Abstract

The Earth's climate system has experienced many changes throughout the Cenozoic Era. One of the most remarkable changes was witnessed during the Paleogene when conditions changed from greenhouse to an icehouse planet. A series of abrupt, but short-lived (<300 ka) episodes of widespread warming, termed "hyperthermals" occurred during this period. However, a transient global warming event, which differed in many aspects from the other hyperthermals took place: the Middle Eocene Climatic Optimum (MECO). This project will focus on understanding the climatic mechanisms that took place during this transient period of global warming through a semi-quantitative (XRD) and comparative analysis from minerals and clay minerals in the Ross Sea (Antarctica) and in the Neo-Tethys (Turkey). The clay minerals have a fundamental aspect of expressing climatic changes in the Southern Ocean and on preserved terrestrial sections, which make us take a step further to work in collaboration with the United States Geological Survey to perform the most up-to-date analysis and to obtain best results.
