The deposition of Jurassic-Lower Cretaceous carbonates in the Pontides was controlled mainly by the evolution of an Atlantic-type continental margin in the Tethys. The study of several stratigraphic sections from allochthonous slices and blocks of the North Anatolian Ophiolitic Melange provided insight into the Middle Jurassic-Early Cretaceous paleogeographic evolution of the Central Pontide Belt. The Callovian-Aptian successions span the Globuligerina gr. oxfordiana, Clypeina jurassica (equivalent of the Tubiphytes morronensis zone), Protopeneroplis ultragranulata (with the Haplophragmoides joukowskyi subzone), Montsalevia salevensis, Hedbergella delrioensis - Hedbergella planispira - Larpoldina - Globigerinelloides and Globigerinelloides algerianus biozones.

Late Cretaceous-Eocene Geological Evolution of the Pontides Based on New Stratigraphic and Palaeontologic Data Between the Black Sea Coast and Bursa (NW Turkey) Ozcan, Zahide; Okay, Aral; Özcan, Ercan; Hakyemez, Aynur; Altıner, Sevinç (2012-01-01) The Late Cretaceous-Eocene geological evolution of northwest Turkey between the Black Sea and Bursa was studied through detailed biostratigraphic characterization of eleven stratigraphic sections. The Upper Cretaceous sequence in the region starts with a major marine transgression and lies unconformably on a basement of Palaeozoic and Triassic rocks in the north (Istanbul-type basement) and on metamorphic rocks and Jurassic sedimentary rocks in the south (Sakarya-type basement). Four megasequences have been...
An example of an accretionary fore-arc basın from Northern Central Anatolia and its implicaiıons for the history of subduction of neo-tethys in Turkey KOCYIGIT, A (1991-01-01) Deformed sedimentary sequences of Late Cretaceous-middle Eocene age located between the Sakarya continent and the Anatolian Complex have been interpreted as the fill of a forearc basin. The history and structure of this basin are critical for understanding the evolution of the Neo-Tethyan subduction in the Middle East. I test and elaborate upon this interpretation on the basis of three basic outcrop areas of Upper Cretaceous-lower Tertiary sedimentary sequences confined to a northeast-southwest-trending b...
Late Cretaceous extensional denudation along a marble detachment fault zone in the Kirsehir massif near Kaman, central Turkey Lefebvre, Come; Barnhoorn, Auke; van Hinsbergen, Douwe J. J.; Kaymakcı, Nuretdin; Vissers, Reinoud L. M. (2011-08-01) In the Central Anatolian Crystalline Complex (CACC), 100 km scale metamorphic domains were exhumed in a context of north-south plate convergence during late Cretaceous to Cenozoic times. The timing, kinematics and mechanisms of exhumation have been the focus of previous studies in the southern Nigde Massif. In this study, we investigate the unexplored northern area regarding the tectonic features preserved on the edges of the Kirsehir Massif, based on detailed field-mapping in the Kaman area where high-grad...
Stratigraphical, sedimentological, geochemical and cyclostratigraphical analyses of upper cretaceous (upper santonian- campanian) pelagic successions of Haymana and Mudurnu-Göynük basins of the Sakarya continent, Turkey Afridi, Bakht Zamir; Yılmaz, İsmail Ömer; Department of Geological Engineering (2014) The Upper Cretaceous (Upper Santonian-Campanian) successions were measured from two different basins of Turkey, Haymana basin and Mudurnu-Göynük basin. The measured Alagöz and Göynük sections are dominantly composed of red marly beds and fine grained siliciclastic green-gray beds with occasional interruption of fine grained turbiditic bedding. A variety of lithofacies are identified in the studied sections, including radiolarian packstone, silty marls, marls, mudstone, claystone, siltstone and fine grained ...
Middle-late Asselian (Early Permian) fusulinid fauna from the post-Variscan cover in NW Anatolia (Turkey): Biostratigraphy and geological implications Okuyucu, Cengiz; Göncüoğlu, Mehmet Cemal (2010-03-01) The earliest autochthonous cover of the Variscan basement of the Sakarya Composite Terrane (SCT) in NW Anatolia is represented by basal conglomerates and limestones. The microfacies types of the limestones in ascending order are: (1) bioelastic grainstone/packstone, (2) fusulinid grainstone/packstone, (3) smaller foraminiferal grainstone/packstone, (4) Anthracoporella (dasycladale) grainstone/packstone. and (5) wackestones. Twenty-three species assignable to 15 genera of fusulinids were recovered from the s...
