Impact of SO2 on Alteration of Reservoir Rock with Ca-Deficient Conditions and Poor Buffering Capacity under a CO2 Geologic Storage Condition

<div>SEM electron backscatter images of precipitated secondary minerals by SO2-CO2-water interaction in the experiments: (a) kaolinite in pure CO2 case, (b) kaolinite in 0.1% SO2 case, (c) mixed clay minerals in 0.1% SO2 case, and (d) pyrite in 1% SO2 case.</div>
