The formation consists primarily of conglomerate, although at some localities there are minor interbeds of coarse-grained sandstone, shale, and coal.
The conglomerate is typically massive and consists of well-rounded pebbles, cobbles and boulders of white, grey and green chert, and white and grey quartzite, in a matrix of quartzose sand.
In some areas there are also minor pebbles, cobbles and boulders of limestone, dolomite, black argillite and, rarely, greenish volcanics.
The conglomerate and sandstone beds are cemented with silica, making them very hard and resistant to erosion, so they tend to form prominent outcrops.
