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. The fault-controlled talus to fan deposits and Quaternary alluvial deposits are the youngest units in the area. The dip strike measurements of bedding planes and the analysis of fault slip data were used for the post-Miocene deformational studies. The intense faulting and folding are observed for the Miocene units. However, the Plio-Quaternary clastics are gently folded and poorly faulted. The field data and fault plane slip data analyses revealed that there is compression during post-Miocene to Late Pliocene period. However, during Quaternary and onwards the operating deformation is extension.

Late quaternary sedimentation in the strait of bosporus: high-resolution seismic profiling Alavi, Seyed Naeim; Okyar, Mahmut; Köse, Timur (Elsevier BV, 1989-10) Uniboom profiling supported by borehole data in the southern part of the Bosporus revealed that close to its banks Holocene sediments are underlain by the faulted slopes of a valley cut in many places into the Palaeozoic bedrock. Away from the banks the sediments thicken and their boundary with the underlying Pleistocene deposits is defined by an erosional surface at about the 80 ms TWT. This surface marks the initiation of marine currents in the valley as its deeper parts began to be submerged in the late ...
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...
Late Campanian Maastrichtian evolution of orbitoidal foraminifera in Haymana Basin succession Ankara Central Turkey Özcan, Ercan; Altıner, Sevinç (1997-01-01) In Central Anatolia, a thick sedimentary succession composed of deep-water turbiditic units represented by marl-shale, sandstone, olistostromal horizons and carbonates crops out. This succession constitutes the lower part of so-called Haymana Basin spanning the Santonian (?)/Campanian-Eocene time interval. Evolution of Lepidorbitoides and Orbitoides concerning embryonic features and the initial chamber arrangement has been investigated in the Late Cretaceous part of this succession. Previously unrecognized ...
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...
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...
