The aim of this study to determine stratigraphic, sedimentological and petrographic characteristics of the Upper Paleocene - Lower Eocene Guney formation in the Eregli - Ulukisla Basin based on the lithological and environmental interpretations related to petroleum source and reservoir rock properties of it. For this purpose, the geological characteristics of the Guney formation and its relations with other units were followed by field observations and the unit was investigated by making a stratigraphic cross section from bottom to top. In addition, during the field studies, four (4) scaled stratigraphic sections (OSK) were formed and fifty - two (52) sandstone samples were taken from these OSKs. The Guney formation starts with conglomerates at the basement and continues as sandstone - shale alternation. The fact that the sand size material is more than the clay size material, the sandstone layers are thick (at least 2 m) around the Kardesgedigi station, the presence of channel fillings, slump structures, and pebbles indicate that the sequence shows convergent turbidite character. However, in the vicinity of Ovacik - Guney village and Tatlipinar ridges, shales having an average layer thickness of 30 cm (thick) and sandstones up to 3 - 5 cm (thin) and shales are denser than sandstones show the formation has divergent character. The Guney formation transitions laterally and vertically overlies the agglomerate unit of the Ulukisla formation and turbiditic sandstone - shale units of the Halkapinar formation. The Aktoprak formation passes laterally and vertically over the Formation. Petrographic studies show that the formation sandstones are lithic arenite and feldspathic arenite and are deposited in the fore - arc basin.
