Abstract

Palynological investigation about 120 samples from 460m thick outcrop section of late Paleocene to early Oligocene of the Pabdeh Formation, southwestern in Iran yield 55 species of dinoflagellate results to defined 7 biozone. The quantities of marine palynomorph elements are indicated of open marine at this time, but a low increase number of spore and pollen in some of the sample indicated the condition for growth forest are suitable that consequent increase the harm climate and humidity. The species are common with different latitude and most of them cosmopolitan. Thermal maturity index measurement indicates oil prone in most of the samples.

Keywords: Pabdeh Formation; Dinoflagellatecyst; Paleogene; Palynostratigraphy; Thermalmaturity.
