Five different deformation phases have been recognized in the SE Anatolian orogen and the Arabian Platform based on palaeostress inversion studies using fault-slip data sets. The timing and duration of these phases are determined using various criteria including the age of the affected strata, syndepositional structures, cross-cutting structures and overprinting slickensides. The oldest deformation phase is characterized generally by NE-SW-directed extension. The extension is thought to have resulted from slab-roll back processes during the Maastrichtian to Middle Eocene interval (c. 60 Ma to 40-35 Ma). The second deformation phase is characterized by east-west to NW-SE-directed compression and thought to result from cessation of roll-back processes possibly due to subduction of younger oceanic crust or increase in the convergence rate between Africa and Eurasia during the post-Middle Eocene to Late Oligocene interval (c. 40-35 Ma to 25 Ma). The third deformation phase is characterized by east-west to NW-SE-directed extension possibly due to slab detachment that initiated in Iran and migrated westwards during the latest Oligocene to Middle Miocene period (25-11 Ma). The fourth deformation phase is characterized by approximately north-south-directed compression due to collision and further northwards indentation of Arabian Plate by the end of Middle Miocene (11-3.5 Ma). The fifth and present deformation phase is characterized by NE-SW compression which might result from tectonic re-organization in the region since the Middle Pliocene (c. 3.5 Ma to recent).

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 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...
Late Neogene oroclinal bending in the central Taurides: A record of terminal eastward subduction in southern Turkey? Koç, Ayten; van Hinsbergen, Douwe J. J.; Kaymakcı, Nuretdin; Langereis, Cornelis G. (2016-01-15) The Tauride fold-thrusts belt formed during similar to S-N convergence between Africa and Eurasia since Cretaceous time. The western end of the central Taurides strike NW-SE, highly obliquely to the overall convergence direction, and connect to the NE-SW Beydaglan-Lycian Nappe flank of the western Taurides, forming the so-called 'Isparta Angle'. In Neogene time, the western and central Taurides and the inner part of the Isparta Angle became overlain by Neogene sedimentary basins including Manavgat, Koprucay...
Upper Cretaceous planktonic foraminiferal biostratigraphy from NW Turkey calibration of the stratigraphic ranges of larger benthonic foraminifera Altıner, Sevinç (1999-01-01) Planktonic and larger benthonic foraminifers of the Upper Cretaceous (Santonian-Maastrichtian)-Lower Tertiary (Danian) rock units from north, northwest and central Anatolian fore-are basins have been investigated in order to improve the biostratigraphic resolution of this time interval. Total abundance and diversity of planktonic foraminifers vary from rare (the sequence from the Haymana region) to high (the sequences from the Cide, Caycuma, Hanonu and Yenikonak regions) and preservation is poor to moderate...
Late Permian (Tatarian) fluvio-lacustrine successions in NW Anatolia (Zonguldak Terrane, Turkey): palaeogeographic implications OKUYUCU, CENGİZ; Dimitrova, Tatyana K.; Göncüoğlu, Mehmet Cemal; Gedik, Ibrahim (2017-09-01) Late Permian fluvio-lacustrine successions of the Cakraz Formation in the Zonguldak Terrane between the regions of Akcakoca and Ereli were investigated in order to describe the litho- and biostratigraphic properties and explain the depositional environment. The studied succession with black, dark-grey to greenish-grey shales, siltstones and limestones is named the Alapl Member to distinguish it from the classical red clastic successions, which are tentatively named the Ereli Member of the Cakraz Formation. ...
