Physical properties
Hardness of 6-7 on Mohs scale, typically tan, brown, or reddish color, dull luster, composed mostly of quartz and feldspar grains.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, over millions of years in marine, desert, or river environments.
Uses & applications
Widely used in construction as a building and paving material, as well as in the manufacture of glass and abrasives.
Geological facts
Sandstone formations often display distinct visible layering or bedding planes that record ancient environmental conditions.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible mineral grains. Commonly found worldwide in sedimentary basins and arid regions.
