| Abstract | ||
| The present study deals with the biostratigraphy succession of Kolosh Formation in Hajran area North Iraq. Fifteen planktic foraminiferal species belonging to five genera have been identified within the studied section. Depending on the stratigraphic distribution of planktic foraminiferal species, the succession was devided into two biozone and three subzones, biostratigraphic zones are recognized in these foraminiferal bottom to top. 1-Parasubbotina pseudobulloids Interval Zone. 1-A- Subbotina trivialis partical Range Subzone. 1-B- Subbotina triloculinoides Interval Subzone. 1-C- Globanomalina compressa Interval Subzone 2- Praemurica uncinata Interval Zone These zones are correlated (locally and regional) with similar planktic foraminiferal. The age of this formation is Early Paleocene. | ||
