The Hydrogeochemical Stratigraphy of Brines and Its Implications on Water Management in the Central Jordan-Dead Sea Rift Valley, Israel

Figure 6

Cross plots of elements and element ratios indicating mineralogical processes. (a) Dissolution of halite or dilution of brine with freshwater. (b) The slope of the Mg²⁺ vs. Ca²⁺ plot with 0.17 is in the range of equilibria with dolomite. (c) Albitization of plagioclase. (d) Cross plots of Ca²⁺ vs. SO₄^2- reveal that three different trends: (i) dissolution of gypsum, (ii) sulfate dissolution, and (iii) bacterial sulfate reduction. Ratios are based on meq/l.
