Abstract

The Paleogene (Paleocene, Eocene and Oligocene, from 65.5 to 23.03 Ma) was a transition period of the Earth's climate system that experienced changes from greenhouse to icehouse conditions. During this period, a series of abrupt, but short-lived (<300 ka) episodes of widespread warming, termed "hyperthermals" occurred. However, also during this period, a transient global warming event, which differed in many aspects from the other hyperthermals took place: the Middle Eocene Climatic Optimum (MECO). The main objective of this project is to register and understand the climatic mechanisms which occurred during the MECO through semi-quantitative (XRD) and comparative analyzes from minerals and clay minerals in the West Equatorial Atlantic (Ceara Rise) and in the Neo-Tethys (Turkey).
