| Abstract | ||
| The present study deals with the biostratigraphy and depositional environment of (Late Turonian – Early Campanian) represent dy Khasib, Tanuma and Saadi Formations in well Agel -12- Northeastern Tikrite. Determination of three microfacies in Khasib, one microfacies in Tanuma and three microfacies in Saadi Formations. Depending on microfacies the paleoecologe of Khasib Middle shelf – Upper Bathyal environment, Tanuma Shelf Margin environment and Saadi Formations sediment in Middle shelf – Upper Bathyal. Twenty planktic foraminiferal species belonging to eight genera have been identified within the studied well. Depending on the stratigraphic distribution of planktic foraminiferal species, the succession was divided into five biozones. These zones are correlated (locally and regional) with similar planktic foraminiferal 1- Marginotruncana sigali interval Zone. 2- Dicarinella primitive interval Zone. 3- Dicarinella concavata interval Zone.h 4- Dicarinella asymetrica Total Range Zone. 5- Globotruncanita elevata Partial Range Zone. Age of Khasib Late Turonian, Tanuma Coniacian and Saadi Santonian - Early Campanian. | ||
