Physical properties
Hardness varies from 6 to 7 depending on clasts; colors are multicolored; dull to sub-vitreous luster; rounded gravel and pebble clasts embedded in a finer matrix of sand or mud.
Formation & geological history
Formed by the consolidation and cementation of gravel-sized rounded clasts in high-energy environments like fast-flowing rivers or beach zones.
Uses & applications
Used primarily as crushed stone for construction, road aggregate, and occasionally as decorative facing stone.
Geological facts
Conglomerates provide direct geological evidence of past high-energy water environments and ancient river channels.
Field identification & locations
Easily identified in the field by its distinct 'plum pudding' appearance of rounded pebbles cemented together; found globally in sedimentary basins.
