| Geochemical Characteristics of Rare Earth Elements in the Water Body of the Ganjiang River, Southern Jiangxi |
| Concentrations of dissolved rare earth elements(DREE) were measured in the upper reaches of the Ganjiang River in southern Jiangxi Province.The authors analyzed the distribution and fractionation of DREE in the water,and discussed the origins of the rare earth elements(REE) signatures.The results show that Ce has negative anomalies in the valley of southern Jiangxi,suggesting less mobilization of Ce in the weathering profile.The water controlled by natural weathering has no obvious REE fractionation except for Ce and Eu.The positive Eu anomalies in this area are mainly determined by the preferential dissolution of Eu-enriched minerals.The DREE in the water affected by the evaporable salt deposit are lowly fractionated in comparison with those in the natural settings.The heavy REE(HREE)-enriched negative Eu anomalistic patterns in the water body affected by rare earth deposit have inherited characteristics of the weathering crust.Middle REE(MREE)-enriched negative Eu anomalistic patterns in the mainstream water are probably related to anthropogenic factors. |
