Beach and desert sand is primarily composed of quartz crystals due to quartz's high resistance to mechanical and chemical weathering. Quartz can be found in sand deposits, high purity crystal deposits and is found to some degree as a minor component in most mineral formations. Quartz is highly abrasive with a Mohs hardness value of 7.0.
angular grains become rounded, feldspars are weathered to clay minerals, particle size becomes smaller due to abrasion, quartz fraction increases as other minerals are winnowed out. Well-rounded sediment suggests sediment has been _________.
