Abstract

The Early Paleogene was the time when the Earth experienced a pronounced warming trend that peaked with the Early EoceneClimatic Optimum (EECO; 52 to 50 Ma). This long-term climate trend is punctuated by short-lived warming events such as the Paleocene-Eocene Thermal Maximum (PETM), the ELMO event (Eocene Layer of Mysterious Origin), and additional events. The available paleoclimatic records suggest that the Earth climate system, after the EECO, underwent a cooling trend eventually crossing a major threshold at the base of the Oligocene, when the modern icehouse world became definitively established. Here, we present integrated stratigraphic data from several sections located in the Venetian Southern Alps (Italy), spanning from the K-T boundary to Late Eocene. These results improve our knowledge on the Paleogene pelagic sediments cropping out in the Veneto region and could help in shading light on the Paleogene paleoclimate.
