Stratigraphy and Nannofossil Biozonation of Sarmord Formation on the Qaywan Anticline in Sulaymaniyah Governorate, Northern Iraq

The Sarmord Formation is one of the overlooked formations that require more investigations than that achieved before. There are many problems in its definition, age, stratigraphy and aerial distribution. Previously in most parts of the Sulaymaniyah, it is not mapped and its outcrops combine...
