Before revision: The reverse weathering process can involve many different anions and cations, but can likely be summarised in the following simplified reaction:Biogenic opal (SiO2) + metal hydroxides (Al(OH)4−) + dissolved cations (K+, Mg2+, Li+, etc.)
After revision: The reverse weathering process can involve many different anions and cations, but can be summarised in the following simplified reaction:Biogenic opal (SiO2) + metal hydroxides (Al(OH)4−) + dissolved cations (K+, Mg2+, Li+, etc.)
