Caption

These outcrops consist of Upper Triassic sediments from the Mercia Mudstone Group thought to have formed in a mixed floodplain and playa origin environment (Talbot et al. [12]). A) This cliff outcrop contains nodular sulfate and clay mixtures toward the base (arrowed) and pure gypsum veins in the mid part of the cliff. Cliff height 30 m. Scale bar is 1 m. B) White gypsum veins derived by partial dissolution of sulfate-rich deposits formed by near-surface evaporation. SD sandstone dyke, Gy and clay gypsum nodule. Scale bar is 0.5 m. C) Pure gypsum veins (some with orange coloration) in gray mudstone member of Watchet Triassic mudstone. Scale bar is 0.25 m.
