Paleoclimate Reconstruction during Pabdeh, Gurpi, Kazhdumi and Gadvan Formations (Cretaceous-Tertiary) Based on Clay Mineral Distribution
Paleoclimate was reconstructed by the clay mineral assemblages of shale units of Pabdeh (PaleoceneOligocene), Gurpi (Upper Cretaceous), Kazhdumi (Albian-Cenomanian) and Gadvan (Aptian-Neocomian) formations in the Bangestan anticline. To compare with clay minerals assemblages in these formations, selected samples also taken from available formations in drilled wells in Ahvaz, Marun, Karanj, and ...
متن کاملmicrobiostratigraphy of asmari formation in robat namaki section, zagros basin
asmari formation was deposited in the foreland zagros basin (southwest iran). in this research, biostratigraphy related to the asmari formation in north of khorram abad, robat namaki section, is discussed. in the studied stratigraphic section, the asmari formation overlies the shahbazan formation and underlies gachsaran formation and consists of cream to gray medium to thick limestone and marl....
متن کاملMicrofacies, geochemical characters and possible mechanism of rhythmic deposition of the Pabdeh Formation in SE Ilam (SW Iran)
Rhythmical alternations between limestone and marls characterize the Pabdeh Formation, southwestern Iran. Three intervals of these rhythmites were studied using sedimentary, petrography and geochemical parameters analysis, to unravel the possible mechanisms responsible for the origin of these rhythmites. The microfacies analysis reflects calm deep-water sedimentation that were interrupted by sp...
متن کاملCalcareous nannofossils biostratigraphy of the Campanian-Danian interval, Gurpi Formation in the Zagros Basin, SouthWest Iran
This study presents calcareous nannofossils biostratigraphy of the Campanian‒Danian interval at the Gurpi Formation in the southwest of Ilam Province, in the Zagros Basin. The studied sequence of the Gurpi Formation mainly consists of marly shale and limestones. The thickness of Gurpi Formation was measured as approximately 230 m. Forty-five species belonging to twenty-eight genera were recorde...
متن کاملMicrobiostratigraphy of Middle Eocene ShahbazanFormation at the southeastern flank of Chenar Anticline,Lurestan Basin, Sw Iran
In this research, biostratigraphy related to the carbonate succession of the Shahbazan Formation at the southeastern flank of Chenar anticline, Lurestan Basin, is discussed. A study of large benthic foraminifera from the 294 mthick Shahbazan Formation led to the identification of two Middle Eocene biozones: Somalina sp. Zone, Nummulites-Alveolina Assemblage Zone. The age of the Shahbazan Format...
