英文摘要
In this project we aim to further our understanding of the evolution of oxygen levels and ocean chemistry throughout the Paleoproterozoic, assess different modes of precipitation for iron formations and evaluate a changing environment for the evolution of complex life. We will investigate a unique set of iron formations from Western Australia, spanning a time from 2.42 Ga to 1.86 Ga across and beyond the Great Oxidation Event, for their redox potential. For this, we will combine field observations and petrography with state-of-the-art major and trace element measurements (including REE+Y analyses), and stable Mo- and Fe-isotope data.
