Physical properties
Hardness of 6-7 on the Mohs scale, earthy to vitreous luster, fine to medium-grained texture, and distinct iron-oxide banding.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, often in desert or beach environments over millions of years.
Uses & applications
Used locally in landscaping, decorative gravel, and occasionally as a building material.
Geological facts
The distinct bands are typically created by circulating groundwater depositing iron oxide and other minerals through porous layers.
Field identification & locations
Identified by visible sand grains and characteristic parallel stripes; commonly found in riverbeds and coastal regions worldwide.
