?Photo 25. Steeply dipping layers of Namurian to Westphalian age sandstones, siltstones and shales at Monkstone Beach, between Saundersfoot and Tenby, south Pembrokeshire. As in the previous photo, these sediments were originally laid down sub-horizontally in fluvio-deltaic to shallow marine environments on the southern margin of the Wales-Brabant landmass, but they were uplifted and folded to almost vertical orientations by the Late Carboniferous to Early Permian Hercynian/ Armorican Orogeny, produced by the collision of the Gondwanan and Laurentian continents.
