Physical properties
Hardness of 6-7 on Mohs scale, reddish-brown color due to iron oxide, dull to vitreous luster, clastic texture, specific gravity of 2.2-2.8.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, typically in desert or river environments.
Uses & applications
Widely used in construction, building facades, paving stones, and landscaping monuments.
Geological facts
The red color is caused by iron oxide (hematite) coating the quartz grains. Many famous historical monuments and ancient temples are carved from red sandstone.
Field identification & locations
Identify by visible sand grains and a gritty texture, commonly found in sedimentary basins and arid regions worldwide.
