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, and the Intra-Pontide Suture Zone, in Anatolia, represent remnants of the same elongate oceanic basin.


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...
Early and Middle Triassic trends in diversity, evenness, and size of foraminifers on a carbonate platform in south China: implications for tempo and mode of biotic recovery from the end-Permian mass extinction
Payne, Jonathan L.; Summers, Midi; Rego, Brianna L.; Altıner, Demir; Wei, Jiayong; Yu, Meiyi; Lehrmann, Daniel J. (Cambridge University Press (CUP), 2011-06-01)
Delayed biotic recovery from the end-Permian mass extinction has long been interpreted to result from environmental inhibition. Recently, evidence of more rapid recovery has begun to emerge, suggesting the role of environmental inhibition was previously overestimated. However, there have been few high-resolution taxonomic and ecological studies spanning the full Early and Middle Triassic recovery interval, leaving the precise pattern of recovery and underlying mechanisms poorly constrained. In this study, w...
Stratigraphy and pre-Miocene tectonic evolution of the southwestern part of the Sivas Basin, Central Anatolia, Turkey
Dirik, K; Göncüoğlu, Mehmet Cemal; Kozlu, H (1999-07-01)
In central Anatolia there are several important basins developed mainly after closure of the northern branch of Neotethys. These are the Haymana, Tuzgolu, Ulukisla, Kizihrmak, Cankiri-Corum and Sivas basins. The Sivas Basin is located in the eastern part of central Anatolia between the Central Anatolian Crystalline Complex (CACC) in the north and Taurides in the south. The basement to the southeastern part of the basin consists of recrystallized limestone and clastics of the Permian-Lower Cretaceous Bunyan ...
Late Cretaceous Arc Magmatism in the Southern Central Pontides: Constraints for the closure of the Northern Neotethyan branches
Sayıt, Kaan; Cemal Göncüoğlu, M.; Ellero, Alessandro; Ottria, Giuseppe; Frassi, Chiara; Marroni, Michele; Pandolfi, Luca (2022-01-31)
In the southern Central Pontides in northern Turkey the remnants of two Neotethyan oceanic basins, currently represented by the Intra-Pontide and the Izmir-Ankara-Erzincan sutures, and the interposing continental microplate (i.e., the Sakarya Composite Terrane) are completely dissected by the North Anatolian Shear Zone (NASZ). Within the resulting kilometre-scale, strike-slip fault-bounded blocks, several Late Cretaceous arc-type magmatic units have been detected. In this paper, we present new geochemical d...
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...
