Physical properties
Mohs hardness: 6-7; Color: banded orange, red, and tan; Luster: dull to earthy; Texture: Granular/clastic; Specific gravity: 2.2-2.8
Formation & geological history
Formed by the accumulation and cementation of sand-sized mineral grains or rock fragments, typically through wind or water deposition. The colors are caused by iron oxide (hematite) staining.
Uses & applications
Used extensively in construction, architectural veneers, landscaping, and as a material for decorative tiles.
Geological facts
This specimen displays distinct rhythmic bedding or banding, often referred to as 'picture sandstone' or 'wonderstone' when the patterns resemble landscapes.
Field identification & locations
Identified by its gritty feel and visible horizontal layering. Commonly found in arid regions like the American Southwest (Utah and Arizona).
