This thesis aims to conduct a thorough investigation on the Upper Jurassic – Lower Cretaceous İnaltı Formation which is a significant unit for the regional geology of Turkey. Conducted investigation involves micropaleontological and microfacies analyses integrated with stratigraphic interpretations. In the vicinity of Bürnük Village, a 395 m thick stratigraphic section, overlying the Bürnük Formation and underlying the Çağlayan Formation, was measured and 101 samples were collected. Biostratigraphic and chronostratigraphic works are based on the benthic foraminifera and encrusting sponge Calcistella jachenhausenensis. 44 species of foraminifera belonging to 35 genera, and 13 species of microencrusters were identified and 3 biozones were established. The biozones are Mesoendothyra izjumiana zone, Calcistella jachenhausenensis zone and Protopeneroplis ultragranulata zone in ascending order. Detailed microfacies analysis revealed the depositional history and carbonate platform evolution in the area. 15 microfacies types were determined in 5 different environments corresponding to slope, fore-reef, reef, back-reef and lagoonal environments on the carbonate platform. A vertical facies shift from platform margin (reef, fore-reef) - slope facies to inner platform (back reef-lagoonal) facies was observed in the Berriasian. Before cutting by Çağlayan clastics, again a facies shift towards the platform margin-slope facies took place in the studied part of the İnaltı carbonate platform. The studied section was correlated with some J-K boundary sections from different parts of the world. It is concluded that mentioning a general shallowing trend at/around the J-K boundary for all the correlated sections is not possible due to the preponderant local tectonics.

Foraminiferal and calpionellid biostratigraphy, microfacies analyses and tectonic implications of the upper jurassic – lower cretaceous carbonate platform to slope successions in sivrihisar region (Eskişehir, NW Turkey)
Atasoy, Serdar Görkem; Altıner, Demir; Department of Geological Engineering (2017)
This study focuses on the biostratigraphy, microfacies analyses and the tectonic interpretation of an Upper Jurassic – Lower Cretaceous carbonate succession widely exposed in a tectonic klippe of the Sakarya Zone (Pontides), north of Sivrihisar region (Eskişehir). For this purpose two stratigraphic sections were measured (925 m thick in total) along the carbonate rocks that crop out north of the Dümrek Village. According to the biozonation and the microfacies types, two coeval but dissimiliar depositional d...
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...
Microfacies analysis of upper devonian - lower carboniferous shallow water carbonates of the Yilanli formation in Zonguldak area, North Western, Turkey
Ahmed, Nouman; Yılmaz, İsmail Ömer; Department of Geological Engineering (2016)
The Yılanlı Formation of Upper Devonian to Lower Carboniferous succession of the Zonguldak region were measured from Gökgöl section near Zonguldak city, NW Turkey. The studied section dominantly consists of limestone of grey – dark grey color with thin to thick beds of black shale and claystone. A variety of lithofacies identified in the studied section including limestone, dolomite, shale, claystone and mudstone. Nine microfacies are identified as grainstone, packstone, wackstone, mudstone, bindstone, ruds...
CALCAREOUS NANNOFOSSILS FROM THE LATE JURASSIC EARLY CRETACEOUS OF NORTHWEST ANATOLIA, TURKEY
Altıner, Sevinç (Wiley, 1993-12-01)
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.
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...
