Physical properties
Hardness of 6-7 on the Mohs scale, tan to reddish-brown color, dull or earthy luster, granular texture, and specific gravity of 2.2-2.8.
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 material, dimension stone, paving, and in the manufacturing of glass.
Geological facts
Sandstone is porous and permeable, making it an excellent natural aquifer for storing groundwater and petroleum.
Field identification & locations
Easily identified by its visible sand grains and layered deposition; common worldwide in deserts, canyons, and ancient riverbeds.
