Abstract

Groundwaters from two important lithological units of the Archaean complex consisting of schists and granite gneiss were analysed for major cations and anions. The cation and anion relation with respect to total dissolved solids suggests atmospheric precipitation, rock dominance and evaporation as the mechanisms that control the chemistry of groundwaters.

The groundwater from schistose aquifer is less saline as compared to water from granite and granite gneiss aquifer.
