Figure 11: Correlation statistics of relationship of cations and anions in 22 brine samples, Dukhan Sabkha (a and b showed good relationship between Na+ and Cl, and between Cl- and Mg.2+ TDS gives good relationship with Na+,Cl- and Mg+ as in d, e and f. Relatively good relationship found between SO4 2- with Mg+ and TDS with SO4 2- and with Mg2+/Ca2-as in c, g and h respectively).
