Abstract
The aim of this study to determine stratigraphic, sedimentological and petrographic characteristics of the Upper Paleocene - Lower Eocene Güney formation in the Ereğli - Ulukışla 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 Güney 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 Güney 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 Kardeşgediği station, the presence of channel fillings, slump structures, and pebbles indicate that the sequence shows convergent turbidite character. However, in the vicinity of Ovacık - Güney village and Tatlıpınar 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 Güney formation transitions laterally and vertically overlies the agglomerate unit of the Ulukışla formation and turbiditic sandstone - shale units of the Halkapınar 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.
