Western part of Burgundy and southern part of the Paris basin, the Nivernais karst takes from these 2 regions their lithologie and structural features : middle and upper Jurassic carbonate formations, monoclinal structure with horsts and grabens. But its particularity is in the thick superficial formations, that are supporting a wide mantle of forest , and that condition its morphology, its hydrodynamic and its hydrochemistry. The karst area is distinguished by closed depressions and by the abundance of valleys. The penetrable cavities are scarce and of a little extension, and are principally underground streams. The study of the hydrodynamic and of the chemistry of some springs has shown the complexity and the variability of the working of...
