The Stratigraphy and The Tectonics of Özvatan-Felahiye (Kayseri) Region

Abstract: The stratigraphy in the investigated area shows different properties in the northern and the southern parts of Kermelik village.Malak formation of Lutetian age, which is represented by terrestial and marine fades, overlies unconformably the basement, Akdağmetamorphics and Kuştepe gabbro, Silahtar meta granite and Atderesifoid syenite intruded in them. This formation is overlain byKaracaören formation which is represented by limnic and fluvial fades of Late Miocene - Early Pliocene age with angular unconformity. Subaerial basaltic lava flows which outcrop around Amar at village accompanies to this sedimentation. This succession endswith terrestrial elastics belonging to Sızır formation of Early Pliocene - Quaternary age.The oldest rock unit in the southeast of Kermelik village is Tuzla formation of Late Cretaceous - Early Paleocene age which isrepresented by low grade metamorphosed pelagic limestone and volcanics. This unit overthrusts to Cevizcik formation of Oligoceneage which is represented by terrestrial elastics and gypsum.The metamorphic basement and its Tertiary cover have different structural features with respect to each other in t lie area. Thestructural elements of Tertiary units in the area are thrust faults, strike - slip faults and axial plane folds which were created under acompressional regime inNeotectonic period. After that, several normal faults developed during the releasing period of the region.
