DescriptionRed Wharf Limestone Formation, Red Wharf Bay, Anglesey, North Wales, UK.jpg
English: Sequence through the Serpukhovian Red Wharf Limestone Formation. A marine limestone at the base of the cliff is overlain by an orange coloured fluvial sandstone. Subaerial exposure of the limestone during a period of falling sea level resulted in the formation of a karstic surface, which has then been infilled by the river sands. A thin, estuarine silty mudstone overlays the sandstone, which is turn overlain by a second marine limestone.
