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.
