『Abstract
　The absence of Ce anomaly and significant positive correlation between Ce and Fe in the weathering profiles and sedimentary carbonate rocks of the Baltic Shield with an age of 2.8-2.1 Ga indicate that Fe3+ was the main form of Fe migration in the Archean-Paleoproterozoic exogenous environments in the Baltic Shield. The Ce distribution was mainly controlled by hydrogen index rather than redox conditions.』
