Calcareous Nannofossils Biostratigraphy of Shiranish Formation (K-306) well, Northern Iraq
Twenty Samples of Shiranish Formation from the well (K-306), Kirkuk area, northern Iraq, are collected and studied on the basis of stratigraphic ranges of the recorded calcareous nannofossils. Eighty-nine species in the studied section reveals five biozones arranged from oldest to youngest as follows: 1.Quadrum trifidum Interval Biozone (CC22) Part 2.Tranolithus phacelosus Interval Biozone (CC23) 3.Rienhardtites lives Interval Biozone (CC24) 4. Arkhangelskilla cymbiformis Interval Biozone (CC25) 5. Nephrolithus frequens Rang Biozone (CC26) Part These Biozones are correlated with other calcareous nannofossils biozones, from both local and regional sections, leading to conclude the age of CampanianMaastrichtian.
