Physical properties
Hardness of 6-7 on the Mohs scale, reddish-brown color due to iron oxide, dull to earthy luster, composed of cemented mineral particles.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, often in desert or river environments over millions of years.
Uses & applications
Widely used as a construction and building material, for paving, and in landscaping.
Geological facts
The red color is typically caused by hematite or goethite acting as a natural cement between quartz grains.
Field identification & locations
Identified by its visible sand grains and reddish hue, commonly found in desert regions, ancient riverbeds, and sedimentary basins worldwide.
