I want to create a plot, as given in the figure below (Hurowitz and McLennan, 2007), where the minerals will react with a known fluid composition in different water-to-rock ratios. However, I am unable to find the way through which such a reaction model can be performed. Any help in this regard would be highly appreciated. I have also attached a reaction file where a known acidic water is reacting with two minerals present in a system at 5:1 water-to-rock ratio (if I understand the system correctly). Surprisingly, no secondary minerals are forming in this reaction model. Except SiO2 (aq) all the other values of the initial fluid are known.
