Temporal evolution of the saturation indices of selected minerals and stilbite in the reactive fluids including (A) carbonate minerals, (B) stilbite and other zeolites and (C) selected clay and Al-hydroxide minerals. These saturation indices were calculated using PHREEQC50,51 together with its “Kinec.dat” database43,53. A positive saturation index indicates the mineral is supersaturated in the fluid, whereas a negative saturation index indicates the mineral is undersaturated in the fluid.
