Reverse weathering generally refers to a process of clay neoformation consuming cations and alkalinity in a way unrelated to the weathering of silicates. More specifically reverse weathering refers to the formation of authigenic clay minerals from the reaction of 1) biogenic silica with aqueous cations or cation-bearing oxides or 2) cation poor precursor clays with dissolved cations or cation-bearing oxides.
