Physical properties

Tan-brown, rough and granular, with a rounded, irregular shape. Hardness, luster, crystal structure, cleavage, and specific gravity cannot be reliably determined visually.

Formation & geological history

Likely a naturally weathered and transported pebble, rounded by abrasion in a stream, on a beach, or in sediment. Its rock type and geological age are undeterminable from the photograph.

Uses & applications

Small pebbles are used for landscaping, crafts, and collecting; this specimen has no identifiable specialized use.

Geological facts

The rounded outline suggests abrasion, but many rock types can become pebbles and look similar in a photograph.

Field identification & locations

A closer view of fresh surfaces, a hardness test, and streak or acid tests would help identify it. Pebbles occur in river and beach deposits worldwide.
