A sedimentary rock formed from cemented, sand sized mineral grains, most often quartz, laid down by wind or water and compacted into layers that record the direction the sediment once moved.

Facts
Partially Attested
Chemical FormulaNo single fixed formula; sandstone is made mostly of sand sized grains cemented together. Quartz (SiO2) framework grains dominate most clastic sedimentary rocks including sandstone because quartz has exceptional hardness and chemical stability, though the cementing material varies (silica, calcite, iron oxide or clay). 1 Source states quartz (SiO2) dominates framework grains in clastic sedimentary rocks generally, not a specific percent composition for sandstone alone; the cement varies between specimens.

Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains, cemented together by another mineral.
Framework grains section
Quartz framework grains are the dominant minerals in most clastic sedimentary rocks; this is because they have exceptional physical properties, such as hardness and chemical stability.

Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts, and hence quartzite is a metasandstone.
