Conglomerate is a sedimentary rock composed of cemented gravel. It consists of rounded to subangular fragments (larger than 2 mm in diameter) set in a fine-grained matrix of sand or silt, and commonly cemented by calcium carbonate, iron oxide, silica, or hardened clay; the consolidated equivalent to gravel. The stones in this formation have evidently been subject to heavy pressure since they are crystalized.
