Biostratigraphy of albian-santonian succession along Surdash to Shaqlawa areas, ne Iraq

الملخص EN

Three formations were studied along Surdash, Qallat, Khalakan, Hezob, Sektan, Degala and Shaqlawa areas in the Sulaimaniyah and Erbil governorates, NE Iraq.

These are: Dokan, Gulneri and Kometan formations.

The age of these formations are determined depending on the biozones of planktonic foraminifera, and the contact between each two formations was discriminated in the field and by microfossils content.

Eleven biozones were distinguished from Albian – Santonian age and at least two biozones up to seven biozones can be discriminated in each section along the study area.

Forty-nine species belong to twenty-four genera were used as species of biozones and coeval fossils support each zone.
