La zone d'oxydation se trouve entre la surface du sol et le niveau hydrostatique des eaux d'infiltration. Dans cette zone, les gisements sont en général appauvris de beaucoup de minéraux métalliques par l'effet du lessivage. Les constituants ferrugineux, et avant tout la pyrite, minéral dominant dans la plupart des gisements sulfurés, se transforment en limonite, sur place ou avec une certaine migration. 5, record 1, French, - zone%20d%27oxydation
