Pebbles are a naturally occurring map tile found commonly across the surface of the world near rivers and brooks, and occasionally as beaches. Usually they are found labelled as rock-type pebbles, for example Basalt Pebbles. They can be found near boulders if you look hard enough.
Unlike boulders, pebbles cannot currently be designated for smoothing. In order to smooth a tile with pebbles on it, you must first build a road or other construction on the tile, which will destroy the pebbles and turn the tile into an ordinary tile of the base rock-type.
In Adventurer mode, a pebble tile is an unlimited source of small rocks, which can be useful for throwing.
