RISA Cenomanian-Turonian drowning unconformity on the eastern part of Kopet-Dagh basin, NE Iran
A Cenomanian-Turonian interval in the Mozduran pass section, eastern part of Kopet-Dagh basin
(NE of Iran), was measured and studied in order to interpret the biostratigraphy and paleoecology (based on distribution of planktonic foraminifera...
Investigating the paleoecological characteristics of Abtalkh Formation at Bahadorkhan Section (Central Kopet-Dagh) based on planktonic and benthic foraminifera
Study of a late Late Santonian to Late Campanian hemipelagic succession from Abtalkh Formation at the Bahadorkhan section (Central Kopet-Dagh) enabled us to verify paleoecology changes based on planktonic and benthic foraminifera assemblage...
Biostratigraphy of the Abderaz Formation based on heterohelicids, at six stratigraphical sections in east and center of the Kopeh-Dagh sedimentary basin, northeastern of Iran
from a sequence with 2800 meter thickness. Also 4 genera and 17 species of biserial planktonic foraminifera have been identified and two biozones and two subzones recognized.
Based on obtained data, the age of Early Turonian-Earliest Campanian...
Planktonic Foraminiferal bioevents in the ATuronian/ Coniacian boundary interval in the Abderaz Formation at type section, Kopet-Dagh basin, Iran
The interval studied comprises a 50-m- thick section of upper Turonian and Lower Coniacian srata.
Age determination of Abderaz Formation based on Foraminifera in Shurab section-east Kopet- Dagh basin, NE Iran
The Kopet- Dagh form a linear intracontinental fold and thrust belt NW-SE between the stable Tuekmenistan platform and central Iran in NE Iran
Lithostratigraphic and Biostratigraphic studies of Neyzar Formation in Jalil- Abad section (northwest of Mashhad, Iran)
Formation with Abtalkh Formation is conformable and the upper contact this formation with Kalat Formation is Disconformable (as a paleosol). At the first time, on the base of Micropaleontological studies, 33 species belonging to 26 genera of Planktonic...
Ultraviolet radiation enhances Arctic net plankton community production
Integrated biostratigraphy and stage boundaries of the Abderaz Formation, east of the Kopeh-Dagh sedimentary basin, NE Iran
. The Abderaz Formation was sampled at the following four sections: the Qarehso
section, the Abderaz village section, the Muzduran section and the Shorab section. The Qarehso section is approximately 540 m thick and consists of 77 planktonic foraminifera...
Planktonic foraminiferal turnover across the Cenomanian –Turonian boundary (OAE2) in the northeast of the Tethys realm, Kopet-Dagh Basin
Two Late Cenomanian – Early Turonian (C–T) intervals of the eastern part of the Kopet-Dagh basin, NE Iran have been investigated to evaluate the response of planktonic foraminifera to the geological event OAE2. The Gharesu and Taherabad sections...
Planktonic foraminifera and dinoflagellate cysts from the Upper Cretaceous Abderaz Formation in the Koppeh-Dagh Basin, NE Iran
Assemblages of planktonic foraminifera and dinoflagellate cysts were studied from the 359 m thick Padeha-Baghak composite section of the Abderaz Formation, eastern Koppeh-Dagh Basin, NE Iran. The formation consists mainly of light grey shales...
