Ground-water reservoirs with stagnation brine, where liquid moves in the top layer only, come into existence in the course of natural salt leaching. Diffusion from the dormant liquid towards the flowing ground-water has to be considered as the driving force for the continuation of the leaching process. The following conclusions can, among others, be drawn: The natural salt leaching proceeds as present so slowly that, apart from residual hollows in the overlying rock, there are no temporal or spatial consequences in the way of terrain subsidence. Leaching is intensified when the hydrogeological regime is disturbed (mining drainage). When drainages stops, the original state is restored after a major period only. Gypsum leaching proceeds almost exclusively at the level and above of the fresh-water/salt-water interface. (l'A.).
