TY - JOUR ID - TI - MICROFACIES AND BIOSTRATIGRAPHY OF BABA FORMATION (LATE OLIGOCENE) IN BAI HASSAN, OIL WELL-25, KIRKUK AREA, CENTRAL NORTH IRAQ AU - Imad M. Ghafor PY - 2011 VL - 7 IS - 3 SP - 25 EP - 32 JO - Iraqi Bulletin of Geology and Mining مجلة الجيولوجيا والتعدين العراقية SN - 18114539 AB - Larger Foraminifera in the Baba Formation (Middle Oligocene) are discussed. The investigation is based on a well sequence of limestone in Bai Hassan oil well -25, Kirkuk area central northern part of Iraq. Baba Formation is subdivided into three microfacies, which are: Fine to very coarse larger Foraminifera packstone, Fine bioclastic smaller Foraminiferal packstone and Fine bioclastic smaller Foraminiferal wackestone. The depositional environment of Oligocene Carbonate may be a part of an attached platform area, where more or less open marine prevailed through out.
