Tectono-stratigraphical investigation of Gülpınar - Afşar (N-NE of Taşkent - Konya)

The study area indicates that the geological properties, partly from the Central Taurus. The Geyik Dağı, Aladağ, Bolkar Dağı and Bozkır Units are located, which have various environment conditions with different stratigraphical, structural and metamorphical. properties. These units are bounded by a tectonic contact. Allochtonous Aladağ and Bolkar Dağı units were deposited during the period of Late Devonian and Late Cenonien and composed mainly of shelf type carbonates and clastic rocks as well as Cenonien age olistolith and olistostromal structured marine detrital materials. These units are located in the form of horizontal nappes over the Lutetian age marine clastics of the Geyik Dağı Unit at the northern part of the study area. They are similar in sedimantolgical proferties, but differ in stratigraphy, metamorphism and structure. The Bozkır unit is composed of Triassic and Cretaceous rocks. The unit includes platform sediments with various blocks and sections of alkaline sub-marine volkanics, tuff, diabase and serpantinites. It seems to be as a complex structure (melange). It is represented by the ophiolitic melange between autochton Geyik Dağı unit and allochtonous Aladağ unit. If the relationships between the units and the stratigrapy are considered, (a) they are made up a basin extended from the platform to ocean with the succession of Geyik Dağı, Aladağ, Boklar Mountain and Bozkır units South to the North in between Early Triassic and Cenonian, (b) The basin, might be called as North Tethys Ocean, was slabbed itself in the Bozkır unit and overlies Bolkar Mountain and Aladağ Units, dependent upon the closing in Late Cenonian; (c) it was estimated that Aladağ and Bolkar Mountain units were carried over the Geyik Dağı Unit together with ophioliths of closed basin at the end of the Ilerdian.
