Most sands are usually made out of quartz grains (pure silica), but can contain things like fragments of shells, corals etc. Desert sands normally appear red in colour, due to oxidation and consequent red staining of the sand grains. Some sands are made out of limestones, usually in tropical areas, and some contain minerals such as feldspar, magnetite, gypsum etc.
