the sarcheshmeh formation is a shaly sequence of lower cretaceous age (aptian) which is deposited in koppeh-dagh sedimentary basin and conformably overlies and underlies the tirgan and sanghaneh formations respectively in the toos well # 1. lithologically, this formation has a thickness of 177m and consists mainly of marl, shale and shaly limestone. palynological studies resulted in identificat...

A totall of 500 Early Permian samples from the Chal-i-Sheh Formation in the Zagros Basin were examined palynollogically in order to determine the stratigraphical age of the formation and to assess the palaeogeopaphicd relatianships of this basin to the Southern and Northern Hemispheres during the Early Permian. Fifty-eight taxa were recorded including 46 pollen, 10 spore and 2 acritarch spe...

The Upper Cretaceous strata were studied in a composite stratigraphic section named here Padeha-Baghak section in east of Koppeh-Dagh basin, north east of Iran. In this study, palynostratigraphy, palynofacies and depositional environment history of Abderaz Formation were integrated with sequence stratigraphy. Determination of sea level history and sequence units of the Abderaz Formation using s...

reasonably diverse and fairly preserved palynoflora, dominated by land-derived palynomorphs (miospores) in association with minor marine entities, such as dinoflagellate cysts, foraminiferal test linings, and acritarchs, occur in surface samples of the hojedk formation, at the eshkeli stratigraphic section, north of kerman. spores with radiosymmetrical symmetry (trilete spores), bisaccate and m...
