Salam I. Al-Dulaimi ^[2] | Ahmed Fawzy Saeed

Abstract: Khasib Formation has been studied in four wells (Mj 1, Mj 3, Mj 4 and Mj 5. ) within Majnoon oilfield, Southern Iraq. One hundred and sixty thin sections have been studied by microscope in order to determine fauna and observed the microfacies. Twenty five species belonging to the foraminifera genera Contusotruncana fomica, Dicarenella asymetrica, Dicarenella concavata, Dicarenella primitive, Globotruncana arca, Globotruncana linnena, Globotruncana lapparenti, Globotruncana bulloides, Globotruncana elevate, Helvetoglotruncana helvetica, Hetrohelix glubosa, Hetrohelix moremani, Hetrohelix reussi, Hetrohelix planate, Leavihetrohelix pulchra, Marginotruncana coronata, Marginotruncana marginita, Marginotruncana renzi, Marginotruncana sigali, Muricohedbergilla delrioensis, muricahedbergila planispira, Marginotruncana schenegansi, Whitenella baltica, Whitenella brittonensis, Whitenella paradubia Six range biozones were distinguished. These biozones are Dicarinella primitiva range zone, Dicarinella concavata range zone, Helvetoglobotruncana Helvetica range zone, Dicarinella asymetrica range zone, Marginotruncana schneegansi range zone and the Globotruncanita elevata range zone.
