Sandstone materia is the kind of stone. Sandstone material(sometimes known as arenite) is a sedimentary rock composed mainly of sand-sized minerals or rock grains. Most sandstone material is composed of quartz and/or feldspar because these are the most common minerals in the Earth's crust. Like sand, sandstone material may be any color, but the most common colors are tan, brown, yellow, red, gray and white. Since sandstone material beds often form highly visible cliffs and other topographic features, certain colors of sandstone material have been strongly identified with certain regions.
