Chemical sedimentary rocks are formed by direct chemical precipitation from water. While some limestones and cherts may form in this manner, evaporite deposits consisting of halite, gypsum, and other salts are the most common. Because sediment gets buried, and if exposed gets eroded, older sedimentary rocks show less exposed outcrop area than younger sedimentary rocks. Over 40% of .
