On the nature of the Cimmerian Continent Şengör, Ali Mehmet Celal; Altıner, Demir; Zabcı, Cengiz; Sunal, Gürsel; Lom, Nalan; Aylan, Eşref; Öner, Tayfun (2023-12-01) The Cimmerian Continent is the narrow continental strip that rifted from the northeastern Gondwana-Land margin mostly during the Permian between the present-day Balkan regions and Indonesia and collided with the Laurasian ...
Late Cretaceous arc magmatism in the Western Pontides (Turkey) - temporal and chemical changes Sağlam, Ezgi; Duzman, Turgut; Ay, Cemre; Okay, Aral; Topuz, Gültekin; Sunal, Gürsel; Özcan, Ercan; Altıner, Demir; Hakyemez, Aynur; Wang, Jia-Min; Kylander-Clark, Andrew R. C. (2023-06-01) During the Late Cretaceous, a magmatic arc extended from the Lesser Caucasus through the northern margin of the Pontides into Srednogorie, Timok, Banat, and Apuseni (ABTS) in the Balkans for a distance of 2700 km. We studi...
Prolonged and gradual recovery of metazoan-algal reefs following the end-Permian mass extinction Kelley, Brian M.; Yu, Meiyi; Lehrmann, Daniel J.; Altıner, Demir; Payne, Jonathan L. (2023-01-01) The tempo of biotic recovery following extinction reflects the time scales of evolutionary processes and the long-term consequences of degraded ecosystems, but recovery patterns are poorly resolved. In this study, we inves...
Calibrating the Late Jurassic–Early Cretaceous shallow and deep marine bioevents by quantitative biostratigraphy: A synthesis from the Pontides Carbonate Platform (Turkey) Atasoy, Serdar Görkem; Altıner, Demir; Altıner, Sevinç (2022-08-01) © 2022 Elsevier B.V.The Late Jurassic–Early Cretaceous is an interval of unstandardized stages and includes the only Mesozoic system boundary without a Global Boundary Stratotype Section and Point – the Jurassic/Cretaceous...
Mezozoyik'te Standardize Edilmemiş Son Sistem Sınırı Olarak Kalan Jura – Kretase Geçişi Boyunca Sığ ve Derin Denizel Biyo-olaylarının Sayısal Biyostratigrafik Yöntemler İle Kalibrasyonu: Pontid Karbonat Platformundan Bir Sentez Atasoy, Serdar Görkem; Altıner, Demir; Altıner, Sevinç (2022-05-09) Geç Jura-Erken Kretase aralığı standardize edilmemiş birçok katı kapsamakta olup, Mezozoyik'te GSSP ile tanımlanmamış tek sistem sınırı olan Jura/Kretase (J/K) sınırını içermektedir. Tetis kuşağındaki derin denizel devamlı...
Duration and Intensity of End-Permian Marine Anoxia Pimentel-Galvan, Michael; Lau, Kimberly V.; Maher, Katharine; Mukerji, Tapan; Lehrmann, Daniel J.; Altıner, Demir; Payne, Jonathan L. (2022-01-01) Ocean anoxia was an important kill mechanism in the end-Permian mass extinction and uranium isotope data are among the most powerful tools for quantifying the global extent and duration of ocean deoxygenation due to the de...
Triassic Foraminifera from the Great Bank of Guizhou, Nanpanjiang Basin, south China: taxonomic account, biostratigraphy, and implications for recovery from end-Permian mass extinction Altıner, Demir; Lehrmann, Daniel J.; Altıner, Sevinç; Summers, Mindi M.; Yu, Meiyi (2021-12-01) Foraminifera are important components of tropical marine benthic ecosystems and their recovery pattern from the end-Permian mass extinction can yield insights into the Mesozoic history of this group. Here we report the cal...
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 (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...
