The current study including microfacies analysis and depositional environment aspects of (10) rock samples from Euphrates Formation in outcrop location is at Al-Baghdadi city, with a thickness of this formation 19 meters, It is consists of gray, hard, porous, weathered, Peloidal, and dolomitic limestone. The layer of basal Conglomerate with a thickness of about 6 meters in the study outcrop, which consists of calcareous Conglomerate of different sizes, indicates a stratigraphic unconformity, which is the contact between the Miocene and Oligocene formations. The age of this formation is lower Miocene. The formation within this section is rich in benthic foraminifera and other types of fossils such as corals, echinoderms, and pelecypoda. In this study, determine three main types of microfacies were distinguished in this Formation, namely: peloidal lime grainstone, lime wackstone, dolostone. By studying the microfacies types and abundance of benthic foraminifera and other species, the depositional environment of Euphrates Formation was deduced, which represents a restricted marine.
