Coastal erosion. Eroded sandstone cliff at Burton Bradstock,Dorset. This rock is composed of Bridport Sands sandstone interspersed with cyclical carbonate-cemented horizons. These hard layers formed when calcium carbonate precipitated from shallow water. The soft sandstone between these hard calcite-cemented bands erodes very easily giving the cliff face a banded appearance | |
