AbstractCharacterization of geochemistry and geothermometry of the groundwater from the Continental Intercalaire (CI) aquifer, one of the largest aquifers in the world, stretching over one million km(2) surface area shared between Algeria, Tunisia and Libya, was conducted in southeastern Algeria nearby the border with Tunisia. Thirty-two water samples were collected from boreholes to analyze the physicochemical parameters and stable isotopes (delta O-18((H2O)), delta O-18((SO4)), delta S-34 ((SO4))) and determine the origin of water mineralization of the CI aquifer. Water temperature was assessed using several geothermometers, such as cations, silica and SO4-H2O stable isotopes. The CI aquifer displayed a discharge temperature varying from 45 to 65.1 degrees C due to water circulation at deeper depths ranging from 1000 to 2200 m. The Results show that CI water contains high total dissolved solids (TDS) and neutral to slightly alkaline pH. The most frequent water types were Na-Cl-SO4 and Ca-SO4 indicating the geological formation nature of CI aquifer which is mainly composed of evaporites. The application of Na-K and Na-K-Ca geothermometers yielded unreliable temperatures. However, Na-Li geothermometer resulted in relatively plausible temperatures ranging from 74.69 to 147.83 degrees C. Quartz and CaSO4-H2O isotope geothermometer are the most suitable methods for temperature estimation, due to their attainment of equilibrium resulting in temperatures ranging from 62 to 93 degrees C, and validation by the multiple mineral equilibrium approach. The present study demonstrated a successful application of CaSO4-H2O isotope geothermometer in a low enthalpy (<100 degrees C) geothermal system. The results corroborate previous findings on the same CI aquifer at the Tunisian side and on carbonate-evaporite geothermal reservoirs. Furthermore, geothermal potential of the CI aquifer has been highlighted suggesting its use as a source of renewable energy which could be applied in heating greenhouses and/or generating electricity.
