Abstract

In this research, biostratigraphy of a stratigraphic section in the east Afzalabad section in Lut Block (part of flyschoid basin in East Iran) were investigated based on calcareous nannofossils. Nineteen genera and 52 species of calcareous nannofossils were identified based on which the studied sequence confirm with NN8- NN10 biozones of Martini (1971) indicating a middle Miocene to late Miocene age.
