Mineralogical,geochemical,and textural analyses of the white sandstones(Abu Thora Fm.) of Carboniferous in the Abu Rodeiyim region show that they are fluviomarine,well-sorted,high-purity,and high-grade silica SiO2(average 99.56%).The results indicate that by simple treatment,the white sandstones can reach a high degree of purity,suitable for different industrial purposes(e.g.manufacture of silicon photovoltaic,crystal,and TV screens,art,and domestic and optical glass).
