Laterally adjacent to and interfingering with the 
biostromal limestone is an archaeocyathan-rich biosparite indicating rewroking and deposition as lenses along side the bistromal growths. The siltstones/shales above and below the biostrome are lacking archaeocyathan.
The assemblage is found in a biostromal limestone with a boundstone fabric in which micrite mud surrounds the fossils. the formation consists of interbedded sandstone and shales with occasional bedded and/or lenticular limestone.
