摘　　要：纳木错-嘉黎断裂带是以铜、铅、锌为主的多金属成矿带,矽卡岩型矿床是该区带典型矿床类型之一。在总结矿床地质特征基础上,从成矿物质来源、成矿物理化学环境及成矿时代等方面探讨了矿床成因,认为拉屋铜-锌多金属矿床是与燕山晚期岩浆活动密切相关的矽卡岩型矿床,并建立了矿床成矿模式,对今后该区带的找矿工作具指导意义。Namuchuo-Jiali fracture zone is a polymetallic ore zone where copper, lead and zinc ores are the main types of ores and skarn type ore deposit is the typical ore deposit species. The paper discusses ore genesis form the view of ore mater origin, ore forming physical-chemical environment and the metallogenic ages based on the summarizing of ore deposit characters. The lawu copper-zinc polymetallic ore deposit is thought to be the skarn type of deposit closely associated with the magmatic activities of late Yanshanian period and has established the metallogenic model of the ore deposit, which is significant to guide the exploration in the area.
