The word exokarst is used to refer to all the surface relief features generated by karstification.
The Sorbas Gypsum Karst is characterised by the enormous number of dolines present, the variety of karren, the tumuli and the presence of a scarp along the edge of the gypsum outcrop. All these relief features are related to the karst (Figures 1 and 2).
