Lacustrine carbon sink: A hidden driver of the Late Cretaceous Cooling Event Lacustrine systems since the Mesozoic have sequestered large quantities of organic carbon, which may have important value for global climate cooling, …

During the #OAE2, volcanic activity decreased & #OrganicCarbon sequestration increased
Continental shelf & #deep-sea basins were major OC sinks. Organic-poor sediments, especially the Cretaceous Oceanic Red Beds (CORBs) suggests that post-OAE2 #CarbonSequestration was oxidized out of the seafloor 🪨🌊
