Sur l'origine des gradients de teneurs isotopiques et géochimiques dans les eaux karstiques du Jura (France)

Auteur :

Description :
Titration of isotopic and geochemical ratios in karst water of the Jura Mountains shows gradients at the groundwater province scale. Climatic gradients are displayed under consideration of the emergence water temperature and its O content (0.225/oo per 100m). Geochemical gradients are connected to the intake area lithology (limestones, marls, dolomites) but are also influenced by pollution. Gradients connected to the hydrodynamics (ionic activity, silica, tritium) oppose quick transit to long stay aquifers.
