Sanganeh Formation was introduced as one of the Early Cretaceous Formations in the Kopet-Dagh basin. By using polarized microscope, 15 genera and 36 species were identified at Mozduran locality. According to stratigraphic distribution of calcareous nannoplanktons of the studied sections, the first occurrence of index species and fossil assemblages, 4 biozones of Sissingh biozonation (1977) are suggested which are coincide with biozones of CC8- CC11. Based on the mentioned biozones, the Albian/ Early- Middle Turonian age is proposed for the studied section.
