摘　　要：华南地壳物质架构、巨型金属成矿系统及典型的钨矿化特征。利用锆石Hf同位素填图技术首次从大陆尺度刻画出华南古老、再造和新生地壳并置的空间架构,揭示了与花岗岩相关的W-Sn-Nb-Ta和REE矿床产于再造地壳域,其中,REE矿床产于有较多新生幔源物质注入的强再造地壳块体中。Cover Story:Crustal architecture,giant metal ore systems,and typical tungsten mineralization features.The continental-scale crustal architecture of the spatially juxtaposed ancient,reworked,and juvenile crustal domains of South China was imaged for the first time using zircon Hf isotopic mapping.Granite-related W-Sn-Nb-Ta and REE deposits occurred in reworked crustal domains,and REE deposits occurred in strongly reworked crustal blocks with juvenile input.
