Physical properties
Hardness of 6-7 on the Mohs scale, earthy luster, and distinct reddish-brown and tan bands. Composed primarily of cemented quartz grains with iron oxide staining.
Formation & geological history
Formed through the accumulation, compaction, and lithification of quartz sand grains in desert or beach environments over millions of years.
Uses & applications
Commonly used in construction, landscaping, decorative stone, and as a raw material for glassmaking.
Geological facts
The distinct banding is caused by varying iron oxide concentrations percolating through permeable layers of sand during diagenesis.
Field identification & locations
Easily identified by its gritty texture and visible sand grains arranged in alternating color layers. Found globally in ancient sedimentary basins.
