In the northwestern part of the Arabian Platform, the Adyaman district (SE Turkey) displays some Lower-Middle Cenomanian deep-marine sediments of the Derdere Formation. These sediments are yielding abundant echinodermal remains, among which some thecal and brachial plates are assignable to roveacrinids. Routine microfacies analysis of the Lower-Middle Cenomanian part of the Derdere Formation revealed unexpected early Cenomanian assemblages of roveacrinoidal ossicles, comparable with those formerly reported further south in the Cenomanian-Turonian of the Arabian Platform. For the first time, genuine and undisputable Roveacrinidae are illustrated for SE Turkey. Seven borehole sections were scrutinized in search of microcrinoidal sections, most especially within carbonate microfacies. Within the scope of better constraining the position of the Lower-Middle Cenomanian, we had been compiling the successive occurrence of respective identified roveacrinid remains. These roveacrinidal assemblages are consisting in: Roveacrinus communis Douglas (1908) (= R. derdereensis Farinacci & Manni); Roveacrinus cf. alatus Douglas (1908); Roveacrinus spinosus Peck (1943); Roveacrinus sp.; Roveacrinidae indet.; Applinocrinus sp.; and Saccocomidae indet. These specimens provide significant clues to constrain the palaeogeographic reconstruction of Tethyan seaways, and represent potential fossil index candidates for the Lower Cenomanian stratigraphy of the Adyaman district.

Tectonic evolution of the Cretaceous Ankara Ophiolitic Melange during the Late Cretaceous to pre-Miocene interval in Central Anatolia, Turkey Rojay, Fuat Bora (2013-04-01) The chaotic tectonic belt, which is distinguished in northern Anatolia, is called the - Ankara Accretionary Complex - in the Ankara region, central Anatolia. The belt is differentiated into three imbricated tectonic subbelts, namely, pre-Triassic metamorphics, Melange with calcareous blocks and Cretaceous melange with ophiolitic blocks (Ankara Ophiolitic Melange).
Silurian Graptolite, Conodont and Cryptospore Biostratigraphy of the Guluc Section in Eregli, Zonguldak Terrane, NW Anatolia, Turkey Sachanski, Valeri; Göncüoğlu, Mehmet Cemal; Lakova, Iskra; Boncheva, Iliana; Demiray, Gulnur Saydam (2012-01-01) The studied Guluc section of the Silurian Findikli Formation is situated on the western bank of Guluc Creek in Eregli, NW Anatolia, Turkey, in the eastern part of the Zonguldak Terrane. The Guluc section consists of 3 sedimentary packages: greenish grey limy siltstones, 5-7 m thick (1), overlain by an irregular alternation of black shales and clayey limestones, about 15 m thick (2), and a 6-7 m thick succession of mainly siltstones and sandy limestones (3). A combined biostratigraphy based upon graptolites,...
Cyclic Carbonate Facies Changes on the Middle to Upper Cenomanian Arabian Carbonate Platform, SE Turkey: An Approach for the Causes of Short- and Long-Term Sea-Level Change Yılmaz, İsmail Ömer; Mülayim, Oğuz; Sarı, Bilal; Simmons, Mike (2017-08-26) The studied Cenomanian shallow water platform carbonates of the Derdere Formation lies on the northern Arabian platform in Mardin area, SE Turkey. The sedimentology and cyclic nature of the facies along the studied composite sections have been analysed in terms of cyclostratigraphy. In the lower section, alternations of benthic foraminiferal-algal packstone/wackestone and bioturbated bioclastic wackstone/lime mudstone take place at the base of small scale cycles. Alternations of bivalve/ostracod wackestone/...
Tectono-Sedimentary evolution and geochronology of the Middle Miocene Altinapa Basin, and implications for the Late Cenozoic uplift history of the Taurides, southern Turkey KOÇ, AYTEN; Kaymakcı, Nuretdin; van Hinsbergen, Douwe J. J.; Kuiper, Klaudia F.; Vissers, Reinoud L. M. (2012-04-06) The Tauride range in southern Turkey is flanked and overlain by Neogene sedimentary basins. To the south and on top of the high range, these basins are mainly marine, whereas poorly studied intramontane basins dominated by continental deposits are exposed to the north. In this paper, we study the stratigraphy and structure of the continental Altinapa Basin, and provide Ar-40/Ar-39 geochronology for volcanic deposits in the stratigraphy. The stratigraphy can be subdivided into a Lower Group, displaying simil...
Analysis of the North Anatolian Shear Zone in Central Pontides (northern Turkey): Insight for geometries and kinematics of deformation structures in a transpressional zone Ellero, Alessandro; Ottria, Giuseppe; Marroni, Michele; Pandolfi, Luca; Göncüoğlu, Mehmet Cemal (2015-03-01) The western part of the North Anatolian Shear Zone at the southern boundary of the Central Pontides in Turkey, was investigated in the Kursunlu-Arac area by means of a geological-structural field study. In this area the North Anatolian Shear Zone results in a transpressional deformation zone that extends between two master faults striking parallel to the main shear direction. The main systems of structures identified in the deformation zone appear to be oriented parallel to the directions predicted by Riede...
