The unit, that is widely exposed in the region, is named for the first time “Seydiler Formation”.  </span> <span style="font-size: 12px;">This formation conformably overlies the Lutetian Gürleyikdere Formation at the base while it is overlain  </span> <span style="font-size: 12px;">by Recent and Quaternary alluvium deposits with an unconformity at the top. Seydiler Formation is  </span> <span style="font-size: 12px;">represented by thin bedded sandstone-marl alternations at the base and by medium to thick-bedded, dark  </span> <span style="font-size: 12px;">grey marls in the upper parts. The thickness of the formation varies from 30 to 215 meters.  </span> <span style="font-size: 12px;">Paleontological examinations were carried out on 184 samples collected from 7 stratigraphic sections.  </span> <span style="font-size: 12px;">Overall, 19 taxa belonging to 11 ostracod genera in 9 different families were determined. Among the   </span> <span style="font-size: 12px;">families Cytherellidae, Bairdiidae and Krithidae, were the dominant genera. One species  </span> <span style="font-size: 12px;">“Echinocythereis anatolica n.sp.” is proposed as a new species. Cytherella and Krithe are very abundant  </span> <span style="font-size: 12px;">and dominant within the ostracoda assemblage. Based on the ostracod assemblage examined, the age of  </span> <span style="font-size: 12px;">this unit is assigned as Bartonian-Priabonian. This assignment is also supported by the dating of  </span> <span style="font-size: 12px;">planktonic foraminifers, nannoplanktons and dinoflagellates. All paleontological data of the study area  </span> <span style="font-size: 12px;">indicate neritic to bathyal marine depositional conditions with normal salinities. </span> </p>}, number={1}, publisher={TMMOB Jeoloji Mühendisleri Odası}
