Geochemical approach of the Sebou watershed thermal waters, Morocco
Sebou watershed is characterized by springs with widely different mineralization (TDS vary from 511.7 mg/l to 29254.8 mg/l). New oxygen(18O)and hydrogen (2H) isotope data indicate that these waters result from meteoric water infiltration in the Middle Atlas and Rif mountains, circulating at shallow depths in sedimentary rocks. A SiO2-temperature plot of all the spring data shows that silica values fall around the quartz and chalcedony solubility lines, so they are undersaturated with respect to cristobalite and amorphous silica at these temperatures. The waters are in equilibrium with dolomite in carbonate-rock systems and kaolinite in silicate-rock systems.
