In general, the main objectives of this study are: 1-Determining relative age of these deposits using foraminifera and calcareous alga (carbonate part) as well as their stratigraphic position (evaporite and silici-clastic parts) 2-Identifying and analyzing facies and also checking vertical and horizontal changes of facies 3-Interpreting depositional paleo environment and offering depositional model 4-Identifying depositional sequences and sequence boundaries by using fossils and other data and comparing sea level fluctuation at the time of deposition with global eustatic curve of Haq et al.
