Implications of giant ooids for the carbonate chemistry of Early Triassic seawater
Li, Xiaowei; Trower, Elizabeth J.; Lehrmann, Daniel J.; Minzoni, Marcello; Kelley, Brian M.; Schaal, Ellen K.; Altıner, Demir; Yu, Meiyi; Payne, Jonathan L. (2021-02-01)
Lower Triassic limestones contain giant ooids (>2 mm) along with other precipitated carbonate textures more typical of Precambrian strata. These features appear to have resulted from changes in seawater chemistry associate...
PAYNITA PERMOTAURICA N. GEN., N. SP., AND THE OTHER DAGMARITIN FORAMINIFERA FROM THE CHANGHSINGIAN (PERMIAN) OF SOUTHERN TURKEY: REVIEW OF DAGMARITIN PHYLOGENY
Altıner, Demir; Altıner, Sevinç; Atasoy, Serdar Görkem; Sahin, Nazif (2021-01-01)
The name Paynita is proposed for a new dagmaritin genus from the upper Changhsingian (Permian) carbonates of the Southern Biofacies Belt in Turkey. Paynita permotaurica differs from its ancestor Paradagmarita monodi by a h...
Controls on carbonate platform architecture and reef recovery across the Palaeozoic to Mesozoic transition: A high-resolution analysis of the Great Bank of Guizhou
Kelley, Brian M.; Lehrmann, Daniel J.; Yu, Meiyi; Jost, Adam B.; Meyer, Katja M.; Lau, Kimberly; Altıner, Demir; Li, Xiaowei; Minzoni, Marcello; Schaal, Ellen K.; Payne, Jonathan L. (Wiley, 2020-10-01)
Carbonate platforms spanning intervals of global change provide an opportunity to identify causal links between the evolution of marine environment and depositional architecture. This study investigates the controls on pla...
Timing of depositional regime changes during the Late Cretaceous evolution of the Southern Pontides (Ankara, Central Anatolia, Turkey)
Sariaslan, Nisan; Altıner, Sevinç; Altıner, Demir (Elsevier BV, 2020-08-01)
During the Cretaceous, vast amounts of marine sediments were deposited along the south-facing active margin of the Eurasia. A stratigraphic section of 91 m was analyzed for planktonic foraminifera (75 samples), with the ai...
Faunal and environmental changes through the Cretaceous-Paleogene boundary (K-Pg) linked with Deccan Volcanism: evidence from the Neo-Tethys, Turkey
Karabeyoglu, Ali Uygar; Adatte, Thierry; Lorenzo, Valentin; Altıner, Sevinç; Altıner, Demir (2020-05-04)
Testing of Permian - Lower Triassic stratigraphic data in a half-graben/tilt-block system: evidence for the initial rifting phase in Antalya Nappes
Sahin, Nazif; Altıner, Demir (Canadian Science Publishing, 2019-11-01)
Testing of Middle Permian - Lower Triassic stratigraphic data from the Antalya Nappes in a half-graben/tilt-block system has revealed the presence of episodic rifting events separated by periods of tectonic quiescence. Fol...
The Cretaceous Mardin Group carbonates in southeast Turkey: Lithostratigraphy, foraminiferal biostratigraphy, microfacies and sequence stratigraphic evolution
Ozkan, Recep; Altıner, Demir (Elsevier BV, 2019-06-01)
The Mardin Group strata, as a product of the Cretaceous carbonate platform developed in the northern margin of the Arabian Platform, consists of a thick sedimentary sequence composed mostly of carbonates with subordinate c...
Major Late Cretaceous Mass Flows in Central Turkey Recording the Disruption of the Mesozoic Continental Margin
Okay, Aral; Altıner, Demir; Kylander-Clark, Andrew R. C. (American Geophysical Union (AGU), 2019-03-01)
The newly recognized Upper Cretaceous (similar to 87Ma) olistostrome belt in central Turkey west of Ankara extends for more than 112 km subparallel to the Izmir-Ankara suture with a width of 10 km. The Alacaatl Olistostrom...
Reconstruction of a Late Jurassic-Early Cretaceous carbonate platform margin with composite biostratigraphy and microfacies analysis (western Sakarya Zone, Turkey): Paleogeographic and tectonic implications
Atasoy, Serdar Görkem; Altıner, Demir; Okay, Aral (Elsevier BV, 2018-12-01)
During Late Jurassic-Early Cretaceous the Pontides were the site of a wide carbonate platform facing the Tethys ocean in the south. In the western Pontides the Upper Jurassic-Lower Cretaceous shallow marine carbonates abut...
Palinspastic Reconstruction Versus Cross-Section Balancing: How Complete Is the Central Taurides Fold-Thrust Belt (Turkey)?
McPhee, Peter J.; van Hinsbergen, Douwe J. J.; Maffione, Marco; Altıner, Demir (American Geophysical Union (AGU), 2018-11-01)
In many fold-thrust belts, cross section-derived shortening estimates are significantly lower than predicted based on plate convergence. This has led to controversial hypotheses that shortening may be largely underestimate...
