aMeasured at room temperature. bMagnesium and silica precipitated from the solution at 25°C. Initial gravimetric concentrations are Mg = 4.5 × 10-3 mol/kg-solution and Si = 7.8 × 10-3 mol/kg-solution for Leg3 and are Mg = 6.0 × 10-3 mol/kg-solution and Si = 5.9 × 10-3 mol/kg-solution for Leg4. cNot analyzed. dNot detected, detection limits: F = 0.25 ppm, HCO3 = 1 ppm. | |||||||||
