AB During diagenesis, several reactions induce changes both in phyllosilicates and organic matter, which in basinsassociated to the production of hydrocarbons leads to ammonium fixation in illite and micas [1] and to dissolutioninduced by organic acids [2] [3]. Dissolution processes may contribute to the smectite-to-illite transformation,stabilized by fixation of K (and NH4+). Ammonium is a weak acid in solution. Under neutral conditions where theconcentration of hydronium is very low (<10-7 M), ammonium contributes to smectite dissolution. The effect oforganic acid on silicates dissolution is partially known, but the potential role of ammonium is completely novel.
