Sediments containing over 30% gravel that become lithified into solid rock are termed conglomerate. Conglomerates are widely distributed in sedimentary rock of all ages, but usually as a minor component, making up less than 1% of all sedimentary rock.

These include conglomerates of the Triassic basins of eastern North America and the New Red Sandstone of south Devon.
