Srood Farooq Naqshabandi


The Kolosh Formation is belongs to Paleocene –Early Eocene cycle, this cycle is characterize by a complete development in the basin of deposition in all parts of Iraq.

This study assessed to find the age of Kolosh Formation, dinoflagellate cysts as a main tool were used for this purpose through analyzing twelve (12) samples taken from Dokan area Sulaimani Governorate, the samples were treated by normal palynological analyses used in the world, the results showed presence of 15 genera and 19 species of dinoflagellate cysts in the formation, the determined plynomorphes were used to draw a rang chart, which used to subdivide the section to many biozones, named shortly as (P.Z1, P.Z2, and P.Z3), and to show the distribution of palynomorohes, in addition to the age of the formation.

The assigned biozones were correlated with other studies done before for the same age in Iraq at Shaqlawa area, and outside of Iraq with those of Germav Formation located in SE Anatolia, Turkey
