Neogene Nannofossils and Biostratigraphy of the Sadaf-l Well, Offshore Pakistan
The biostratigraphy of Sadaf-l well has been established on the basis of nannofossils. The rock samples between the interval 2640-13050 ft are dated from Early Pliocene to Early Miocene. Fifty-six species of nannofossils are identified, and with the help of the index species and some additional assemblage, Neogene nannofossil zonal boundaries are marked. Five important species are measured and their taxonomy is described.
