It consists mainly of marl, limestone and shale. The lower parts especially contain many interbedded limestone and shale that formed mane parasequences. It is conformably overlain by the Sanganeh and conformably underlain by the Tirgan Formations. These carbonate sediments have been deposited in shallow marine carbonate ramp. this sections have been studied by petrographic as well as cathodoluminescence microscopes to interpret the digenetic history of the carbonate rocks whit in the Sarcheshmeh Formation. After deposition, the Sarcheshmeh limestones have been affected by different diagenetic processes. These include cementation, micritization, borrowing, neomorphism, compaction, dolomitization, silicification, heniatitization. dissolution and formation of fractures and veins. These processes operated whit in four diagenetic environments including marine, meteoric, mixed marine-meteoric and burial. Paragenetic sequence! have also been interpreted for these carbonate rocks. We hope that this data can be used for the interpretation of post depositional history of the Aplian limestones in basin within the Kopet-Dagi basin and can also be used for further exploration for hydrocarbon reservoir in this basin.
