Physical properties
Hardness of 6 to 7 on the Mohs scale, reddish-brown color due to iron oxide cement, dull luster, clastic texture with fine to medium 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
Widely used as a dimensional building stone, paving material, and in landscaping applications.
Geological facts
The distinct red color is caused by hematite coating the quartz grains, frequently forming in arid ancient desert climates.
Field identification & locations
Easily identified by its gritty texture and visible sand grains, commonly found in riverbeds, desert regions, and layered sedimentary cliffs.
