Physical properties
Hardness of 6-7 on Mohs scale. Colors range from tan, brown, yellow, to red due to iron oxides. Dull to earthy luster, granular crystal structure with quartz grains.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, over millions of years in desert, river, or marine environments.
Uses & applications
Widely used in construction as a building material, paving stone, and in the manufacture of glass and concrete.
Geological facts
Famous monuments worldwide, including Petra in Jordan and many ancient temples, are carved directly out of massive sandstone formations.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible sand grains. Found globally in sedimentary basins and arid regions.
