Physical properties
Hardness 6-7 on Mohs scale, reddish-brown color due to iron oxide cement, dull luster, clastic texture with visible sand grains.
Formation & geological history
Formed through the accumulation, compaction, and cementation 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 stone, and masonry.
Geological facts
The red color comes from hematite coating the individual quartz grains. Many ancient monuments and buildings are constructed from red sandstone.
Field identification & locations
Identified by its visible sand grains, gritty texture, and sedimentary layering. Found worldwide in ancient desert and fluvial deposits.
