Physical properties
Hardness typically varies between 6 and 7 depending on mineral content; gray-brown color with dull luster and rounded, smooth texture.
Formation & geological history
Formed through mechanical weathering and subsequent fluvial transport, smoothing sharp edges over long periods in dynamic water environments.
Uses & applications
Used primarily in landscaping, decorative ground cover, and general aggregate construction.
Geological facts
Pebbles are officially classified by geologists based on size, typically ranging from 4 to 64 millimeters in diameter according to the Krumbein phi scale.
Field identification & locations
Found abundantly in riverbeds, lake shores, and ancient conglomerate formations; identified by its rounded shape resulting from continuous water tumbling.
