Palynomrphs extracted from rock samples of the Sanganeh Formation cropping out in the central Kopeh-Dagh Basin indicate a late Aptian-early Albian age for the formation. Eighty samples recovered from the shale and marl beds were processed and analysed for palynomorphs. Two palynological zones and tree types of Palynofacies have been identified. The Palynofacies and dinoflagellate assemblages indicate deposition in neritic to shallow marine environments.
