Structural interpretation of five 2D seismic sections acquired by TPAO is carried out in the Adıyaman region of Southeast Anatolia. The sections are geological calibrated with stratigraphic logs of five boreholes. This study has resulted in the discovery of a previously undefined fault, herein named as Şambayat Fault. The fault is a NW-SEtrending structure that parallels the Bozova Fault and comprises several parallel fault segments. The structural maps of Cretaceous Sayındere and Karababa formations are also prepared and suggest that their sedimentation was controlled by the Şambayat Fault; it is therefore suggested that the Şambayat Fault was active during at least Campanian and because it appears not affecting the Middle Eocene-Oligocene Gaziantep Formation, its activity ceased by then. The segments of the Şambayat Fault is cut and displaced by the Adıyaman Fault. The correlation of these segments on either side of the Adıyaman Fault indicates a total sinistral displacement of about 4400 m. The Şambayat Fault is buried beneath younger sediments and has no surface expression suggesting its activity. Therefore, careful interpretation of seismic sections would be a useful method to identify and map buried structures that may have important implications on the geological evolution of a given region.

Earthquake focal mechanism analysis of Central Anatolia Birsoy, Seda; Özacar, Atilla Arda; Department of Geological Engineering (2018) Anatolian interior is characterized by large lateral and vertical displacements and a complex tectonic history. Especially, Central Anatolia is located between escape tectonics in the east and extensional deformation in the west. The nature of this transition is still under much debate and requires detailed analysis of active tectonic stresses within the region. In this study, regional moment tensor inversion is performed for 29 earthquakes with M>3.5 recorded between 2013-2015 by a temporary broadband seis...
Identification of morphometric properties of basins located on western part of NAFZ Sarp, Gülcan; Toprak, Vedat; Düzgün, H. Şebnem; Department of Geodetic and Geographical Information Technologies (2012) This study aims to investigate tectonic activity levels and development stages of the tectonic and hydrologic basin areas located on western part of the main trace of the North Anatolian Fault Zone (NAFZ) using quantitative measurement techniques. The basins investigated are Bolu, Yeniçağa, Dörtdivan, Çerkes, Ilgaz and Tosya. The methodology includes application of six morphometric indices (Basin Shape, Hypsometric curve and Hypsometric Integral, Sinuosity of Mountain Fronts, Stream Length Gradient Index, V...
Neo- and seismo-tectonic characteristics of the Yenigediz (Kütahya) area Gürboğa, Şule; Koçyiğit, Ali; Department of Geological Engineering (2011) Erdoğmuş-Yenigediz graben is one of the major structural elements of Akşehir-Simav Fault System (ASFS), which is a major extensional structure in the southwestern Anatolian extensional neotectonic province (SWAEP). It is about 6-10-km-wide, 15-km-long and approximately ENE-trending and is actively growing structure as indicated by the 1970.03.28 (Mw= 7.2) Gediz earthquake. The graben is characterized by two distinct units, separated by an angular unconformity: (i) Miocene-middle Pliocene Arıca formation and...
Kinematics of Delice-Kozaklı fault zone (North Central Anatolia, Turkey) Tokay, Bülent; Bozkurt, Erdin; Kaymakcı, Nuretdin; Department of Geological Engineering (2015) The Central Anatolian Crystalline Complex (CACC) forms a part of Alpine orogenic belt in Turkey and incorporates three major massifs and several basins that developed during extension commenced by the Late Cretaceous. They were deformed during subsequent collision of Anatolide-Tauride Platform and Pontides. The deformation of the region has resulted in the break-up of the CACC along major deformation (fault) zones. The present study aims to test existence of one of these fault zones, namely Delice-Kozaklı f...
Active tectonics and kinematics of Fethiye-Göcek Bay, SW Turkey Tosun, Levent; Kaymakcı, Nuretdin; Department of Geological Engineering (2018) Tomographic studies conducted in Eastern Mediterranean region reveal that Pliny-Strabo Trench corresponds to a tear known as "STEP" (Subduction Transform Edge Propagator) fault connecting the Aegean and Cyprean trenches along the northern edge of the northward subducting African lithosphere. Recently, it is claimed that Fethiye-Burdur Fault Zone, which interpreted as a sinistral transtensional shear zone, is the northeaster continuation of this fault. In order to test this hypothesis, a rigorous study aimin...
