Abstract: 

Two sections are measured and Sampled in Brojen and Semirom areas.The Brojen section is located 35 Km southwest of Brojen and consists of marls and olive-green shales belonging to Gurpi Formation and sandy limestone, marls and rudists limestone that overlain by red to green marl and shale and massive limestone belonging to Tarbur Formation. The Semirom section is located 57 km southwest of Semirom. It consists of grey marls and shales belonging to Gurpi Formation and marly limestone and massive limestone belonging to Tarbur Formation. Micropaleontological and palynological investigations reveal that the recovered assemblage of Brojen section contain 8 species belonging 8 genera of planktonic and benthic foraminiferas, 6 species belong to 5 genera of dinoflagellate and 15 genera with 12 species of spores and pollen. A large number of foraminiferal linings, wood materials and organic matters are also recovered. The recovered assemblage from upper part sediments of the Gurpi Formation and lower part of Tarbur Formation in Semirom section consists of 9 species belong to 11 genera of foraminiferas. On the basis of recovered assemblage one biozone of planktonic foraminiferas, two biozones of benthic forminiferas and one biozone of dinofellagellate were identified.
