Popis: The studied area is restricted by the Niğde group at the north, Bolkar group at the south and Ecemiş fault zoneat the east. The Niğde group is composed of Aşıgediği and Çamardı formations in the studied area. Üçkapılı granodiorite isintruded into all of these rock units. Yeniköy formation which consists of sedimentary rocks, overlies the Niğde group. TheBolkar group is made of Permian aged marbles and schists. The Alihoca ophiolite complex overlies this group with a tectoniccontact. The Horoz granodiorite intrudes into the Bolkardağı marbles and quartz-porphyry dykes cut the ophiolitic rocks. TheAladağ group, which is located at the eastern part of Ecemiş fault, is composed of Akdağ and Gökbel formations. The Aladağophiolitic melange has a sedimentary contact with the carbonaceous rocks that forms the basement. The Aladağ ophioliticnappe overlies the former with a tectonic contact. The Ulukışla-Çamardı Tertiary basin overlies many different tectonic units.The volcano-sedimentary and plutonic rocks which crop out at the north are developed on the Niğde massif sedimentary rockscropping out at the south are developed on the Bolkardağı marbles and the volcano-sedimentary rocks of the central part, aredeveloped on the Alihoca ophiolite complex. All the three sections came in conjunction with the Upper Eocene tectonicmovements.The basement of the Tertiary basins starts with Bolkardağı marbles and Kalkankaya formation, which overlie theophiolite complex with angular unconformity, at the southern section. It ends with Yağbağ and Kırkpınar formations. ThePlio-Quatemary actual sediments cover these units The rock units of Cretaceous to Middle Eocene are observed in thecentral section. This section is made of Kırkgeçit. Tabaklı, Ardıçlı, Hasangazi formations and their members. The Zeyvegediğianhydrite, which is digo-Miocene, overlies these units with angular unconformity. The Kurtulmuş, and Kızılöz formations,Ilıcadere basalt and actual sediments cover all the former units. North section also consists of Cretaceous to Middle Eocenerock units. This section is composed of Ömerli, Yeniköy, and Unlukaya formations, Başmakçı limestone, Karlık basalt. Alıçlıandesite, South and Çaykavak formations, Elmalı syenite-Porphyr, diabase dyke and Kaletepe trachyte. Finally, the Kaletepetrachyte cuts all of these units. Oligo-Miocene aged Fındıklı formation covers them with an angular uncomformity andproceeds with Miocene Burç formation. It ends up with Çanaktepe formation. Havuzlu tuffite, Gökbez formation, İkiztepeignimbrite and actual sediments at the top. The basin has experienced three different compression stages, which occured inUpper Eocene-Lower Oligocene, Upper Miocene and Upper Pliocene
