Although the North Anatolian Shear Zone is one of the main lithospheric-scale strike-slip deformation zone in the world, playing a prominent role in the complex geodynamic interaction among the Eurasian, Anatolian and Arabian plates, the onset time of its activity remains highly controversial. Here, we tackle this issue by utilizing nannofossil biostratigraphy on deposits from the Tacilar basin, a pull-apart basin that we have identified inside the North Anatolian Shear Zone overprinting the Intra-Pontide suture zone. The syn-tectonic sedimentary succession of the Tacilar basin developed completely during the early Eocene (Ypresian; CNE4-CNE5 Zones). The strike-slip faulting related to the initial onset of the North Anatolian Shear Zone can likely be constrained within the Ypresian, suggesting that the westward escape of the Anatolian plate along the North Anatolian Shear Zone started in the early Eocene.


Formation and emplacement ages of the SSZ-type Neotethyan ophiolites in Central Anatolia, Turkey: palaeotectonic implications
Yaliniz, MK; Göncüoğlu, Mehmet Cemal; Altıner, Sevinç (2000-04-01)
Isolated outcrops of ophiolitic rocks, termed the Central Anatolian Ophiolites, are found as allochthonous bodies in the Central Anatolian Crystalline Complex, that represent the metamorphosed passive northern edge of the Tauride-Anatolide Platform, central Turkey. In terms of pseudostratigraphic relationships of the magmatic units and their chemical designation, the Central Anatolian Ophiolites exhibit a supra-subduction zone (fore-arc) setting within the Vardar-Izmir-Ankara-Erzincan segment of the Neoteth...
Geological and Geochemical Evolution of the Quaternary Suphan Stratovolcano, Eastern Anatolia, Turkey: Evidence for the Lithosphere-Asthenosphere Interaction in Post-Collisional Volcanism
Özdemir, Yavuz; Güleç, Nilgün Türkan (Oxford University Press (OUP), 2014-01-01)
The Suphan stratovolcano is one of the major Quaternary eruption centers of post-collisional volcanism in eastern Anatolia, located in the zone of convergence between the Arabian and the Anatolian plates. We document the geological and geochemical evolution of Suphan in terms of volcanostratigraphy, geochronology (Ar-40-Ar-39), isotope composition (Sr, Nd, Pb) and bulk-rock geochemistry. Our new Ar-40-Ar-39 data, along with previously published K/Ar ages, indicate an age of 0 center dot 76-0 center dot 06 M...
Evolution of the Neotethyan branches in the Eastern Mediterranean Petrology and ages of oceanic basalts
Göncüoğlu, Mehmet Cemal; Sayıt, Kaan; Uzunçimen Keçeli, Seda (null; 2015-10-27)
The Anatolian Peninsula in the Eastern Mediterranean includes remnants of the Proto-, Paleo-, Neo- and Para-Tethys oceans. From these, the Neotethys with its various branches has been studied relatively well. Disregarding the embayments of the major oceanic strands, three main oceanic branches are distinguished by the presence of ophiolitic suture belts, separating terranes of continental crust origin (Fig. 1). From S to N these are the Southern branch of Neotethys, the ...
Upper Cretaceous Radiolarian ages from an arc-back-arc within the Yuksekova Complex in the southern Neotethys melange, SE Turkey
TEKİN, UĞUR KAĞAN; Ural, Melek; Göncüoğlu, Mehmet Cemal; ARSLAN, MEHMET; KÜRÜM, SEVCAN (2015-02-01)
The Yuksekova complex in SE Turkey is a part of a continuous belt of ophiolites and subduction-accretion complexes that stretches from Troodos in the west to Oman in the east, representing the remnants of the Southern Branch of Neotethys. This complex mainly comprises a tectonically chaotic assemblage of basaltic dykes and pillow lavas associated with radiolarian cherts, shales and pelagic limestones. Detailed petrological work on submarine basaltic lavas from Elazig-Malatya area in SE Turkey revealed the p...
Noble gases and rock geochemistry of alkaline intraplate volcanics from the Amik and Ceyhan-Osmaniye areas, SE Turkey

The SE part of Turkey is characterized by a transtensional regime within the complex collision zone between the Anatolian, Arabian and African plates, which is bounded by two main faults, Dead Sea Fault and its splays on east and the Karasu Fault on west. In this tectonic and geodynamic context developed the Amik and further North, Erzin and Toprakkale districts, which are located onshore the Iskenderun Gulf, with the occurrence of a widespread and young alkaline volcanism dated from 1.57 to 0.05 Ma in Amik...
