Abstract: The study area lies between Sarız-Şarkışla-Gemerek-Tomarza. Geyik Dağı Unit is situated in the southof the region and comprises a regular sequence ranging from Cambrian to Tertiary. This unit is relatively autochthonous with respect to allochthonous units.Allochthonous rock units of Paleozoic-Mesozoie age crop out towards north which preserve their primary properties,and are locally metamorphosed. These are: Kireçliyayla Nappe including Triassic-U- Cretaceous carbonates, Belören Nappe consisting of Triassic-Cretaceous rocks, Aygörmezdağ Nappe comprising a sequence from U. Devonian toU. Cretaceous, and Hmzırdağı Nappe consisting of metamorphosed Permian-L. Cretaeous rocks. The uppermostparts of some of these nappes are formed by the ophiolitic melange, and all the nappes are overlain by an ophiolitenappe. Emplacement age of the allochthonous units is Late MaestrichtianThe Tertiary formations unconformably overlying the allochthonous units crop out over extensive areas. ThePaleocene-Eocene formations to the nort of the region, which are olistostromal in character, indicate that thetectonic stability which prevailed after the emplacement of the allochthon was disrupted once again.
