Likely quartz-rich sandstone

Quartz arenite (tentative; exact identification is not possible from the image alone)

AI-generated identification · may be incorrect

Small, tan, angular fragment with a dull, granular surface. If sandstone, it is mainly quartz (Mohs 7) grains cemented together; hardness and cleavage cannot be confirmed visually.

Physical properties

Small, tan, angular fragment with a dull, granular surface. If sandstone, it is mainly quartz (Mohs 7) grains cemented together; hardness and cleavage cannot be confirmed visually.

Formation & geological history

Sandstone forms when deposited sand is compacted and cemented, commonly in river, beach, or desert settings. Its age cannot be determined from appearance alone.

Uses & applications

Sandstone is used as building and paving stone, aggregate, and decorative material; this small fragment has little practical or commercial value.

Geological facts

The image shows a pale, granular rock fragment, but its grain size and cement are not clear enough to distinguish sandstone confidently from other rocks.

Field identification & locations

Look for visible sand-sized grains and a rough, gritty texture; a fresh surface or hand lens helps. Similar rocks occur worldwide in sedimentary basins.
