Physical properties
Hardness 6-7 on Mohs scale, tan to reddish-brown color, dull luster, clastic texture with visible sand grains, specific gravity 2.2-2.8.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, in marine, desert, or river environments over millions of years.
Uses & applications
Widely used in construction for building stone, paving, and retaining walls, as well as in manufacturing glass and abrasives.
Geological facts
Sandstone formations can store vast amounts of groundwater and petroleum, making them crucial reservoirs for hydrogeology and energy industries.
Field identification & locations
Easily identified by its gritty texture and visible sand grains; commonly found in sedimentary basins, cliffs, and desert regions worldwide.
