Calcareous nannofossils are one group of microfossils that use in biostratigraphy studies since the 1950’s and 1960’s. Recently, because of the potential of nannofossil species for age determination, several authors use this fossil-group in the study of Cenozoic sediments and rocks. Here, we present a nannofossil biozonation based on biostratigraphic information from the Sabzevaran section […]
