In this research, detailed petrographic and stratigraphic examinations of the units in the area between Saimbeyli and Gürleşen-Tülü villages (Adana) were presented. In the study area, Ordovician aged shale and schist shale alternation of the Armutludere formation form the basement. The Ayıtepesi formation, which consists of an alternation of Early Devonian aged sandstone, mudstone, shale and clayey limestone unconformably overlies this unit. Above, the Şafaktepe formation, which composed of the Middle Devonian dolomitized limestones conformably overlying Ayıtepesi formation. On top of this unit, the Gümüşali formation consisting of an alternation of Late Devonian aged sandstone, shale, limestone deposited concordantly. The Permian age Yığılıtepe formation consisting of limestones is discordant on the Gümüşali formation. The Lower Triassic age Katarası formation composed of sandstone, marl and clayey limestone overlies this formation concordantly. The Jura-Cretaceous age Köroğlutepesi formation, consisting of grey and beige limestones, is unconformably sitting on the Katarası formation. As a result of petrographic studies carried out on 21 thin sections compiled from the region, it was revealed that clastic sediments in the area are generally re-worked in a low-energy environment, sand-rich components are not washed well and most of the carbonate rocks in the region are microsparitic.
