AbstractA surface section of Jaddala Formation was studied near Bara Village in the western plunge area of Sinjar anticline northwestern Iraq . The sequences under study consist of marl, marly limestone and limestone beds. Detailed study of planktonic foraminifera revealed (38) species belonging to (14) genera, the stratigraphic distribution of these species permits the regognition of five zones, these are: Morozovella aragonensis Zone, Acarinina pentacamerata Zone, Acarinina bullbrooki Zone, Globigerinatheka subconglobata Zone and Acarinina collactea Zone. These zones indicate that Jaddala Formation is of Early - Middle Eocene age.
