Summary:The main processes controlling geochemical evolution of ground- water in the basin-fill aquifer were identified using major-ion chemistry, mass-balance calculations, thermodynamic calculations, stable isotopes, and mineral identification. These processes are: 1) dissolution of volcanic tuff and tuff-derived basin-fill deposits; 2) cation exchange of Ca and Mg in the water for Na in clay minerals; 3) weathering of plagioclase to montmorillonite; 4) precipitation of zeolite minerals; 5) concentration of dissolved constituents by evapotranspiration; 6) dissolution of Cl and SO4 evaporative salts, and 7) precipitation of calcite.
