Physical properties

Hardness of 6 to 7 on the Mohs scale, typically reddish-brown to pink due to iron oxide, dull luster, and granular texture composed mostly of quartz grains.

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

Commonly used in building construction, paving, monuments, and landscaping.

Geological facts

The reddish hue is caused by hematite or goethite acting as a natural cement binding the sand grains together.

Field identification & locations

Easily identified by its visible sand grains and layered appearance, found abundantly worldwide in ancient sedimentary basins and arid regions.
