West side of Hook Head
Carboniferous Porter's Gate formation sandstones of the near shore beach to barrier setting that grades coarse to finer cross bedded sands and shales into carbonates. Some the carbonates are fossiliferous mudstones that are inter bedded locally with shale to siltstone of an offshore shelf setting. These sediments were subjected to wave sorting and rippling! This section shows evidence of faulting which causes the section to be repeated!
