The sedimentology of the Rus and Jil Formations.

This work deals with, the study of sedimentology of the lower Eocene Rus and Jil Formations at Najif and Al-Muthanna Governorates, Southern Iraq. The study includes petrography, diagenesis, facies analysis and depositional environment of the formations. Two major lithofacies are recognized in the studied sections, namely carbonate lithofacies and evaporite lithofacies. The carbonate lithofacies is divided into five microfacies whereas the evaporite lithofacies is divided into three sublithofacies.
