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.

这是一个先进的设施，包含下一代多收集器质谱仪和超净气体管道系统，能够对地球、行星和考古材料进行超精确测年。这个墨尔本-科廷联合设施旨在从更小和更年轻的样本中生成超精确的年龄数据，例如来自太空返回任务的微小颗粒和钻石中的微小内含物。该设施预计将彻底改变惰性气体测年技术，从而产生关于太阳系起源、原始人类演化、土著迁移、古气候变化、自然灾害和矿石存款形成的新知识，同时进一步加强澳大利亚在该学科的国际领导地位和竞争优势。
