Isotopic dating of rocks and minerals has revolutionized the way we view our planet, and allowed us to attach an absolute timescale to a range of Earth processes from the evolution of life to formation of mineral deposits. Australian technology has long been at the forefront of this field, but it is apparent that our ability to date Earth materials has overtaken our ability to interpret these ages in terms of geologic processes. The results of this study and the associated collaboration will ensure that Australian understanding of what isotopic ages mean keeps pace with our ability to measure them. This will allow us to resolve finer details of Earth history, and improve our understanding of the planet and how best to manage it.

岩石和矿物的同位素测年彻底改变了我们看待地球的方式，并使我们能够为从生命进化到矿床形成的一系列地球过程提供绝对时间尺度。澳大利亚的技术长期以来一直处于这一领域的最前沿，但很明显，我们对地球物质的测年能力已经超过了我们从地质过程的角度解释这些年龄的能力。这项研究的结果和相关的合作将确保澳大利亚对同位素年龄的理解与我们测量同位素年龄的能力保持同步。 这将使我们能够解决地球历史的细节，并提高我们对地球的理解以及如何最好地管理它。
