Physical properties
Hardness of 6-7 on Mohs scale depending on cementation, typically tan, brown, or reddish, dull luster, and granular texture with visible quartz grains.
Formation & geological history
Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, chiefly quartz and feldspar, in marine, desert, or river environments.
Uses & applications
Widely used in construction as building stone, paving material, and in the manufacture of glass and abrasives.
Geological facts
Sandstone formations often preserve ancient desert dunes or riverbeds and act as major underground reservoirs for water and petroleum.
Field identification & locations
Identify by its distinct gritty, sandpaper-like texture and visible sand grains. Found worldwide in deserts, canyons, and sedimentary basins.
