An advanced facility incorporating next generation, multi-collector mass spectrometer and ultra-clean gas line systems, capable of ultra-precise dating of Earth, planetary and archaeological material. This joint Melbourne-Curtin facility seeks to generate ultra-precise age data from ever smaller and younger samples, such as minute particles from space return missions and tiny inclusions in diamonds. The facility is expected to revolutionise noble gas dating techniques, resulting in new knowledge on solar system genesis, hominid evolution, indigenous migrations, palaeo-climate change, natural hazards and ore deposit formation, while further enhancing Australia’s international leadership and competitive advantage in the discipline.

一个先进的设施，结合了下一代，多收集器质谱仪和超清洁气体线系统，能够超精确地测定地球，行星和考古材料的年代。这个墨尔本和科廷的联合机构试图从更小、更年轻的样本中获得超精确的年龄数据，比如从太空返回任务中获得的微小颗粒和钻石中的微小内含物。预计该设施将彻底改变稀有气体定年技术，从而获得关于太阳系成因、人类进化、土著迁移、古气候变化、自然灾害和矿床形成的新知识，同时进一步提高澳大利亚在该学科的国际领导地位和竞争优势。
