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 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 ...
Late Cretaceous to Paleocene oroclinal bending in the central Pontides (Turkey)
Meijers, Maud J. M.; Kaymakcı, Nuretdin; van Hinsbergen, Douwe J. J.; Langereis, Cor G.; Stephenson, Randell A.; Hippolyte, Jean-Claude (2010-08-03)
The Turkish Pontide fold-and-thrust belt formed since the Paleozoic and is an important element in the Africa-Eurasia convergence and the resulting closure of the Neo-Tethys ocean. It has a peculiar arc-shaped geometry in its central part, along the Black Sea coast, which may have resulted from oroclinal bending. We have determined the vertical-axis rotation history of this area using paleomagnetism on Cretaceous to Eocene rocks from 47 sites and critically analyzed previously published data. We applied the...
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...
Late Cretaceous extension and Palaeogene rotation-related contraction in Central Anatolia recorded in the Ayhan-Buyukkisla basin
Advokaat, Eldert L.; van Hinsbergen, Douwe J. J.; Kaymakcı, Nuretdin; Vissers, Reinoud L. M.; Hendriks, Bart W. H. (2014-11-18)
The configuration and evolution of subduction zones in the Eastern Mediterranean region in Cretaceous time accommodating Africa-Europe convergence remain poorly quantitatively reconstructed, owing to a lack of kinematic constraints. A recent palaeomagnetic study suggested that the triangular Central Anatolian Crystalline Complex (CACC) consists of three blocks that once formed an similar to N-S elongated continental body, underthrusted below ophiolites in Late Cretaceous time. After extensional exhumation a...
