| Abstract | ||
| This study is dealt with application of sequence stratigraphic concepts on the upper Cretaceous succession , precisely (Late Touronian – Early Campanian) sub cycle that includes (Khasib, Tanuma & Saadi ) formations at West Qurna oil field , southern Iraq.The study dependeds on microfacies analysis that shows there are four main microfacies and fifteen submicrofacies. That are distributed vertically and laterally along the extension of the West Qurna oil field. Depending on the microfacies analysis , the depositional environments has been determined as follows : sub-basinal ,slope , lagoon, shoal, open sea shelf, and the basinal environment. The sequence stratigrphic concepts have been used depending on well logs in addition to the petrographic description of microfacies , this concepts is Base level transiet cycles. The Sequence boundaries of the depositional systems have been detected . The transgressive systems tract reflects the deposition of Khasib Formation and the upper part of Sa’di Formation , in addition, the highstand systems tract reflects the deposition of Tanuma Formation and the lower | ||
