If all the clasts are the same type of rock or mineral), the rock is categorized as monomictic conglomerate. If the clasts are made up of two or more rocks or minerals, the rock is a polymictic conglomerate. The size of the clasts. Rock comprised of large clasts is cobble conglomerate.The most common chemical sedimentary rock, by far, is limestone.
