Potential temporal and causal connections among various geologic events have long been discussed in the geological literature. More recently, signs of common periodicities in these …
The cause of the end-Cretaceous mass extinction is vigorously debated, owing to the occurrence of a very large bolide impact and flood basalt volcanism near the boundary …
From the latest Cretaceous (late Campanian to Maastrichtian,~ 75–66 Ma) to the earliest Paleogene, fluctuations in greenhouse climate, inferred primarily from marine sediments …
As an important contributor to the habitability of our planet, the oxygen cycle is interconnected with the emergence and evolution of complex life and is also the basis to …
Prolonged periods of low light and cold temperatures at Earth's surface are hypothesized effects of the end‐Cretaceous asteroid impact. However, debate remains about the causes …
Abstract The Cretaceous-Paleogene (K-Pg) boundary mass extinction is commonly attributed to the Chicxulub impact and/or the Deccan Traps (DT) volcanism, but the …
Microcrystalline calcite (micrite) dominates the sedimentary record of the aftermath of the Cretaceous–Paleogene (K–Pg) impact at 31 sites globally, with records ranging from the …

The effects of the Cretaceous‐Paleogene (K/Pg) mass extinction (~ 66 Ma) on marine primary and export productivity remain debated. We studied changes in carbon and nitrogen …
A high-resolution sedimentological and palynological study was performed in combination with biomarker-based organic geochemical temperature proxies TEX 86 and MBT′/CBT …
