Abstract

A Detailed calcareous nannofossils study for the Mushorah Formation from subsurface
section at Az. (29) well, Ain Zalah oil field, Northwestern Iraq. This is the first
documentation of calcareous nannofossils in the Mushorah Formation, the
Paleontological classification of this flora led to determine forty species. The
nannobiostratigraphic analysis suggested three calcareous nannofossils biozones these
are: (1) Calculites obscurus Interval Biozone; (2) Broinsonia parca Interval Biozone; (3)
Misceomarginatus pleniporus Interval Biozone. These biozones concluded that the age
of studied section of the Mushorah Formation is Early to Middle Campanian
