Short summary
This study investigates the climatic mechanism that controlled the deposition of organic matter in the South Atlantic Cape Basin during the Early Cretaceous. The presented geochemical and climate modeling data suggest that fluctuations in riverine nutrient supply were the main driver of organic carbon burial on timescales < 1 Myr. Our results have implications for the understanding of Cretaceous atmospheric circulation patterns and climate-land-ocean interactions in emerging ocean basins.
