Cretaceous pelagic red beds and black shales (Aptian-Santonian), NW Turkey: Global oceanic anoxic and oxic events Yılmaz, İsmail Ömer (2008-04-01) The study areas located near the towns of Goynok, Muclurnu and Nallihan in the central northwestern part of Turkey lie on the 'Sakarya Continent', which is one of the tectonic entities of the Cretaceous geology of Turkey. Measured stratigraphic sections comprise the Aptian pelagic carbonates and the overlying Albian-Coniacian turbiditic sequences, which are all capped by a Late Santonian red pelagic succession. Lower and Upper Aptian, Upper Albian and Cenomanian/Turonian marine black shales recognized in th...

Cretaceous and Triassic subduction-accretion, high-pressure-low-temperature metamorphism, and continental growth in the Central Pontides, Turkey Okay, A. I.; Tuysuz, O.; Satir, M.; Altıner, Sevinç; Altıner, Demir; Sherlock, S.; Eren, R. H. (2006-09-01) Biostratigraphic, isotopic, and petrologic data from the Central Pontides document major southward growth of the Eurasian continental crust by subduction-accretion during the Cretaceous and Triassic Periods. A major part of the accreted material is represented by a crustal slice, 75 km long and up to 11 km thick, consisting of metabasite, metaophiolite, and mica schist that represent underplated Tethyan oceanic crustal and mantle rocks. They were metamorphosed at 490 degrees C and 17 kbar in mid-Cretaceous ...
Cretaceous black shales (Oceanic Anoxic Events) in Turkey:collaboration of tectonics, sea level and oceanographic changes Yılmaz, İsmail Ömer (null; 2017-08-26) Cretaceous oceanic anoxic events are recorded as black shale deposits in Mid-Barremian, Aptian, Cenomanian/Turonian stages in different basins in Turkey. The Mid-Barremian black shales (MBE) have been recorded within a turbidite succession in a deep marine setting in central Sakarya zone of Pontides (YILMAZ et al., 2012). 2 ‰ shifts in the carbon isotope curve are recorded in parallel with European basins, but with low TOC values. The Aptian black shales (OAE1a) are recorded in pelagic carbonate slope envir...
Cretaceous Evolution of the Central Asian Proto-Paratethys Sea: Tectonic, Eustatic, and Climatic Controls Kaya, Mustafa Yücel; Dupont-Nivet, Guillaume; Proust, Jean-Noël; Roperch, Pierrick; Meijer, Niels; Frieling, Joost; Fioroni, Chiara; Altıner, Sevinç; Stoica, Marius; Aminov, Jovid; Mamtimin, Mehmut; Guo, Zhaojie (American Geophysical Union (AGU), 2020-09-01) The timing and mechanisms of the Cretaceous sea incursions into Central Asia are still poorly constrained. We provide a new chronostratigraphic framework based on biostratigraphy and magnetostratigraphy together with detailed paleoenvironmental analyses of Cretaceous records of the proto‐Paratethys Sea fluctuations in the Tajik and Tarim basins. The Early Cretaceous marine incursion in the western Tajik Basin was followed by major marine incursions during the Cenomanian (ca. 100 Ma) and Santonian (ca. 86 Ma...
