Refference : Geosciences Scientific Quarterly Journal,No.:17-18,P.:24 Publishing Year : 1374 Abstract : A total of 12 samples from the Bayandor Formation (Proterozoic sediments) in Kuh-e-Bayandor Type Section Area at southern Zanjan town, northwest Iran were selected and treated for palynological study. This study was undertaken in order to determine the age relationships of the Bayandor Formation. A Total of 13 acritarch taxa were encountered in the studied samples of this rock unit, including Leiosphaerida crassa, Leiosphaeeridia temata, Leiosphaeridia JacutIca Synsphaendium sp Lophosphaeridium granulatum Satka squamitera Pteivspermopsimorpha insolita, Arctacellulera, ellipsoidea Arctacellularia tetragonala Coneosphaera. sp, and Oscillatoropsis sp. So far, the above- mentioned acritarch and cryptarch taxa have been recorded from Late Riphean sediments of China, Russia, Canada and Africa. Therefore, based on palynotogical data, Late Riphean age is suggested, for the Bayandor Formation in the Type Section Area. Leiosphaeriadia crassa Leiosphaendia tameta, Leiosphaeriadia jacutica Lophosphaeridium granulatum, Synsphaerithum sp Ptecospermapsimorpha insolita Satka squemifara, Arctacellularia tetragonala, Arctacellularia ellipsoidea, Oscillatoriopsis sp., Coneosphaera sp.
