Popis:	A total of 165 samples were collected from the Qom Formation investigated in a stratigraphic section north of Deh Namak, in Central Iran. From these, 35 genera and 47 species of benthic foraminifera were identified. The age of the studied section is Early Miocene (Aquitanian to Early Burdigalian) based on the occurrence of Borelis melo curdica , Meandropsina anahensis , Meandropsina iranica , Elphidium sp. 14, Peneroplis farsensis , and Triloculina tricarinata . The thickness of the Qom Formation is 401 m of which 161.2 m is early Burdigalian in age. Foraminiferal assemblages in the Deh Namak section are referable to the Borelis melo group- Meandropsina iranica Assemblage Zone and Miogypsinoides - Archaias -Valvulinid Assemblage Zone of [Adams, T.D., Bourgeois, F., 1967.
