Sandstone. Sandstone is composed of mineral grains (commonly quartz) cemented together by silica, iron oxide, or calcium carbonate. Sandstones are typically white, gray, brown, or red. Red and brown sandstones are colored by iron oxide impurities. Most sandstones feel gritty, and some are easily crushed (friable) and break up to form sand.
