According to the tectonic
division of Iraq (Numan, 2001), the area under study covers
the Foothill and Mesopotamian zones of the quasiplatform
foreland of Iraq (Fig. 2). The main axis of the basin is NW-SE
in which the sandy and clayey facies of the Late Miocene
Injana Formation envelope the contemporaneous evaporatic
facies of the Middle Miocene Fat’ha Formation (Al-Mashadani,
1984)).
