    Sandstone is a sedimentary rock composed mostly of sand-sized grains cemented by clay, silica, carbonate, or iron oxide. In most places, the majority of the constituent grains are quartz. Sandstone often contains other mineral grains such as feldspar or mica, and very small fragments of pre-existing rocks. When cemented by silica, sandstone has great strength, making it suitable for structural uses.

    Like sand, sandstone may be any color, but the most common colors are tan, brown, yellow, red, gray and white. Although it is unusual some sandstone may be green in color.
