The study area is located in the north of Yüğlük Mountain (Bolkar Mountains, Central Taurides). The aim of this research is to determine the location, stratigraphic and micropaleontological features of late Paleocene-Eocene units in the northern parts of Yüğlük Mountain. In this study, two different stratigraphic section were measured, and total of 93 samples were examined.
The oldest rock-units in the study area are Jurassic-Cretaceous carbonate rocks and Late Cretaceous ophiolitic melange. These units are unconformably overlain by late Paleocene sediments. Late Paleocene-Eocene units is the first unit of the Paleogene cover rocks. In the study, three formations have been distinguished from base to top. Berçin Formation consists of indistinctly layered conglomerates deposited in the river environment. Tosuntaş Formation; pink-grey coloured, medium-thick bedded, with fossil shell clasts and abundant benthic foraminifera, is represented by shallow marine-reefal limestones.
Küçükkoraş Formation is represented by abundant benthic foraminifera, clastic-limestone alternations at the lower part and at the upper parts by mudstone with sandstone-marl interlevels. Lithological features and fossil content indicate that the depositional environment is outer shelf. This units are unconformably overlain by Miocene units.
Based on stratigraphical relationships and the micropaleontological findings, it is identified that Berçin and the Tosuntaş formations are late Paleocene, and the Küçükkoraş formation is early-middle Eocene age.
