Post-late cretaceous rotational evolution of neotethyan sutures around Ankara region Özkaptan, Murat; Kaymakcı, Nuretdin; Özacar, Atilla Arda; Department of Geological Engineering (2016) The central Anatolia comprises various continental fragments belonging to Laurasia at the north and Gondwana at the south. These amalgamated continental fragments (micro continents) delineated by ophiolitic remnants of Tethyan oceanic lithosphere which were consumed due to ~N to S convergence. Around Haymana Basin the closure of the Neotethys Oceans lead to amalgamation of the Pontides (Laurasian affinity) in the north, Tauride and Kırşehir blocks (Gondwana affinity) in the south. The main purpose of this s...
Post miocene tectonic of çeltikçi graben, southern margin of galatian volcanic province, Central Anatolia Berberoğlu, Umur; Rojay, Fuat Bora; Department of Geological Engineering (2019) The Çeltikçi basin is located at the southern margin of a volcanic terrain known as “Galatian Volcanic Province” located on top of Cretaceous accretionary prism and to the south of North Anatolian Fault. The aim of this study is to investigate the difference in the style and intensity of deformation between Plio-Quaternary clastics and Miocene units. The units exposed in the area are classified as, from oldest to youngest, Miocene volcanics, Miocene Çeltikçi formation, Plio-Quaternary and Quaternary units. ...
Late Eocene evolution of the Cicekdagi Basin (central Turkey): Syn-sedimentary compression during microcontinent-continent collision in central Anatolia Gulyuz, Erhan; Kaymakcı, Nuretdin; Meijers, Maud J. M.; van Hinsbergen, Douwe J. J.; Lefebvre, Come; Vissers, Reinoud L. M.; Hendriks, Bart W. H.; Peynircioglu, A. Ahmet (2013-08-16) The Central Anatolian Crystalline Complex (CACC) exposes metasediment rocks overlain by Cretaceous ophiolites and intruded by granitoids. Following late Cretaceous exhumation of its high-grade metamorphic rocks, the CACC started to collide with the Central Pontides of southern Eurasia in the latest Cretaceous to Paleocene. Here, we present the sedimentary, stratigraphic and tectonic evolution of the Cicekdagi Basin, located in the northwest of the CACC. Magnetostratigraphic dating, supported by Ar-40/Ar-39 ...
Late Jurassic amphibolite-facies metamorphism in the Intra-Pontide Suture Zone (Turkey): an eastward extension of the Vardar Ocean from the Balkans into Anatolia? Marroni, M.; Frassi, C.; Göncüoğlu, Mehmet Cemal; Di Vincenzo, G.; Pandolfi, L.; Rebay, G.; Elero, A.; Ottria, G. (2014-09-01) The palaeogeography of Neotethys during its closure is still a matter of debate. This study provides new insights into the Neotethys closure by the discovery in the Intra-Pontide Suture Zone (Turkey) of an accretionary complex that recorded a Late Jurassic (c. 163 Ma) amphibolite-facies metamorphism. Results are discussed in the framework of the accretionary events that occurred at the southern margin of Laurasia. The resulting picture supports a new model in which the Vardar suture zone, in the Balkans, an...
Post-Triassic evolution of Central Pontides: evidence from Amasya region, northern Anatolia Rojay, Fuat Bora (1995-12-01) The Central Pontides is an orogenic belt evolved since Triassic by the progressive closure of Paleo- and Neo-Tethys oceans, which is bounded by the IzmirAnkara-Erzincan Suture (Northern Neotethyan Suture) from the south. The post-Triassic Neo-Tethyan evolution in Amasya region started with Liassic transgression on the rifted pre-Liassic basement rocks. Later, the initial rifting failed and the platform was uplifted. The uplifted platform turned into an open-marine depositional realm as recorded by the depos...
