Physical properties
Hardness varies from 6 to 7 on the Mohs scale depending on cementation. Displays a reddish-brown color due to iron oxide, a dull earthy luster, and a gritty texture composed of visible quartz grains.
Formation & geological history
Formed through the accumulation, compaction, and lithification of mineral particles or rock fragments, typically in desert or river environments over millions of years.
Uses & applications
Commonly used in building construction, paving, decorative facing stone, and historical monuments.
Geological facts
The distinctive red color is caused by iron oxide coatings on the sand grains. Famous geological formations like Zion National Park are carved entirely from red sandstone.
Field identification & locations
Easily identified by its visible sand grains and reddish hue. Found worldwide in regions with ancient arid or fluvial sedimentary basins.
