Abstract: Fuxingtun Ag-Pb-Zn Polymetallic Deposit,which is a continental facies volcanic-subvolcanic hydrothermal Ag-Pb-Zn Polymetallic Deposit,is located in the silver polymetallic metallogenic belt in the middle and southern section of the Greater Khingan Range.Metal minerals are mainly sylvanite,naive silver,freibergite,sphale-rite,galena,chalcopyrite,and so on;the gangue minerals are mainly rhodochrosite,siderite,quartz,feldspar,sericite,and so on.The ore textures are mainly subhedral-anhedral granular texture,metasomatic texture,and colloidal structure; the ore structures are mainly disseminated structure,brecciated structure,and veinlet disseminated structure.The ore bodies that are concealed and overall arch output mainly occur at the intersection of NE and NW trending faults and are hosted in volcanic breccia,rhyolite,rhyolite tuff,breccia tuff,sedimentary tuff of the upper Jurassic Manketouebo Formation.The discovery of the deposit has benefited from integrated geophysical and geochemical prospecting methods.Soil survey composite anomaly results show that Ag,Pb,and Zn anomalies are large in scale,high in inten-sity,and obvious in concentration.Meanwhile,the 1:10 000 induced polarization intermediate gradient survey shows that the ore body is characterized by low resistivity and high polarization.Large-scale Ag-Pb-Zn polymetallic ore bodies were found by drilling engineering to verify induced polarization anomalies deep in the deposit.The comprehensive geological analysis concludes that the ore bodies are controlled by a volcanic mechanism obviously,and that mineralization is closely related to volcanic-subvolcanic hydrothermal activity.The ore body output is controlled by the syngenetic fracture system derived from the volcanic structure and subvolcanic intrusion body.The discovery of the Fuxingtun Ag-Pb-Zn polymetallic deposit provides a new idea and direction for prospecting the same type of deposits in this area and the integrated geophysical and geochemical prospecting method adopted provides important exploration experience for further prospecting,which has great theoretical and prospecting significance.
