Physical properties
Hardness varies from 6 to 7 on the Mohs scale depending on mineral content. Colors range from white, grey, to multicolored with vitreous to dull lusters.
Formation & geological history
Formed through physical and chemical weathering of parent rocks, followed by water transport and rounding in riverbeds or glacial environments over millions of years.
Uses & applications
Widely used in landscaping, gardening, drainage systems, and construction aggregate.
Geological facts
Water-rounded pebbles often show a high degree of sorting and rounding depending on the distance they have traveled in river systems.
Field identification & locations
Identified by smooth, rounded edges and mixed mineral compositions; commonly sourced from river gravel deposits and glacial outwash plains.
