A ThermoFinnigan Triton high-sensitivity thermal ionisation mass spectrometer for constraining geoscience rates and environmental processes via Ra and Os analysis

短寿命同位素226 Ra为限制地球内部的熔融和岩浆/流体输送过程的性质提供了一个强大的新工具。相反，Os同位素可以追踪古老的再循环组分，核幔边界相互作用和富含有机质的沉积物的年代。在麦考瑞大学安装高灵敏度热电离质谱仪将使这些令人兴奋的研究工作成为可能，并提高世界一流的分析设施的广泛和持久的效用。计划中的研究将限制地球深部过程、岩浆/水的输送过程、岩浆-地幔/层析、火山灾害、矿石存款形成、有争议的气候模型、土壤侵蚀和早期行星分化。

The short-lived isotope 226Ra provides a powerful new tool for constraining the nature of melting and magma/fluid transport processes within the Earth. Conversely, Os isotopes can track ancient recycled components, core-mantle boundary interaction and date organic-rich sediments. The installation of a high-sensitivity thermal ionisation mass spectrometer at Macquarie University will enable research in these exciting endeavours and enhance a world-class analytical facility with widespread and lasting utility. Planned research will constrain deep earth processes, magma/water transport processes, magma-mantle/chromatography, volcanic hazards, ore deposit formation, controversial climatic models, soil erosion and early planet differentiation.
