Fig. 6From: Pore-water evolution and solute-transport mechanisms in Opalinus Clay at Mont Terri and Mont Russelin (Canton Jura, Switzerland)Isotopic composition of sulphate in rocks, veins and pore-waters at Mont Terri. Fields are shown for marine sulphate during different geological periods (based on Claypool et al. 1980 and Balderer et al. 1991). Data for current pore-waters are from Pearson et al. (2003) and Müller and Leupin (2012)Back to article page
