Bauxite, the ore of aluminum, is a lateritic deposit consisting mainly of aluminium hydroxide. When basaltic rock weathers, the equivalent of clay is greenish chlorite, also a flaky mineral. As our example of a clay, let's take the valuable kaolin, a pure form of clay that forms a slippery white mud, named after its original source in China.

Sand composed almost exclusively of olivine grains is rare. Olivine is a common rock-forming mineral of certain igneous rocks but it is very unstable under the atmospheric conditions and will therefore decay quickly. The most famous example of olivine sand is Papakolea Beach near the southern tip of Hawaii Island (Big Island) but it is not the only one: Is Papakolea the only green beach.
