Abstract: The Eocene climatic system experienced an important transition from warm Paleocene greenhouse to icehouse Oligocene conditions.This transition could first appear as a long-term cooling trend but, at an up-close look, this period is a complex combination of climatic events and,for most of them, causes and consequences are still not fully characterized. In this context, a study has been carried out on the middle Eocene sedimentary succession of the Contessa Highway section, central Italy, which is proposed as the Global Stratotype Section and Point(GSSP)for the Lutetian/Bartonian boundary at the top of the Chron 19n, with an astronomically calibrated age of 41.23 Ma. Through a cyclostratigraphic analysis of the rhythmic sedimentary alternations and combination with the results of time series analysis of the proxy record, we provide an orbital tuning of the middle Eocene and astronomical calibration of the bio-magnetostratigraphic events (particularly for the C19n/C18r Chronboundary) recognized at the Contessa Highway section.
