Abstract :

Carbonate sediments of Permian age crops out in different parts of Iran, based on the foraminiferal content, they are attributed to Bolorian (?), Kubergandian to Dorashamian stages. These biogenetic limestones have plenty of Fusulinaceaa, non-fusulinid smaller foraminifers and algae, and they are a basis for determination of age, establishment of biozonation and paleogeography of Permian based on fusulind content. In some localities, chiefly in the north and northwest of Iran because of the distribution of Fusulinid are very rare paleoecological and paleo environmental factors. Despite these situation, smaller foraminifers, especially uniserial ones have a very important role in carbonate sediment make up, determination of age and reconstruction of paleoenvironment.In this paper, this important and crucial role of uniserial foraminifers is discussed.
