RISIntroducing of Echinoids of the Gurpi Formation, Seimareh Member, Ilam province, Iran
The Gurpi Formation in Zarin Abad section, south of Ilam, consist of 220m Marl with intercalations of Limy Marl with two formal members of Seimareh(Lopha) and Emam- Hasan
Late Santonian-Early Maastrichtian calcareous nannofossils from marly deposits near Kerman (Central Iran)
in the Kerman basin,
Central Iran. In most parts of Central Iran, the Upper
Cretaceous sequence is complete and continuous and is divided
into two groups: Cenomanian–Touronian flysch and
Campanian–Maastrichtian flysch. Flyschs...
Lithostratigraphic and Biostratigraphic studies of Neyzar Formation in Jalil- Abad section (northwest of Mashhad, Iran)
and Benthonic foraminifer have been reported.
Based on fossils identified especially, Siderolites calcitrapoides, Abathomphalus mayaroensis, Orbitoides apiculata, Orbitoides media, Maaastrichtian especially Late Maastrichtian age for Neyzar Formation...
Late Maastrichtian benthic foraminiferal response to palaeoenvironmental changes: a case study from the AbTalkh Formation, west of Kopeh-Dagh Basin, Iran
Benthic foraminiferal assemblages from Maastrichtian strata, Gansserina gansseri-Abathamphalus mayaroensis Planktonic Foraminiferal Zone, of the AbTalkh Formation at Aitamir section (west of the Kopeh-Dagh basin) were investigated in order...
Significance of ichnofossils in high resolution sequence stratigraphy: Upper Maastrichtian, Kopeh- Dagh Basin, NE Iran
This study shows that ichonology can be used to refine sequence stratigraphy as well as to interpret the depositional environment of the Kalat Formation (Upper Maastrichtian) in the Central Kopeh- Dagh Basin (NE Iran), Dareh-Gaz section. Field...
The Campanian-Maastrichtian planktonic foraminifera of the Kopet-Dagh Basin (NE Iran): bioevents and biostratigraphy
Abstract
The Campanian-Maastrichtian Abtalkh Formation of the Kopet-Dagh Basin (NE Iran) has been studied for biostratigraphic purposes. The present study integrates results from three sections within the basin: Maraveh-Tapeh (Western Kopet...
Microbiostratigraphy and Depositional Environment of Kalat Formation based on Foraminifera in Kalat-Naderi section (Northeast of Mashhad, Iran)
Microbiostratigraphy and Depositional Environment of Kalat Formation based on Foraminifera in Kalat-Naderi section (Northeast of Mashhad, Iran)
Upper Maastrichtian depositional environments and sea-level history of the Kopet-Dagh Intracontinental Basin, Kalat Formation, NE Iran
Abstract The Kopet-Dagh Basin is located in northeastern Iran and southern Turkmenistan. The Late
Maastrichtian Kalat Formation caps the Cretaceous interval in this Basin. Based on eight measured stratigraphic sections, the depositional...

Biostratigraphy, microfacies and depositional environment of the Campanian-Lower Maastrichtian sequences in the Nasir Kandi area in southern part of the Moghan sedimentary basin, NW Iran
زیست چینه نگاری، ریزرخساره‌ها و محیط رسوبی توالی کاﻣﭘانین ـ مایستریشتین زیرین ناحیه نصیر کندی در بخش جنوبی حوضه رسوبی مغان، شمال غرب ایران
ردیف رسوبات کرتاسه بالایی در حوضه مغان از جمله توالی‌های چینه‌ای بااهمیت از دیدگاه اکتشاف ذخایر هیدروکربوری می‌باشند که به تازگی مورد توجه قرار گرفته‌اند. در این مطالعه 498 متر از این توالی که متشکل از سنگ آهک رس‌دار با ...
