Formed in the early-Triassic, it is part of the Narrabeen Group of sedimentary rocks. This formation includes medium to coarse-grained sandstone and conglomerate. With minor amounts of siltstone and claystone. Below the Munmorah Conglomerates are Newcastle Coal Measures, originating from the Permian.[1][2]
