Composition of Sand. Sand comes from preexisting rocks. Therefore, sand will contain minerals that were already present before weathering commenced. An important thing to note here is that the minerals resistant to weathering will dominate sand'' composition.

· Sand Composition and Shape . Most sand is made of quartz or its microcrystalline cousin chalcedony, because that common mineral is resistant to weathering. The farther from its source rock a sand is, the closer it is to pure quartz. But many "dirty" sands contain feldspar grains, tiny bits of rock (lithics), or dark minerals like ilmenite and

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 mm to 2 which are larger than mm but smaller than mm are termed silt.. Sand is made by erosion or broken pebbles and weathering of rocks, which is carried by seas or rivers.

Sand is a very common unconsolidated sedimentary rock, with its particle size varying between and mm. It also has an extremely variable mineral composition. Many types contain quartz or silicon dioxide (SiO 2). Sand is primarily used in the glass and construction industry because of its chemical and physical characteristics.

Sometimes sand contains new minerals or mineral aggregates that were nonexistent in the source rocks. Notable example is a clay mineral glauconite which forms in marine sand and gives distinctive dark green color to many sand samples. In some instances glauconite in sand may come from disintegrated glauconitic sandstone nearby, but eventually it is of marine origin anyway.

Lunar soil is the fine fraction of the regolith found on the surface of the properties can differ significantly from those of terrestrial physical properties of lunar soil are primarily the result of mechanical disintegration of basaltic and anorthositic rock, caused by continual meteoric impacts and bombardment by solar and interstellar charged atomic particles over years.
