Mineral sand deposits are formed from the erosion and weathering of pre-existing igneous rocks such as granite, pegmatite and basalt. Over 60 to 200 million years the combinations of wind and water from ancient rivers and seas have leached the minerals from their past rocks and concentrated them into beach and dune deposits.

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.

Sand is a mixture of small grains of rock and granular materials which is mainly defined by size, being finer than gravel and coarser than silt. And ranging in size from 0.06 mm to 2 mm.Particles which are larger than 0.0078125 mm but smaller than 0.0625 mm are termed silt.. Sand is made by erosion or broken pebbles and weathering of rocks, which is carried by seas or rivers.
