| Abstract | ||
| Biostratigraphy of the Shiranish Formation is investigated in Zozik anticline located whithin high folded zone .Depending on lithology of the Shiranish Formation in the studied section is devided to three rock uints, lower unit consisting of marly limestone, middle units consisting of Limestone ,marly limestone, and shale and the upper units consisting of Limestone and marly limestone. Shiranish formation in the Diana area is bounded from below by the Bakhma Formation with a unconformity relationship, and from above by the clastic Tanjero Formation with a conformity and gradual relationship. The purpose of this paper is to record the planktic foraminiferal and determinmind the biostratigraphy zones, and correlation them locally and regional to determine the age of formatio. In this paper has been determined 50 species of planktic foraminifera are described in 48 samples. The formation divided ito four biozones (Radotrucana calcarata Interval biozone,Globotruncanella havanensis Interval Biozone, Globotruncana aegyptiaca Interval Biozone, Gansserina gansseri Total Biozone) Based on this, the age of formation was determined by the Late Campanian to Early Maastrichtian. | ||
