摘　　要：阿舍勒大型铜锌矿是我国典型的海相火山岩块状硫化物(VMS)型矿床,赋存于阿舍勒盆地早—中泥盆世阿舍勒组海相火山-沉积岩系中。结合阿舍勒铜锌矿最新勘探成果,通过对阿舍勒铜锌矿床矿物组合分带、矿石构造分带及成矿温度分带的研究,在Ⅰ号矿体9~21线0 m标高以下划分出一走向近NS向的火山喷流通道并总结了成矿模型。最终划分出Ⅰ号矿体9~21线-200 m以下及Ⅴ号矿化蚀变带深部两处找矿靶区。The Ashele large-scale copper-zinc deposit is a typical volcanogenic massive sulfide deposit in China,which is hosted in the marine volcaniclastic-sedimentary sequence of the Early to Middle Devonian Ashele Formation.Based on the latest exploration results of Ashele Cu-Zn deposit,through the study of mineral assemblages zoning,ore structure zoning and metallogenic temperature zoning of Ashele Cu-Zn deposit,a volcanic vent with a north-south orientation is divided below the 0 m elevation of line 9-21 of No.1 orebody,and the metallogenic model is summarized.Finally,two prospecting target areas are divided,the first one located in below-200m elevation of line 9-21 in No.1 orebody,the other one located in deep of No.5 mineralization alteration zone.
