New insights on the late Maastrichtian and Danian paleoenvironment from integrated magnetostratigraphy and multiproxy analyses of a shallow marine carbonate section, northeastern Brazil

The late Maastrichtian (Late Cretaceous) and Danian (early Paleogene) are punctuated by abrupt climatic perturbations modulated by global-scale events such as asteroid impacts (Chicxulub) and large igneous provinces (LIPs; e.g., Deccan Traps, North Atlantic Igneous Province). In this work, we analyzed magnetostratigrap...

Impact of the Cretaceous-Paleogene event on sedimentary organic matter in southern high-latitude regions

The Cretaceous–Paleogene (K/Pg) boundary marks one of Earth’s significant mass extinctions, disrupting terrestrial and marine ecosystems. We investigate sedimentary organic matter and geochemical proxies from two high-latitude K/Pg sections: El Puesto (continental, Chilean Patagonia) and Filo Negro (marine, Seymour Isl...
