Physical properties
Hardness of 6 to 7 on the Mohs scale, predominantly tan to brown color, dull or earthy luster, clastic texture, and specific gravity around 2.2 to 2.8.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, primarily quartz, over millions of years.
Uses & applications
Widely used in construction as a building material, dimension stone, paving, and for manufacturing glass.
Geological facts
Sandstone formations often display distinct layering called bedding and can act as major reservoirs for groundwater and petroleum.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible mineral grains, commonly found in deserts, riverbeds, and ancient marine environments.
