Abstract
The Lower-Middle Miocene succession in kirkuk area include the Serikagni, Euphrates, Dhiben, Jeribe and Fatha formations in addition to Govanda and Ghar formation. The Euphrates, Dhiban, and Jeribe formations for study in Ja-26 and Hr-41 wells at Kirkuk area have similar facies and difficult recognized in order to Dhiban Formation separated with them. Therefore Euphrates ,Dhiban, and Jeribe formations are favored one group where to be similar in paleoenvironment depositonal and facies analyses. Which most them are formed from restricted marine and shallow open marine environments that consisting of lime mud stone, wakestone and packstone which consist skeletal grains of fossils especially milolid and nonskeletal grains of pellits and peloids in addition to dolomite and dolomitic mud and wackestone. The sabkha environment is recognized to Dhiban Formation and at the Jeribe Formation there are fixed occurrence of blue marl facies which represent the deep marine environment and fossilifrous peloidal packestone-grainestone facies represent shoal environments. The Fatha Formation and Serikagni Formation are considered resigning formations where Serikagni Formation is recognized by planiktonic deep marine environment while Fatha Formation is recognized dependence on location of sequence stratigraphy that is characterized high thick of salt, gypsum, anhydrate rocks in addition thin interbeded carbonates rocks.
