Uma seção da Formação Pabdeh do Paleoceno-Oligoceno foi amostrada na Bacia Zagros, no sudoeste do Irã, para investigações palinológicas e avaliação de maturidade térmica e potencial de geração de hidrocarbonetos. Ao todo, 125 amostras de rochas foram coletadas e processadas palinologicamente. As amostras produziram assembleias ricas de cistos de dinoflagelados, nas quais foram identificadas 65 espécies de cistos. Algumas espécies-guia permitiram datação por meio do estabelecimento de sete biozonas de dinoflagelados de acordo com o arcabouço de biozoneamento europeu existente. As zonas de cistos de dinoflagelados permitiram atribuir a idade precisa da formação em estudo, a qual se estende do Neopaleoceno até o Eo-oligoceno. Para maturidade térmica, a coloração de esporos e grãos de pólen foi correlacionada com a escala padrão de cores da companhia de petróleo Shell. Propriedades das amostras, indicadas pela mudança de cor dos palinomorfos, sugerem que a formação é potencialmente geradora, podendo ter produzido petróleo.

Abstract Asmari Formation is the thick sequence of carbonate sediment in the range of Oligocene-Miocene which is deposited in the foreland basins of the Zagros and is considered as the original and most famous reservoir rock of Zagros basin. To study of lithostratigraphic units and sequence stratigraphy of this Formation, the section in the southeast of Norabad was selected. Field study indicated that Asmari Formation possessed the thickness of 401.5m and included 9 lithostratigraphic units. According to the study of microfacies, Stacking pattern and identification of main sequence level, three depositional sequences including two-second order and one-third order sequence were recognized. The sea-level curve in the studied section indicated that it was correspondence to the global sea level curve. These facies deposited in five environmental sedimentations as follow Open Sea Shelf (Fore Barrier), Bar, Lagoon, Back bar shelf, and Shoal. The environment is part of a carbonate platform that has been formed on an open shelf. In addition, according to the Study of foraminifer dispersion pattern the range of Asmari Formation in Norabad was suggested to be Oligocene (Rupelian- Chattian) to lower Miocene (Aquitanian- Burdigalian).
