Biostratigraphy of the Baghamshah Formation based on calcareous nannofossils in Baghdadeh section (East margin of Lut Block)
In the present study, Baghamshah Formation in Baghdadeh section located in the eastern margin of Lut Block to biostratigraphic studies based on calcareous nannofossils was sampled. Thickness of Baghamshah Formation in this section is 253m and mainly contains of shale and marl. According to the paleontological studies, 43 nannofossil species belong to 20 genera with well to moderate preservation in Baghdadeh section were identified and photographed. Based on the index calcareous nannofossils and assemblages species, CC1-CC5 biozones of Sissingh (1977) were determined. According to determined biozones, age of the Baghamshah Formation in Baghdadeh section Early Berriasian to Early Barremian was suggested.
