(geology) deposits of mixed oxides and hydroxides of iron formed when iron-bearing groundwater emerges onto the surface
Typical iron-bearing groundwater emerging as a spring. The iron is oxidized to ferric hydroxide upon encountering the oxidizing environment of the surface. A large number of these springs and seeps on the flood plain provide the iron for bog iron deposits.
