Physical properties
Hardness of 6-7 on Mohs scale, typically brown, tan, or reddish in color with a dull to earthy luster. Composed primarily of cemented quartz grains with a granular crystal structure.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, typically in desert, river, or beach environments over millions of years.
Uses & applications
Widely used in construction as a building material, paving stone, and in the manufacture of glass and abrasives.
Geological facts
Sandstone formations often display distinct layer bedding planes and can act as prolific aquifers or petroleum reservoirs due to their porosity.
Field identification & locations
Identify by its gritty texture like sandpaper and visible sand grains. Commonly found worldwide in ancient and active sedimentary basins.
