Abstract
A calcareous nannofossils biostratigraphic study has been carried out on the chalky limestones which are located in South Gorgan, North of Iran. The study is aimed at establishing the age and nannofossils biozonations of the well. The samples were prepared using smear slide technique. Thirty seven calcareous nannofossils species were identified and used to make biostratigraphic zonations and dating of the strata. The distribution of the calcareous nannofossils enabled the establishment of five zones of Quadrum trifidum (CC22), Tranolithus phacelosus (CC23), Reinhardtites levis (CC24), Arkhangelskeilla cymbiformis (CC25) and Nephrolithus frequens (CC26) belonging to Late Late Campanian – Late Late Maastrichtian following standard zonation schemes of previous workers. The zones were based on the first and last occurrences of marker species.
