| Abstract | ||
| Fat'ha Formation characterz ed by its wide distribution in Iraq, which is mainly consist of gypsum. Limestone and green marl, Sheik Ibrahim and Atshan ( Hammam Al-Elil) anticlines W & SW of Mousal city, wre selected for study in which this formation is well exposed and with considerable thickness. One hundred rock samples were collected the above two areas. The microscopic exmanination of 90 thin sections from limestone layers revealed the presences of the following genus: ( Ammonia, Elphidium, Quinqueloculina, Triloculina, Pyrgo, Spiroloculina, Austrotrillina, Borlis, Peneroplis, Praerhaphdionina, Discorbis, Nonion, Textularia). These assemblages are more likely indicationg the lagoonal and shallow water depositional environments. The pterological studies suggest that although Fat'ha Formation in both areas deposited in shallow , semi-restrict basin and most probably developed under an arid climate, but Atshan area ( Hammam Al-Elil basin) received terrigenous clastics than Sheik Ibrahim | ||
