摘　　要：繁昌火山岩盆地及其周边地区具有良好的铁铜多金属矿的成矿地质条件,本文基于1∶25000重磁调查成果,结合化探、遥感、地质等资料,建立了繁昌火山岩盆地及其周边地区的基本构造格架;结合铅锌矿典型矿床成矿特征,圈定了铅锌矿成矿远景区及靶区,并对铅锌矿进行了成矿预测。The Fanchang volcanic basin and its periphery have good geological conditions for formation of iron and copper polymetallic deposits.Based on the results of 1:25000 gravitational and magnetic survey,combined with geochemical exploration,remote sensing and geological data,the basic structural framework was constructed for the Fanchang volcanic basin and its periphery.Referring to the metallogenic features of typical lead-zinc deposits,the exploration prospects and targets were delineated,and a prognosis was made.
