摘要：
In order to reveal the geochemical characteristics of rare earth elements in Karst groundwater in Heqing basin, the conventional indexes and REE tests of main Karst springs and groundwater samples in the basin were conducted. The quality concentration, distribution mode, differentiation characteristics and influencing factors of rare earth elements in groundwater in this area were analyzed and studied. The results showed that the quality concentration of the total rare earth element in the eastern part of the basin is higher than that of western Karst groundwater due to the different water bearing rock groups. The concentration of the total rare earth element in Karst groundwater in this area is negatively correlated with Eh, HCO3-, Ca2+, and has a good positive correlation with pH, dissolved oxygen, Fe and Mn. The high content of HCO3- and Ca2+ restricts the dissolution of REE in water, and the iron manganese content is negative correlation with pH, DO, Fe and Mn. The reductive dissolution of oxide minerals is the main way for REE to enter groundwater. LREE in groundwater is rich and or some has losses, and some of them are neither enriched nor lost. The concentration of HREE in the groundwater in the eastern part of the basin is much higher than that in the western region. The Karst groundwater in this area shows obvious negative Ce anomaly and positive Eu anomaly, which may be related to the lithology and reduction environment of water bearing rock formation. At the same time, Eu2+ is more likely to be released into groundwater in the environment with high Ca2+ and HCO3-. In the underground river pipeline, the mass concentration of ∑REE at the outlet of the underground river is higher than that of the Karst spring after a long distance of underground runoff. Compared with the inlet, the enrichment of LREE and the positive anomaly of Eu in the outlet groundwater are enhanced, and the negative anomaly of Ce is reduced. Compared with the groundwater in the outlet of Karst spring river, the REE concentration in the outlet of Karst spring river is slightly higher than that in the outlet of Karst spring river. © 2021, Editorial Office of Journal of the Chinese Society of Rare Earths.
