Likely sandstone fragment

Quartz-rich sandstone; exact composition cannot be determined from the photograph

AI-generated identification · may be incorrect

Tan to pale brown, matte and granular, with no visible crystals or cleavage. Sandstone hardness varies with cement, typically around 6–7 where quartz-rich; specific gravity is commonly 2.0–2.7.

Physical properties

Tan to pale brown, matte and granular, with no visible crystals or cleavage. Sandstone hardness varies with cement, typically around 6–7 where quartz-rich; specific gravity is commonly 2.0–2.7.

Formation & geological history

Formed when sand grains accumulated and were compacted and cemented, often in river, beach, or desert environments. Its age cannot be established from appearance alone.

Uses & applications

Common sandstone is used as building and paving stone, landscaping material, and aggregate; this small fragment appears to have little commercial value.

Geological facts

Sandstone can range from friable to very durable depending on its cement, which may be silica, calcite, or iron oxides.

Field identification & locations

The visible sandy texture and tan color are consistent with sandstone, but the image is insufficient to confirm it or identify its cement. A hand lens can reveal grains; common sandstone is found worldwide in sedimentary basins.
