Banded sandstone

Quartz-rich sandstone (quartz arenite or feldspathic sandstone; exact type cannot be determined from the image)

AI-generated identification · may be incorrect

Fine-grained, tan to reddish-brown with parallel pale bands and a matte surface. Sandstone is typically Mohs 6–7 where quartz-rich; individual grains are too small to assess here.

Physical properties

Fine-grained, tan to reddish-brown with parallel pale bands and a matte surface. Sandstone is typically Mohs 6–7 where quartz-rich; individual grains are too small to assess here.

Formation & geological history

Formed as sand accumulated in layers and was compacted and cemented, with iron oxides likely contributing the reddish color. Its age and depositional environment cannot be determined from the image.

Uses & applications

Commonly used for building stone, paving, and landscaping; this small piece is mainly decorative or a collection specimen.

Geological facts

The visible stripes are sedimentary layering, likely reflecting changes in grain size or mineral content.

Field identification & locations

Look for sand-sized grains and layered texture; common in sedimentary basins worldwide. This appears to be a small, possibly smoothed fragment.
