This picture shows a cliff of Carboniferous Oolitic Limestone in a disused quarry. The upper surface was kartsified in the Carboniferous with a thick soil on top. The dissolution of the carbonate has left a thick wedge of regolith on top. Note the castellated boundary between the dark grey oolite and the yellow-coloured regolith.
