Abstract

 In this study, a core with 10.5 m lenght and in shallow water in Bandar Abbas (Shahid Rajaee Port area) was studied based on calcareous nannoplankton. In this study, 52 samples of sediment cores were taken and prepared. Most species were photographed by light microscope. For the first time 21 genera and 35 species introduced in this area. In the core mentioned Gephyrocapsa oceanica and Emiliania huxleyi are the dominant taxa, based on the abundant presence of these species can be concluded that the Persian Gulf basin is a marginal sea in the lower latitudes and shallow areas have been formed and in this area productivity of nannoplankton is high.
