摘    要:舒哈迪铅锌多金属矿床赋存在发育于奥陶系中统多宝山组细碧岩、石英角斑岩岩系中的断裂构造蚀变带内,矿体呈脉状、透镜状,受舒哈迪背斜构造及其伴生的断裂构造控制,铅锌矿石成分简单,伴生有银和铜.围岩蚀变主要为黄铁矿化、硅化、绿泥石化、绿帘石化、绢云母化和碳酸盐化,具有不明显的分带性.成矿物质来源于奥陶系中统多宝山组变质岩系,成矿热液来源于隐伏的岩浆侵入体,矿床成因属于岩浆热液充填(脉)型铅锌多金属矿床,矿床形成时代为燕山早—中期.

关 键 词:铅锌多金属矿床  多宝山组变质岩系  岩浆热液  构造控制  热液充填(脉)型  内蒙古

Abstract:The Shuhadi lead-zinc polymetal deposit is located in the faulted structural alteration belt in the spilite and quartz keratophyre series of Middle Ordovician Duobaoshan formation.The ore bodies are controlled by the Shuhadi anticline and accompanying fault structure,occurring in veins or lens.The composition of the Pb-Zn ore is simple,associated with Ag and Cu.The wallrock alteration types involve pyritization,silicification,chloritization,epidotization,sericitization and carbonation,showing inconspicuous zonation.The ore-forming materials come from the metamorphic rock series of Ordovician Duobaoshan formation,with hydrothermal ore-forming solution from latent igneous intrusions.The deposit genetically belongs to magmatic hydrothermal filling type of lead-zinc polymetal deposit,in forming age of Early-Middle Yanshanian.
Keywords:lead-zinc polymetal deposit  metamorphic rock series of Duobaoshan formation  magmatic hydrothermal fluid  structural control  hydrothermal filling type  Inner Mongolia
