This project aims to use fossil micrometeorites to provide fundamental new data on changes in the chemistry of the ancient Earth's upper atmosphere before, during and after the Great Oxidation Event, the most significant atmospheric change in Earth’s history. This would provide insights into variations in the extent of interaction between the upper and lower atmosphere across the Great Oxidation Event. The project will also use these micrometeorites to investigate how the flux, composition and sources of extra-terrestrial material arriving on Earth changed over time.

该项目旨在利用微陨石化石提供关于地球历史上最重大的大气变化-大氧化事件之前、期间和之后古代地球高层大气化学变化的基本新数据。这将为深入了解大氧化事件中高层和低层大气之间相互作用程度的变化提供帮助。该项目还将利用这些微陨石来研究抵达地球的外星物质的通量、成分和来源如何随时间变化。
