Physical properties
Hardness varies from 6 to 7 based on clast composition, typically brown to reddish-orange, dull luster, composed of rounded pebbles cemented by finer matrix.
Formation & geological history
Formed by the consolidation of rounded gravel and boulder-sized clasts in high-energy environments like river channels or beach fronts.
Uses & applications
Used primarily in construction aggregate, road base material, and occasionally as decorative facing stone.
Geological facts
Conglomerates provide direct evidence of past high-energy water environments and can preserve ancient riverbeds.
Field identification & locations
Easily identified in the field by its characteristic pebble-in-matrix texture; found globally in sedimentary basins.
