The first report of silicified ostracodes of Thuringian Ecotype (sensu BECKER) from Early Devonian (Emsian) limestones of the Pelitli and Kartal formations in NW Anatolia (Yakacik area, Istanbul, Turkey) is presented. The poorly preserved faunas of only nine taxa indicate faunal relations of the Istanbul Terrane especially to Thuringia (Germany) and Morocco during the Emsian.


Upper Cretaceous Radiolarian ages from an arc-back-arc within the Yuksekova Complex in the southern Neotethys melange, SE Turkey

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...
Late Paleocene Orthophragminae (foraminfera) from the Haymana-Polatli Basin, central Turkey) and description of a new taxon, Orbitoclypeus haymanaensis
Özcan, Ercan; Sirel, Ercüment; Altıner, Sevinç; Çolakoğlu, Sinan (GeoScienceWorld, 2001-12-01)
A transgressive shallow-marine succession suggested as a reference-section for early Thanetian by the 'Early Paleogene working group' (IGCP 286) was studied for its orthophragminid foraminifera from Haymana-Polath Basin in central Anatolia. Orthophragminae, closely associated with Assilina yvettae and Operculina heberti, have been identified in a friable clastic-carbonate sequence which contains Glomalveolina in its different horizons. Basinal sediments with planktonic taxa overlie the shallow-water deposit...
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...
Early Cambrian trace fossils at the northern margin of the Arabian Plate; Telbesmi Formation, Turkey
Demircan, Huriye; GÜRSU, SEMİH; Göncüoğlu, Mehmet Cemal (2018-01-01)
The Telbesmi Formation, at the northern margin of the Arabian Plate, Turkey, is composed of alternating dark-brown, pinky-brown fluvial arkosic sandstone/mudstones with thin-bedded cherry limestones and channel conglomerates. The formation contains rare and poorly diversified trace fossils. The siltstone/sandstone beds of levels 1 and 2 of the formation yielded, however, a moderately diverse assemblage composed of: Cochlichnus isp., Palaeophycus isp., Planolites beverleyensis, Teichichnus isp. and ?Treptich...
The upper Coniacian to upper Santonian drowned Arabian carbonate platform, the Mardin-Mazidag area, SE Turkey: Sedimentological, stratigraphic, and ichthyofaunal records
Yılmaz, İsmail Ömer; Hosgor, Izzet; Wagreich, Michael; Rebman, Katherine; Murray, Alison M. (2018-04-01)
A measured stratigraphic section including the upper Coniacian - upper Santonian interval in the Mardin-Mazidag area in Southeastern Turkey lies on the Arabian Platform and documents the drowning of the Arabian platform. The studied succession transgressively overlies the exposed carbonate platform and exhibits a relatively condensed sequence characterized by presence of fish remains, phosphate nodules, oncoids, phosphatic fragments, glauconites and planktonic foraminifera. Calcareous nanno-fossils attest a...
