Results indicate that major ions in the infiltration water are meteoric in origin (évapotranspiration of rain water plus equilibrium with a soil Pc02 of TO 25 atm) but sequential dissolution of calcite and dolomite also occurs in an open system to C02. Moreover, because the low discharge rate of the drip water points, this water maintains long contact with the cave atmosphere before enough volume can be sampled for a complete analysis. Thus measured pH are strongly affected, so modeled pH are lower (even 0.3-0.6 pH-units) than those measured onesspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Drip watersHydrogeochemical modelingNerja CaveAndalusiajournal articleopen access
