This project aims to investigate the role of ocean chemistry on the evolution of eukaryotes during the “Boring Billion” (1800-800 million years ago) and how sedimentary rocks record past ocean chemistry, by using innovative geochemical proxies. This project expects to generate new knowledge in geochemistry, sedimentology and paaleo-biology using interdisciplinary approaches. Expected outcomes include a quantitative understanding of the formation of sedimentary rocks, and of the links between evolution and marine nutrient and metal abundance. This should provide significant benefits, such as understanding the formation and alteration of ore-bearing sedimentary rocks and how life has evolved during Earth's Middle Age.

该项目旨在调查海洋化学对真核生物在“十亿”（1800-80万年前）中的作用，以及使用创新的地球化学代理，如何通过使用创新的海洋化学岩石来记录海洋化学的作用。该项目预计将使用跨学科方法来产生地球化学，沉积学和Paaleo生物学的新知识。预期的结果包括对沉积岩石形成的定量理解，以及进化与海洋养分与金属丰度之间的联系。这应该提供重大的好处，例如了解含矿石沉积岩石的形成和改变，以及在地球中年的生命如何发展。
