Active or recently-active, large-scale quarrying operations within the Carboniferous Limestone Series of this area, and ranging in location from the near-junction areas to points about half a mile removed from the southern boundary of the main littoral Trias outcrops, have afforded excellent sections displaying remnants of a former Triassic cover. It is considered unlikely that the latter outliers, of limited dimensions, occur in areas further removed than about one-third of a mile south of the existing limits of the main Triassic outcrops.
