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.

该项目旨在通过使用创新的地球化学替代物，研究海洋化学在“无聊的十亿年”（18亿至8亿年前）真核生物进化中的作用，以及沉积岩如何记录过去的海洋化学。该项目预计将利用跨学科方法产生地球化学、沉积学和古生物学方面的新知识。预期成果包括从数量上了解沉积岩的形成，以及演变与海洋养分和金属丰度之间的联系。这应该会带来重大的好处，比如了解含矿沉积岩的形成和变化，以及地球中世纪期间生命是如何进化的。
