Tectono-stratigraphical investigation of Çetmi ? Bolay (e-se of Kaşkent?Konya)

The tectonic units, which are known namely as Aladağ, Bolkar and Bozkır units of investigated areas are crop out in the central Taurides, have tectonic contact relations one another and individually has different rock units that were formed in different environmental conditions indicative with their stratigraphical, structural and metamorphism characteristics. Aladağ and Bolkar Dağı units, which mainly made up of late Devonian-late Cretaceous shelf type carbonates and detritics and Senonian age marine clastics comprising olistoliths and olistostromes, are seen as horizontal nappes on the Lutetian age marine clastics belongs to Geyikdağ unit that whole part of it can not be seen in the area. These two tectonic units which have similar aspects, shows difference each other with their stratigraphy, metamorphism conditions and structural properties. The Bozkır unit looks like a mega mélange and is represented by Triassic-Cretaceous basin-slope and less platform sediments and also represented by different size of blocks and slices derived from basic submarine volcanics. It is thought that an oceanic basin were formed between Geyik dağı and Aladağ units represented by ophiolitic mélange including ophiolites, pelagic carbonates interbedded with syphilitic volcanics during the late Maastrichtian-Illardian (Late Paleocene-early Eocene) period. The mélange is seen as tectonic slices with different thicknesses between Geyik dağı, Bolkar dağı and Aladağ tectonic units. By interpreting the stratigraphical properties and relationships of the tectonic units with one another; (a) during early Triassic-Senonian Geyikdağı, Aladağ, Bolkar and Bozkır units arranged in order from South to the North formed a basin starting from platform to the deep marine-ocean; (b) related to the closing of the basin, which could be named as Northern Neo-Tethys ocean, during late Senonian, the Bozkır unit initially sliced and thrusted onto the Bolkardağı and Aladağ units; (c) It is thought that, the Aladağ and Bolkar dağı units with the ophiolites of the closing basin by the end of Ilardian, and also by carrying the Bozkır unit on top, all tectonically emplaced onto the Geyikdağı unit.Key words : Geyik dağı, Bolkar dağı, Aladağ, Bozkır units, Konya
