Planktonic foraminiferal biostratigraphy and microfacies analysis of the cenomanian-campanian succession in the Haymana-Polatlı Basin (Ankara, Turkey)
Sarıaslan, Nisan; Altıner, Sevinç; Department of Geological Engineering (2017)
In order to establish the planktonic foraminiferal biostratigraphy of the Cenomanian- Campanian deposits in the Haymana-Polatlı Basin, a stratigraphic section of 93.5 meters was measured and 75 samples were collected. The stratigraphic section starts with limestones containing late Cenomanian rotaliporid and dicarinellid species and continues with early-middle Turonian aged clayey limestones with sporadic shale beds. These units are overlain by red colored Santonian limestones and shales containing abundant...
Planktonic foraminiferal biostratigraphy, sequence stratigraphy and foraminiferal response to sedimentary cyclicity in the upper cretaceous-paleocene of the Haymana basin (Central Anatolia, Turkey)
Amirov, Elnur; Altıner, Sevinç; Department of Geological Engineering (2008)
The aim of this study is to establish the planktonic foraminiferal biozonation, to construct the sequence stratigraphical framework and to determine the foraminiferal response to sedimentary cyclicity in the sedimentary sequence spanning Upper Cretaceous-Paleocene in the Haymana basin (Central Anatolia, Turkey). In order to achieve this study, the stratigraphic section was measured from sedimentary sequence of the Haymana, Beyobası and Yeşilyurt formations. The sedimentary sequence is mainly characterized b...
Planktonic foraminiferal biostratigraphy of the paleocene-eocene sequences in the western and central black sea region, Turkey
Güray, Alev; Altıner, Sevinç; Department of Geological Engineering (2014)
The Paleocene-Eocene sequences are widely distributed around onshore and offshore Black Sea. When the previous studies in the Turkish coasts of the Black Sea are considered, the deficiency of a detailed biostratigraphical framework attracts the attention. The taxonomy of the planktonic foraminifera and the benthic foraminifera assemblages are important for the establishment of the new biostratigraphical frame in the Paleocene-Eocene sequences of the Western and Central Black Sea regions. The Paleocene-Eocen...

The Cretaceous-Paleogene (K/Pg) boundary in the Haymana Basin, Central Anatolia, Turkey, was delineated using planktonic foraminiferal biostratigraphy, microfacies analysis, and sequence stratigraphy. An similar to 29 m outcrop consisting of limestone and marl was measured, and four planktonic foraminiferal biozones were identified spanning the boundary. Planktonic foraminiferal extinction across the K/Pg boundary was catastrophic and abrupt. The extinction level is overlain by a unit (Zone P0) showing an i...
Planktonic foraminiferal diversity and abundance changes across cretaceous-paleogene boundary beds in the Haymana basin and new observations on the extinction horizon
Karabeyoğlu, Ali Uygar; Altıner, Sevinç; Altıner, Demir; Department of Geological Engineering (2017)
Abundance and diversity patterns in planktonic foraminifera are important for paleoenvironmental and paleoclimatic interpretations before and after the CretaceousPaleogene mass extinction. A 14,53 m thick section was measured crossing the boundary between the Haymana Formation and the Yeşilyurt Formation in the northern part of the Haymana Basin. In the last 3.75 meters of the Maastrichtian below the K-Pg boundary, a series of quantitative analyses were carried out on planktonic foraminifera found above 63 ...
