摘　　要：佐思孔铅锌矿是位于康滇地轴、扬子准地台西缘的多金属矿床,该区区域构造运动强烈、岩浆活动频繁、构造行迹复杂,与“大红山式”铁、铜矿形成具有一定成因联系,具有火山喷流-沉积相带边缘相特征。受区域多期次构造运动的影响,“大红山式”红山组、曼岗河组第三岩性段剥蚀殆尽,并形成三叠系不整合面。不整合面角砾岩主要为含绢云母、白云母石英砂质细砾岩及砾质粗粒岩屑砂岩,铁富集主要以褐铁矿形式出现。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.
