| Popis: | This study aims to diagnose microfacies of the Jeribe Formation to determine depositional environments and derivation depositional model for this formation. The study consisted of two wells in the Hamrin anticline north of the Saladin Governorate within the foothill zone. In the study area, the lower contact of the Jeribe Formation is unconformable with the Dhiban Formation, whereas the upper contact is conformable with the Fatha Formation. Depending on the microfacies analysis, four significant microfacies were distinguished, including mudstone, wackestone, packstone, and grainstone, and then divided into eight submicrofacies types depending on grain types. The microfacies analysis of the Jeribe Formation revealed the recognition of five environments: open-marine (middle ramp to inner ramp), restricted, shoal, lagoon, and partial environments. The majority of microfacies are determined within the inner ramp setting. The Jeribe Formation was deposited in a shallow marine environment. |
