Abstract
Tirgan and Sarchshmeh Formations, Aptian age, belong lithostratigraphically to Kopeh Dagh, for many reasons, with reference to lithology and biology contents that can be compared with Orbitolina limestone in the Central Iran. The similarities between these unites were the reason to compare the Mozdooran section (Kopeh Dagh) with Baharestan section (Esfehan)  by studying 71 lithology samples and 57 washing samples and found  many similarities in lithology and biology.           
The similarities of environments and type of sedimentation basins, would command this possibility that Aptian to Albian sea of the Kopeh Dagh was spread out through the Central Iran. This result can indicate the close relation between the Kopeh Dagh and Central Iran in the aforementioned time periods.
