmental samples. Analysis of radiogenic (for example, Neodymium, Strontium and Lead) and stable (for example, Boron) isotopes allows researchers to trace the evolution of the Australian continent from its beginnings in the Precambrian through to the impacts of climate change in the Quaternary period (the last 2.6 million years). The proposed micro-sampling TIMS facility will give researchers the opportunity to characterise mineral deposit formation, paleoclimate records and groundwater sources with new levels of accuracy and precision. This will help secure the economic and environmental future of Australia.

高灵敏度和高精度质谱法用于追踪澳大利亚古代演化和保护我们未来的地下水资源：微采样热电离质谱法（TIMS）提供了对地球和环境样品进行超低同位素分析的能力。对放射性成因（例如钕、锶和铅）和稳定同位素（例如硼）的分析，使研究人员能够追溯澳大利亚大陆从前寒武纪开始到第四纪（过去260万年）气候变化影响的演变过程。拟议的微型采样TIMS设施将使研究人员有机会以新的精度和精度描述矿床形成、古气候记录和地下水来源。这将有助于确保澳大利亚未来的经济和环境。
