Physical properties
Hardness of 6-7 on Mohs scale, predominantly tan to brown color with visible quartz grains, dull to vitreous luster, and a granular texture.
Formation & geological history
Formed through 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, and for paving, as well as in the manufacture of glass and abrasives.
Geological facts
Sandstone formations often preserve ancient ripple marks and fossils, providing key insights into prehistoric environments.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible sand grains; commonly found in deserts, canyons, and sedimentary basins worldwide.
