Abstract

Mishrif formation, south of Iraq was studied via checking 190 thin section collected from a well (Helfaia - 1). The limestone of the studied area consists of skeletal grains like planktonic foraminifera and echinoderms. The most prominent digenetic processes are delomitization and parite, this formation are divided into three water zones: high, mobilized and low.
