The source materials of heavy mineral sand are metamorphic and igneous rocks. Metamorphic rocks give rise to sand containing kyanite and garnet for example although the latter may crystallise from magma as well. Magnetite is mostly of igneous origin. Heavy mineral sand is a natural mineral concentrate which is often mined commercially.
