Tumbled speckled pebble, likely marble or limestone

Calcite-rich carbonate rock; possibly impure marble (CaCO₃)

AI-generated identification · may be incorrect

Small rounded gray-white pebble with black patches and faint beige veining; dull to slightly waxy luster and fine-grained texture. Likely Mohs hardness 3–4; calcite-rich material should fizz with dilute hydrochloric acid or strong vinegar, though a weak reaction may indicate marble or dolomitic rock.

Physical properties

Formation & geological history

Probably a naturally water-rounded carbonate fragment, possibly derived from metamorphosed limestone. Carbonate rocks in the Antalya–Alanya region commonly formed in ancient shallow marine environments, with later uplift and weathering; exact age cannot be determined visually.

Uses & applications

Mostly a common beach or stream pebble and possible craft/tumbled stone; not generally suitable for jewelry or high-value carving. Carbonate rock is widely used for aggregate, lime, cement, and decorative stone when present in larger sound deposits.

Geological facts

The dark areas may be carbonaceous material, iron/manganese staining, or another mineral; they are not diagnostic of a specific rock without testing. Its rounded shape indicates transport or deliberate tumbling.

Field identification & locations

Likely regional carbonate pebble, consistent with widespread limestone and marble around southern Turkey. Test streak, acid reaction, and hardness; avoid relying on color alone, since weathering can produce the mottled appearance.
