The rare earth elements (REE) along with iron and manganese distribution in ochre-precipitates wetland soils a passive system for acid mine drainage treatment (Jales, Portugal) was studied. results obtained by instrumental neutron activation analysis showed higher incorporation of the light REE (particularly La Ce) resulting from water-limestone interaction. These fluffy materials influence entrance first where correlation between Fe Ce found. Then Mn phases appear to play more important role controlling remaining area soils.
