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.

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...
Origin and significance of a quartz tourmaline breccia zone within the central anatolian crystalline complex, Turkey Demirel, Serhat; Göncüoğlu, Mehmet Cemal; Department of Geological Engineering (2004) The aim of this study is to investigate the petrography, geochemistry and evolution of quartz-tourmaline-rich rocks occurring in a wide breccia zone within the Late Cretaceous Kerkenez Granitoid (Central Anatolian Crystalline Complex (CACC), Turkey). The approximately 40-m wide main breccia zone has a NE-SW trend and is characterized by intense cataclastic deformation. The breccia zone can be traced several kilometers towards the west and generally occurs as tourmaline-filled faults and 1mm-30cm-thick veins...
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...
Active tectonics and kinematics of Fethiye-Göcek Bay, SW Turkey Tosun, Levent; Kaymakcı, Nuretdin; Department of Geological Engineering (2018) Tomographic studies conducted in Eastern Mediterranean region reveal that Pliny-Strabo Trench corresponds to a tear known as "STEP" (Subduction Transform Edge Propagator) fault connecting the Aegean and Cyprean trenches along the northern edge of the northward subducting African lithosphere. Recently, it is claimed that Fethiye-Burdur Fault Zone, which interpreted as a sinistral transtensional shear zone, is the northeaster continuation of this fault. In order to test this hypothesis, a rigorous study aimin...
Analysis of seismic anisotropy across Central Anatolia by shear wave splitting Pamir, Dilekcan; Özacar, Atilla Arda; Department of Geological Engineering (2014) Central Anatolia plays a significant role to connect the theories on the ongoing tectonic escape, the African Plate subduction along Cyprus Arc and the collision of Arabian Plate along Bitlis Suture. On the other hand, the shear wave splitting measurements which characterize the seismic anisotropy are very sparse in the region. The seismic data recorded by national seismic networks with a denser coverage provides a unique opportunity to analyze the effect of present slab geometry (slab tears, slab break-off...
