| Summary: | The Middle Jurassic Sargelu Formation spreads out widely in North-Eastern Iraq, particularly within the High Folds Unstable Shelf Zone. The Sargelu Formation was studied in two exposed sections, Hanjira and Gorin, in the Northeastern part of Iraq. The Lower contact of the formation with the Sehkaniyan Formation and the Upper contact with the Naokelekan Formation in the two sections appears conformable. The thickness of the Formation in the Hanjira section is 40m. and in the Gorin section is 70 m. The sampling was done by taking samples from two sections and thin sections were made for all samples and were studied under a polarizing microscope. Three main microfacies donated as M, W, P, and eight submicrofacies were diagnosed which reflects the deposition of the formation within the FZ-1 zone known as the Deep Sea Basin and the FZ-2 known as the Deep Shelf. |
