The Songliang lead-zinc deposit which is located in the Sichuan-Yunnan-Guizhou lead-zinc mineralization district, is in control of fault strictly. oft-com:office:smarttags" />Ore body hosted in siliceous dolomite of Dengying Formation, the No. 1 and No. 2 ore body are respectively controlled by the F5 fault and F6 fault. Metallogenic geological characteristics of Songliang lead-zinc deposit has been analyzed in this paper, it is suggested that this deposit has great metallogenic potential, the prospecting foreground of deep and periphery concealed mineral is well. Based on the study of geological characteristics, siliceous dolomite of Dengying Formation, NW trending shearing compressional faults with a smooth breaking section, medium-low temperature hydrothermal alteration can be used as criteria for ore prospecting. oft-com:office:office" />
