Abstract :

Tirgan Formation southeast of Ghochan (Dodanlu section) is composed of 615 meters of carbonateclastic rocks. Its lower contact is gradual with Shurijeh Formation and Its upper contact with Sarcheshmeh Formation is gradual too. In this research, Dodanlu section was measured and 100 thin section have been provided. Based on microfossils, Barremian-Aptian age has been determined for Tirgan formation. In this study 14 carbonate microfacies and 2 lithofacies have been recognized. Each of carbonate microfacies has been deposited in diffrents parts of Intertidal, Lagoon, Barrier and open marine sedimentary environments. Facies analysis of Tirgan Formation in the study area and comparison with modern system environments indicate that these facies have been deposited in a homoclinal ramp type of carbonate platform.
