Light Hydrocarbon Geochemistry of Oils in the Alpine Foreland Basin: Impact of Geothermal Fluids on the Petroleum System

Figure 10

Cross-plots of δ²H [V-SMOW] versus δ¹⁸O [V-SMOW] values. Average isotopic values of Malmian aquifer are indicated after Andrews et al. [7], Goldbrunner [6], and Elster et al. [26]. For sample location, see Figure 1(c). According to Andrews et al. [7] and Goldbrunner [6], the regression line represents the mixing of connate brines and Malmian water.
