Figure 4

(a) Cl versus Cl/B of the thermal waters for the studied areas. The arrows indicate water–rock interactions. Equilibration water–rock line is depicted (shaded area-the edge points represent the interaction of thermal water with the aquifer matrix). (b) Li/B versus 50*B/(50*B + Cl) of the thermal waters. The rectangular shapes represent the ratios of Andesitic and Rhyolitic rocks.
