Abstract
The joints named grykes (or grikes) are karst forms filled with detritic, soil material outwashed from overlying deposits. They were developed by dissolution as a result of the karstification process through several phases. Subsequently joints are brought from the freatic zone into the vadose zone due to changes in the subsurface water regime and circulation of fluids. During this process they change their shape due the influence of tectonics and penetrate downward into underlying limestones. Thus they are subsequently widened by dissolution and in the final phase filled up either with products of surface erosion or by roof collapse.
