Physical properties
Hardness of 6-7 on the Mohs scale, features distinct tan and gray banding, dull to vitreous luster, and a granular quartz crystal structure.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, often displaying Liesegang banding from groundwater iron diffusion.
Uses & applications
Used primarily as decorative landscape stones, ornamental items, and occasionally in masonry.
Geological facts
The striking concentric patterns are created by chemical precipitation rather than original deposition layers, making each specimen uniquely patterned.
Field identification & locations
Easily identified by its prominent color banding and granular texture; commonly found in riverbeds and sedimentary basins worldwide.
