Nannobiostratigraphy of Jaddala Formation in Well(KH 12/7) West Iraq
Section: Article
Abstract
ABSTRACT Thirteen species of Calcareous Nanofossils were identified from the Jaddala Formation from well (KH 12/7) of depth (107-130 m.) west Iraq. The recorded calcareous nannofossils assemblages permits the recognition of two biozones these are (from top to bottom):2- Discoaster saipanensis Interval zone(Part) (CP14b) 1- Discoaster bifax Interval zone(Part) (CP 14 a)On the basis of biocorrelation with previous works Middle Eocene (Bartonian) age confirmed for the Jaddala Formation at the studied section.
