- W3206813061 abstract "located in southern Saskatchewan, Canada. The groundwaters are Na-Mg-SO{sub 4}-type waters that range from highly concentrated brines near the ground surface to relatively dilute waters at depth. The majority of these groundwaters have pH values between 7 and 8, although the deepest samples are more alkaline. Groundwater REE concentrations are relatively constant in the overlying till but increase by up to a factor of 50 in the underlying clay bedrock. Shallow groundwaters have heavy REE (HREE)--enriched shale-normalized patterns, whereas the REE patterns of the deep groundwaters are relatively flat. Solution complexation modeling indicates that variations in REE patterns reflect differences in solution complexation across the REE suite. In the shallow groundwaters, strongly adsorbed, positively charged carbonate complexes, sulfate complexes and free metal ion species dominate the speciation of light REEs (LREE), whereas HREEs occur chiefly as more stable, negatively charged dicarbonato complexes. For the deepest groundwaters, however, all of the REEs are predicted to occur in solution as dicarbonato complexes. The large HREE enrichments of the shallow groundwaters reflect the greater affinity of the positively charged LREE solution species to adsorb to clay minerals or coatings on clay minerals in the aquitard sequence compared to the more stable, negatively charged HREE dicarbonato complexes. On the other hand, the flat REE patterns, of the deep groundwaters reflect the dominance of the negatively charged dicarbonato complex for all REEs. The solution complexation model along with the strong positive correlation between REEs and to a lesser extend pH, indicates that carbonate ion concentrations, and thus pH, exert important controls on aqueous REE concentrations in these groundwaters." @default.
