Reactive Transport Modelling of Elevated Dissolved Sulphide Concentrations in Sedimentary Basin Rocks

Figure 10

Comparison of the mean of simulated concentrations of HS^- (a), O_2(aq) (b), SO₄^2- (c), and Fe²⁺ (d) at different depths for the reference case (BASE) with sensitivity cases S1, S2, and S3. Simulated concentrations were extracted from the subregion depicted in Figure 3, excluding data points in the crystalline basement rocks (G and Gw).
