【 摘 要 】

Palynological investigation on 132 samples from the 428m thick outcrop sectionof Late Paleocene to Early Oligocene of the Pabdeh Formation in southwestern Iran yielded 55species of dinoflagellate cysts and allowed establishment of seven biozones. Quantity of marinepalynomorph elements indicate an open marine environment at that time interval but, a slightincrease in number of spore and pollen grains in some samples indicate suitable conditions forforest development as a consequence of increase in climate humidity. The species are commonin various latitudes and most of them are cosmopolitan. Thermal maturity index measurementindicates oil prone nature for majority of the samples.
