Abstract
AbstractTwenty-six rock samples were collected from Qarah Chaugh-Dagh section, 50 km northwest of Kirkuk city. Succession, ca. 61 m thick, belongs to the Azkand Formation. It is dominantly composed of fossiliferous foraminiferal limestones, which can be divided in two superposed units. Unit I is composed of fine- to coarse-grained bioclastic packstone-type deposits, while Unit II comprises fine- to very coarse-grained bioclastic packstone- to boundstone-type deposits. In this study, fifteen genera and with twenty-eight species of larger foraminifera were described and figured, associated with two species of corals and algae. Based on the distribution of the larger foraminifera, two assemblage biozones have been recognized in the Azkand formation. These assemblages of larger foraminifera indicate the age of the section is the Latest Oligocene (Assemblage zone I) (Chattian) to Early Miocene (Assemblage zone II) (Aquitanian).KeywordsLarger foraminiferaAzkand FormationLate OligoceneEarly MioceneKirkukNortheast Iraq
