对江苏南京甘家巷矿区铅锌矿床不同类型岩石和矿石的稀土元素地球化学特征进行研究，探讨了岩石和矿石中稀土元素地球化学行为。结果显示：矿床中稀土元素的分布较为一致；甘家巷矿区稀土元素总量变化大，总体来看，稀土总量在铅锌矿石、底砾岩和粉砂岩中相对富集；在稀土元素配分模式图上，轻稀土相对富集，稀土配分曲线向右缓倾，轻稀土元素随原子序数的增加富集程度降低，重稀土元素分布比较平坦。相对较稳定；稀土元素地球化学特征指示甘家巷矿区为受F2断裂和不整合面控制的中低温热液矿床。

Through the REE geochemical characteristics research of the rocks and minerals which have different types in Ganjiaxiang lead-zinc mining area,Jiangsu Province,the REE geochemical behavior of rocks and ores were investigated.And the results show that the distributions of REE in ore deposit are consistent.Overall,the total REE is relatively enriched in Lead-zinc ore,basal conglomerate and siltstone.On the REE patterns,LREE are enriched,and the curve tilts to the right slowly.In addition,the enrichment degree of LREE would be reduced with its atomic number increasing,but the HREE is relatively stable.REE geochemistry characteristics indicates that the Ganjiaxiang lead-zinc mining is a medium-low-temperature hydrothermal deposit which controlled by the F2 fault and unconformity.
