| In this resaerch for introduction of late Cretaceous calcareous nannofossils in Middle Tethys Ocean, Azizabad stratigraphic section of the the Farokhi Formation in Central Iran has been selected. Thickness of formation in this section is 233 meters and consists of marl and marly limestone. In this research 42 species belong to 25 genera of nannofossils with good preservation were identified. Based on the index nannofossilspecies and nannofossil assemblages, CC21-CC26 for Farokhi Formation determined. Deterrmined biozones indicate early late Campanian – late late Maastrichtian age for Farokhi Formation in Azizabad section. |
