Paleocene and  Lower Eocene deposits in SW Iran are known as Pabdeh formation.Pabdeh formation is one of the most important lithostratigraphy unit as source rock has been deposited in Zagros basin over an extremely long period in time. The area under research is the Ghachsaran 55 subsurface Section located  from the Ghachsaran oil field in Dezful embeyment in zagros fold zone. The Lower boundry...

Planktonic foraminifera and major palynomorph groups (i.e. terrestrial, marine, and amorphous organic matter) of the Campanian-Selandian strata of the Gurpi Formation were studied to evaluate the changes in the Zagros paleobasin in southwestern Iran. Planktonic foraminifera were categorized into four morphotypes according to their paleodepth, extending from Morphotype 1, comprising surface gene...

ghalajeh synclinal is extended on the south of kermanshah province from northwest to southeast. considering the permanent tectonic movements in quaternary and current age in studied region, the alluvial fans of the region is a good reason for evaluation of such movements. the morphology and morphometry properties of alluvial fans are severely under the effect of the tectonic activities. the aim...

The studied area includes Sulaimani, Erbil and Dohuk Governorates where Cretaceous rocks are well exposed in the High Folded Zone of North and Northeastern Iraq. This area is part of the northwestern boundary of Arabian platform near to Iranian border. In these governorates, the study tries to clarify the relations between deep and shallow stratigraphic units (formation or facies) during Cretac...

the gurpi formation, at the type section (nw of masjed-soleiman) and in sabze-kuh (sw of borujen) are lithologically subdivided into 8 and 11 units, respectively. the study of planktonic foraminifera resulted in recognition of 7 biozones in lali area and 4 biozones in sabzeh-kuh area. these biozones are compared to the most standard biozones defined in tethysian domain. biozones i (globotruncan...

Calcareous nannofossil biostratigraphy reveals a continuous depositional record through the Upper Cretaceous‒Paleocene succession in Zagros Basin; southwest Iran (southeastern part of Neo-Tethys), especially Cretaceous‒Paleogene and Danian‒Selandian boundaries. The upper Gurpi Formation lower Pabdeh were investigated. assemblages from these formations are characterized by abundant, diverse mode...
