Extended Data Fig. 8: Geochemical modeling of the process of dissolution-precipitation between nontronite and glauconite.

The right panels show the trend of Fe_tot (Fe²⁺, Fe³⁺) and K⁺ along the process. The models were performed at 293 K (a) and b)) and at 273 K (c) and d)). Since the concentration of the solution depends on the initial temperature, the course of salinity is different through the same evaporative process.
