Tropical karst (Chapter 15)

Introduction to karst. The word karst denotes a set of special landforms that develop mostly on carbonate rocks due to their high solubility. The rocks, however, do not dissolve uniformly, but mainly along lines of structural weakness such as joints or bedding planes. This happens both at the surface and inside the body of the rock.
