Abstract
Zuosikong lead-zinc mine is located in the polymetallic deposit of the Kangdian axis,the southwestern margin of the Yangtze platform,the movement of the regional structure is strong,the magmatic activity is frequent,the structural feature is complex,it has a certain genetic relationship with"Dahongshan type"iron and copper mine,it has features of volcano plume-sedimentary facies belt and marginal facies.The third lithologic section of the"Dahongshan type"Hongshan group,the Manganghe group eroded completely because of multi-stage tectonic movement in this area.Unconformity breccia mainly contains sericite,muscovite,quartzose fine conglomerate,coarse-grained lithic sandstone and iron-enrichment mainly shows in the form of limonite.关键词
