Formation & geological history

Formed through the weathering and erosion of larger rock formations, transported by water or wind. Found globally in alluvial deposits, riverbeds, and as garden gravel.

Uses & applications

Used primarily for landscaping, construction aggregate, and as driveway gravel. No significant jewelry or individual collection value.

Geological facts

Small pebbles like this are indicators of local geological history, often transported miles from their original source by glacial or fluvial processes.

Field identification & locations

Identify by its light color and grainy texture. Common among driveway or garden mulch materials. Acid test (fizzing with vinegar) can distinguish if it is limestone.
