Hydrogeological characteristics of the Chaîne des Puys are linked with its climatic, geological, morphological and environmental characteristics. These specifities constrain origin, quantity quality and flow of water in volcanic aquifers. As the chemical and isotopic signatures of water reflect processes occurring during the water cycle, their variations into and between the various compartments specifies the role of these factors. The subject of this thesis deals with the chemical (major ions) and isotopic (δ18O, δ2H, δ13C) characterization of different stages of the water cycle to define the operation of sub-volcanic aquifers of the Chaîne des Puys. In this perspective, this work focused on two themes: 1) the definition of the input signa...
