江西武山块状硫化物矿石表生风化过程中稀土元素地球化学行为 总被引:3,自引:1,他引:3
The behavior of REE during the sulphide weathering is still poorly understood, although REE geochemistry during weathering of igneous rocks has been well documented, in this study, the REE contents of primary sulphide and their weathering products (gossan) of the Wushan copper mine were investigated. The mobility of REE in the weathering profile of sulphide is limited, with the majority of REE retained in the gossans. However, REE are fractionated in the weathering process, with HREE relatively enriched in the gossan samples. Ce is depleted in the gossan, whereas the difference of Eu anomaly of the gossan and primitive sulphide is neglectable. 相似文献
