Abstract

Paleogene deposits crop out in south of Binalood structural zone, northeast of Iran. An outcrop in east of Ghalehvazir village 45 kilometers to the south east of Neyshabour with an age of Eocene-Oligocene containing continental red beds has been measured. The sequence overlain paraconformly the Eocene marine marls and gypsiferous marls. Twenty-four samples were taken for Nannostratigraphy of the section. Samples were all prepared using smear slides technique. Twenty-two species belong to 10 genera were identified. Based on the assemblage recovered, an age of middle Eocene (late Lutetian) was confirmed for the upper part of Eocene marine sediments
