Physical properties
Hardness varies from 6 to 7 depending on clast composition. Displays a multicolored, coarse-textured matrix with rounded gravel or pebble clasts embedded in finer sand or silt.
Formation & geological history
Formed by the consolidation and cementation of gravel-sized rounded sediments, typically in high-energy environments like rivers or beachlines.
Uses & applications
Used primarily in the construction industry as crushed aggregate for road base and concrete production.
Geological facts
The rounded shape of the pebbles indicates they traveled significant distances via water before deposition and lithification.
Field identification & locations
Easily identified by its distinct 'plum pudding' appearance containing visible rounded pebbles cemented together; found worldwide in sedimentary basins.
