With the aim of studying heavy, light and light minerals of sand separated for some soils of Al-Diwaniyah province Where three locations were selected, the first location was in Al-Nouriah area, the second location was in Al-Shanafiya area, and the third location was in Al-Bdeir area. The light sand minerals were separated from the heavy metals and their percentage was determined by point counting. The results showed the following: The results showed the presence of heavy sand minerals in all the study soils represented, in the limestone soils, the percentage of opaque minerals was (37.8), chlorite (9.6%), orthopyroxene (2.0%), clenopyroxene (4.7%), hornblende (7.3%), clacovan (0.3%) and biotite ( (4.9%), muscovite (4.4%), zircon ((5.7%), tourmaline (4.4%) and rutile (2.6%), karanite (5.1%) and epidot (6.5%), while the gypsum soil was the percentage of opaque minerals (36.6%), chlorite (3.9%), orthopyroxene (2.1%), clenopyroxene (1.8%), hornblende (3.5%), and glacophan (0.9%). ), biotite (2.4%), muscovite (6.6%), zircon (5.2%), and tourmaline (4.4%).The percentage of opaque minerals was rutile (3.3%), karanite (4.4%), epidot (6.4%), sand dunes were opaque minerals (32.6%), chlorite (7.9%), orthopyroxene (3.0%), clenopyroxene (2.7%), hornblende (4.5%), and glacovan (1.2%) and biotite (5.7%), muscovite (4.3%), zircon (9.2%), tourmaline (7.4%), rutile (4.3%), carnitate (4.4%), and epidote (6.4%).The results showed the light sand minerals for the study soils, and their percentages in the limestone soils were for monocrystalline quartz (42.2%), polycrystalline quartz (2.7%), microcline (2.5%), orthoclase (2.3%), plagioclase (2.5%), carbonate rock pieces (33.7%), and flint stone. (5.5%) and igneous rocks (2.2%) Clay rocks (6.7%), gypsum (5.2%), metamorphic rocks (1.8%), clay-coated particles (1.6%), and other minerals (0.9%). As for gypsum soil, the percentage of mono-crystalline (29.6%) and polycrystalline quartz (2.2%) micro-cleans (3.3%), orthoclase (4.5%), plagioclase (3.4%), and carbonaceous rocks (29.3%). Flints (5.2%), igneous rocks (2.3%), clay rocks (3.1%), gypsum (11.6%), metamorphic rocks (3.5%), clay-coated granules (2.1%) and other minerals (0.9%). Monocrystalline quartz (46.6%) and polycrystalline quartz ((2.2% .) Microcline (3.3%), orthoclase (4.5%), plagioclase (3.4%), Carbonite (19.3%) and Flint (5.2%)igneous rocks(2.3%), clay rocks (3.1%), gypsum (3.6%), metamorphic rocks (3.5%), clay-coated particles (2.1%) and other minerals (0.9%).
