The proposed research is focused on geochronology - the science of determining absolute geological time using radioactive decay. It will develop, test and apply the 187Re-187Os radioactive decay scheme to date sulfide minerals that form in economically-important ore deposits of copper, lead and zinc from Canada and other locations internationally. The research has the potential to develop tools that will revolutionize our understanding of when these ores form, and thereby better identify how these ores form – to identify the causative geological processes and events that formed ore.

拟议中的研究重点是地质年代学，即利用放射性衰变确定绝对地质年代的科学。它将开发、测试和应用187Re-187Os放射性衰变方案，以确定在加拿大和其他国家具有重要经济意义的铜、铅和锌矿床中形成的硫化物矿物的年代。这项研究有可能开发出工具，彻底改变我们对这些矿石何时形成的理解，从而更好地确定这些矿石是如何形成的，从而确定形成矿石的原因地质过程和事件。
