Abstract:

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.

Key words: lead-zinc deposit, REE, ore-forming materials, hydrothermal deposits
