This project plans to use cutting-edge instrumentation to develop a novel method for dating geological materials formed in a critical time window for which no dating technique currently exists. The last million years of Earth’s history has seen dramatic changes in global climate and environment, with catastrophic volcanic eruptions and numerous other natural processes shaping landforms and ecosystems. A major challenge for studying these phenomena and their impacts is the dating of geological archives in the time window between 50 000 and 1 000 000 years. This project aims to develop a method for dating young volcanic rocks that can close this critical gap. The result would be a new dating tool with broad implications for the Quaternary sciences globally, including paleoclimate and paleoenvironmental reconstructions, natural hazards assessment, hominin evolution and archaeology.

该项目计划使用尖端仪器开发一种新的方法，用于测定在目前尚不存在测年技术的关键时间窗内形成的地质材料的年代。地球历史的最后一百万年见证了全球气候和环境的戏剧性变化，灾难性的火山喷发和许多其他自然过程塑造了地貌和生态系统。研究这些现象及其影响的一大挑战是对5万年至1000年之间的时间窗口中的地质档案进行年代测定。该项目旨在开发一种方法来测定年轻的火山岩的年龄，以缩小这一关键差距。其结果将是一种新的测年工具，对全球第四纪科学具有广泛的影响，包括古气候和古环境重建、自然灾害评估、人类进化和考古学。
