Middle Age Earth: ocean chemistry and evolution in the Boring Billion

点击翻译按钮获取中文摘要

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.
