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 fault zone. Several structures are mapped and their geometric analyses are carried out. The structures include: (i) a syncline with axis trending in 070º; (ii) syncline and anticline with axes trending in 160º; (iii) approximately NW−SE-trending plunging fold sets; (iv) E−W-trending anticline and syncline; (v) NW−SE-trending overturned folds; (vi) a NW−SE-trending (130º) and NNW−SSE-trending right-lateral strike-slip faults and (vii) WNW−ESE-trending north-verging reverse faults. Several fault plane data has been collected from the basement rocks and basin infill for kinematic analysis. Paleostress analysis and the stratigraphic data suggests two deformation phases: (1) NW−SE compression that lasted by middle Oligocene and (2) a post-Oligocene NNE−SSW compression that gave rise to a dextral transpressional deformation. The common results of the geometric and kinematic analyses of the structural data argues for the existence of the Delice-Kozaklı fault zone and that the study area has stayed within same deformation zone during NW−SE and then NNE−SSW compressional phases.

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...
Paleogene evolution and demise of the proto-Paratethys Sea in Central Asia (Tarim and Tajik basins): Role of intensified tectonic activity at ca. 41 Ma Kaya, Mustafa Yücel; Dupont-Nivet, Guillaume; Proust, Jeannoel; Roperch, Pierrick; Bougeois, Laurie; Meijer, Niels; Frieling, Joost; Fioroni, Chiara; Altıner, Sevinç; Vardar, Ezgi; Barbolini, Natasha; Stoica, Marius; Aminov, Jovid; Mamtimin, Mehmut; Guo Zhaojie, Guo Zhaojie (Wiley, 2019-06-01) The proto-Paratethys Sea covered a vast area extending from the Mediterranean Tethys to the Tarim Basin in western China during Cretaceous and early Paleogene. Climate modelling and proxy studies suggest that Asian aridification has been governed by westerly moisture modulated by fluctuations of the proto-Paratethys Sea. Transgressive and regressive episodes of the proto-Paratethys Sea have been previously recognized but their timing, extent and depositional environments remain poorly constrained. This hamp...
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...
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...
Rapid cooling history of a Neotethyan ophiolite: Evidence for contemporaneous subduction initiation and metamorphic sole formation PARLAK, OSMAN; Dunkl, Istvan; KARAOĞLAN, FATİH; Kusky, Timothy M.; Zhang, Chao; Wang, Lu; Koepke, Juergen; Billor, Zeki; Hames, Willis E.; ŞİMŞEK, EMRAH; Simsek, Gokce; ŞİMŞEK, TUĞÇE; Ozturk, Selena Ezgi (Geological Society of America, 2019-11-01) The Beywhir-Hoyran Nappes, including Mesozoic carbonate platform rocks, deepsea sediments, and ophiolite-related units, crop out extensively on the western limb of the Isparta Angle in the Central Taurides, Turkey. The ophiolite-related rocks are represented by variably serpentinized harzburgitic mantle tectonites, tectonically underlain by a subophiolitic metamorphic sole and melange. The harzburgitic mantle tectonites and metamorphic sole are intruded by undeformed isolated dikes. Protoliths of the metamo...
