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.

短命的同位素226Ra为限制地球内部熔融和岩浆/流体运输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物质的沉积物的年龄。在麦格理大学安装高灵敏度热电离质谱计将使这些令人兴奋的努力的研究成为可能，并增强具有广泛和持久实用的世界级分析设施。计划中的研究将限制地球深处的过程、岩浆/水的运移过程、岩浆-地幔/层析、火山灾害、矿床形成、有争议的气候模型、土壤侵蚀和早期行星分化。
