Reverse Weathering

Reference work entry
DOI: https://doi.org/10.1007/978-1-4020-3995-9_485

A geochemical process whereby the chemical composition of a soil or other weathering system acquires an influx of elements such as Ca, Mg, Na and K that are normally lost during weathering. In effect, reverse weathering results in a chemical trend away from compositions within the system SiO 2-Al 2O 3-Fe 2O 3-H 2O, the residua system of weathering. Reverse weathering was first hypothesized by Garrels (1965), as a process that probably occurred in the oceanic environment.
