The long-term redis.ribution of Zn in a naturally Zn-enriched s.il during pedogenes.s.was.quantified bas.d on mas. balance calculations. According to their fate, parent limes.ones.compris.d three Zn pools. bound to calcite and pyrites.halerite grains. bound to phyllos.licates.and bound to goethite in the inherited phos.hate nodules. Four pedological proces.es. i.e., carbonate dis.olution, two s.ages.of redox proces.es.and eluviation, redis.ributed Zn during pedogenes.s. The carbonate dis.olution of limes.ones.releas.d Zn bound to calcite into s.il s.lution. Due to res.dual enrichment, Zn concentrations.in the s.il are higher than thos. in parent limes.ones. Birnes.ite, ferrihydrite and goethite dis.ers.d in s.il horizon trapped high quantities.of Zn during their formation. Afterwards. primary redox conditions.induced the releas. of Zn and Fe into s.il s.lution, and the s.bs.quent individualization of Fe and Mn into Zn-rich concretions. Both proces.es.and s.bs.quent aging of the concretions.formed induced s.gnificant exportation of Zn through the bottom water table. s.condary redox conditions.promoted the weathering of Fe and Mn oxides.in cements.and concretions. This.proces. caus.d other los.es.of Zn through lateral exportation in an upper water table. Concomitantly, eluviation occurred at the top of the s.lum. The lateral exportation of eluviated minerals.through the upper water table limited illuviation. Eluviation was.als. res.ons.ble for Zn los., but this.Zn bound to phyllos.licates.was.not bioavailable.
