Physical properties
Hardness of 6-7 on Mohs scale depending on cement, colors range from tan to reddish brown, dull to earthy luster, quartz-rich composition with granular texture.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, in desert, river, or marine environments over millions of years.
Uses & applications
Widely used in construction as building stone, paving material, and in the manufacture of glass and abrasives.
Geological facts
Sandstone frequently preserves ripple marks and ancient cross-bedding, providing geologists with vital clues about past wind and water currents.
Field identification & locations
Identify by its visible sand-sized grains and gritty texture; commonly found worldwide in desert regions, canyons, and ancient riverbeds.
