Summary:The distribution of REE in surface and groundwaters associated with undisturbed Zn-Pb massive sulphide deposits and active mines in the Bathurst Mining camp, New Brunswick, is controlled by pH, redox conditions, the formation of stable REE-carbonate complexes, the adsorption of LREE to colloids and fracture zone minerals and the precipitation of REE phosphate minerals. Surface waters have negative Ce anomalies due to the oxidation of Ce3+ to Ce4+ and the preferential removal of Ce4+ from solution. The oxidation process is rapid as seeps adjacent to these streams often have no Ce anomaly. [M.E.H.]
