Öğe A Description of Terrestrial Neogene Deposits in the Beykoyu-Gokceyazi Area (Eregli, Konya, Central Turkey)(SPRINGER INT PUBLISHING AG, 2014) Ozkan, Ali Mujdat; ComlekcIler, FuatThe stratigraphic sequence in the Beykoyu-GokceyazI area, central Turkey, starts with the Palaeocene-lower Eocene Guneydagi Formation, including limestone interbedded with calcirudite, calcarenite, and marl. An angular unconformity separates the unit from the overlying Beykoyu Formation, which has two members: Kabaktepe gypsum and Kayalidagtepe stromatolitic limestone. A Miocene lacustrine environment is inferred for the deposition of the Beykoyu Formation, based on the existence of blue-green algae (Schizothrix sp., Scytonema sp., and Phormidium sp.) as well as green algae (Chara sp.), lacustrine Gastropoda (Planorbarius sp.), and lacustrine ostracodes. The sequence continues with the upper Pliocene-Holocene Kuskuncuk Formation, containing alternations of conglomerate, sandstone, and mudstone, with caliche bands in some levels, which were deposited in alluvial fan and braided stream environments. Quaternary alluvium is the youngest unit in the sequence.
