Physical properties
Hardness of 6-7 on Mohs scale, reddish-brown color due to iron oxide cement, dull to vitreous luster, and granular texture with quartz grains.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, often in desert or arid terrestrial environments over millions of years.
Uses & applications
Widely used as a dimensional building stone, for paving, landscaping, and in historical architecture.
Geological facts
The red color comes from iron oxide (hematite) coating the sand grains. Many famous monuments and geological formations, like canyon walls, are carved from sandstone.
Field identification & locations
Easily identified by its visible sand grains, gritty texture, and layered bedding structures. Found worldwide in sedimentary basins and desert regions.
