A soil-forming process that occurs under prolonged waterlogging, where the near-absence of oxygen causes iron compounds in the soil to be chemically reduced, producing the grey, blue-grey or mottled coloring characteristic of gleyed soils. It is typical of poorly drained lowlands, wetlands and areas with a perennially high water table.
