Within the framework of an integrated stratigraphy, a detailed biostratigraphic study of Late Jurassic-Early Cretaceous (Tithonian-Valanginian) calcareous nannofossils was carried out in north-west Anatolia, Turkey.

Rapid cooling history of a Neotethyan ophiolite: Evidence for contemporaneous subduction initiation and metamorphic sole formation
PARLAK, OSMAN; Dunkl, Istvan; KARAOĞLAN, FATİH; Kusky, Timothy M.; Zhang, Chao; Wang, Lu; Koepke, Juergen; Billor, Zeki; Hames, Willis E.; ŞİMŞEK, EMRAH; Simsek, Gokce; ŞİMŞEK, TUĞÇE; Ozturk, Selena Ezgi (Geological Society of America, 2019-11-01)
The Beywhir-Hoyran Nappes, including Mesozoic carbonate platform rocks, deepsea sediments, and ophiolite-related units, crop out extensively on the western limb of the Isparta Angle in the Central Taurides, Turkey. The ophiolite-related rocks are represented by variably serpentinized harzburgitic mantle tectonites, tectonically underlain by a subophiolitic metamorphic sole and melange. The harzburgitic mantle tectonites and metamorphic sole are intruded by undeformed isolated dikes. Protoliths of the metamo...
Paleogene evolution and demise of the proto-Paratethys Sea in Central Asia (Tarim and Tajik basins): Role of intensified tectonic activity at ca. 41 Ma
Kaya, Mustafa Yücel; Dupont-Nivet, Guillaume; Proust, Jeannoel; Roperch, Pierrick; Bougeois, Laurie; Meijer, Niels; Frieling, Joost; Fioroni, Chiara; Altıner, Sevinç; Vardar, Ezgi; Barbolini, Natasha; Stoica, Marius; Aminov, Jovid; Mamtimin, Mehmut; Guo Zhaojie, Guo Zhaojie (Wiley, 2019-06-01)
The proto-Paratethys Sea covered a vast area extending from the Mediterranean Tethys to the Tarim Basin in western China during Cretaceous and early Paleogene. Climate modelling and proxy studies suggest that Asian aridification has been governed by westerly moisture modulated by fluctuations of the proto-Paratethys Sea. Transgressive and regressive episodes of the proto-Paratethys Sea have been previously recognized but their timing, extent and depositional environments remain poorly constrained. This hamp...
Use of sedimentary structures in the recognition of sequence boundaries in Upper Jurassic-Upper Cretaceous peritidal carbonates of the Western Taurides, Turkey
Yılmaz, İsmail Ömer; Altıner, Demir (Informa UK Limited, 2001-08-01)
Subtidal, intertidal, and supratidal carbonate facies are recognized in the Upper Jurassic (Kimmeridgian)-Upper Cretaceous (Cenomanian) peritidal carbonates of the Fele area (Western Taurides, Turkey). Vertical stacking patterns of these facies are of a cyclical character, shallowing upward is the trend of the cyclicity in these carbonate facies. In-situ karstic breccias, collapse breccias, caliche (laminar calcrete), "Microcodium" accretion, and root casts are structures commonly indicative of third-order ...
Tectonic evolution of the Gediz Graben: field evidence for an episodic, two-stage extension in western Turkey
Bozkurt, Erdin (Cambridge University Press (CUP), 2004-01-01)
Western Turkey is one of the most spectacular regions of widespread active continental extension in the world. The most prominent structures of this region are E-W-trending grabens (e.g. Gediz and Buyuk Menderes grabens) and intervening horsts, exposing the Menderes Massif. This paper documents the result of a recent field campaign (field geological mapping and structural analysis) along the southern margin of the modern Gediz Graben of Pliocene (similar to 5 Ma) age. This work provides field evidence that ...
Sarackoy Volcanic Suite: implications for the subductional phase of arc evolution in the Galatean Arc Complex, Ankara, Turkey
Kocyigit, A; Winchester, JA; Bozkurt, Erdin; Holland, G (Wiley, 2003-01-01)
A sequence of upper Campanian volcanic rocks, hitherto considered as part of the Miocene calc-alkaline Galatean volcanic sequence, crops out near Sarackoy, 40 km north of Ankara. These volcanic rocks, unconformably overlain by Eocene nummulitic limestones, comprise thin flows and volcaniclastic deposits. They can be divided compositionally into three distinct subunits: (i) basal massive trachyandesitic volcaniclastic rocks with a thin flow at the top, overlain by (ii) mixed volcaniclastic rocks and thin amy...
