dc.description.abstract | Groundwaters hosted within unconfined aquifers were collected from sixty-five cold and slightly thermal springs and wells. The studied aquifers are mainly constituted of a thick sequence of carbonates, Meso-Cenozoic in age. Basic volcanic intercalations, occurring during several episodes, are also present. Except for the samples located near the coast where seawater contribution plays an important role, the chemical composition of studied groundwaters is controlled by water-rock interaction. The proposed geochemical mass balance model suggests that Ca+Mg/HCO3 groundwaters evolve toward a Na-HCO3 type due to interaction with volcanic rocks, thus forming secondary minerals. pCO2 values up to 0.1 atm suggest a contribution of a CO2-gas source. The 13CTDIC values range between –15 to -8 ‰ vs PDB, indicating mixed organic-inorganic carbon sources. | en |
