Examples of non-metallic rocks and minerals of economic interest include coal, gemstones, construction aggregate (gravel or riprap), building stone, salt, gypsum and anhydrite, industrial-grade clays, fluorspar, phosphate, nitrate, and barite. Peat moss is included here because it is a fossil resource (i.e., it is mined faster than it is formed) similar in many respects to coal.
