The search implemented to measure the rate and percentage of Fe radicals and Ions, beside minerals by choose two site on both Iraqi rivers in Baghdad. The Tigris river, manifestation of dark oxides reflected Fe consist of it (41.and 39.9%), Chlorites (5.3 and 8.1%) and Pyroxene (5.8 and 4.7%) and others, while the Euphrates river sediments, opaque minerals were detected represented by Fe oxides (43.6 and 43%), Chlorites (6.6 and 8.8%), Pyroxene (6 and 4.5%), In the other hand, light sand minerals in the sediments of the Tigris river, as mono crystalline Quartz (28.4, 29.9%), Polycrystalline (2.4, 1.1%), Microcline (1.2, 1.6%), Orthoclase (3.1, 4.7%) and Plagioclase (1.2 ,1.5%) and Carbonate rock crumbs (36.5 and 35.4%) and Churt rock (7.3 and 6.5%), and igneous rocks (2.1 and 1.6%), metamorphic fragments (1.9 and 2.3%), clay fragments (5.2 and 7.8%), and Evaporates (6.2 and 4.5%). While the Euphrates river, light minerals observed mono crystalline (24.5 and 26.6%) and Polycrystalline Quartz (2.6 and 1.7%) Microcline (2.8 and 1.2%), Orthoclase (2.4 and 4.4%), Plagioclase (3.6 and 2.4%), Carbonate rock crumbs (32 and 37.5%), Churt rock (9 and 5.9%) and igneous rock fragments (2.5 and 1.6%). Metamorphic rocks (3.2 and 2.8%), clay rocks (8.3 and 6.2%), and Evaporites (4.5 and 5.1%).The predominance of rock fragments minerals, Quartz (as for Feldspar), the predominance of Orthoclase was appeared, beside dominance of Magnetite minerals over Hematite in the fine and coarse sand separated, and the superiority of coarse sand in the proportion of oxides The results showed the predominance of rock fragments, then Quartz, while Feldspar showed the predominance of the Plagioclase mineral and the predominance of Magnetite mineral only without Hematite in the fine and coarse sand separated, and the superiority of coarse sand in the proportion of oxides. ides.
