摘　　要：里伍铜锌矿田是扬子地台西缘众多铜矿中典型而又独特的一个大型铜多金属矿田。里伍铜矿床自1958年勘探开发以来已历经50余年,逐渐步入危机矿山阶段。以里伍铜锌矿田为研究对象,在系统总结前人资料的基础上,以现代成矿理论与矿田构造理论为指导,通过对矿田控矿构造解析研究,深度探讨了构造与成矿之间的关系,将里伍铜锌矿田控矿构造划分为三级:背形构造、环状剥离断裂构造、片理构造。在总结分析里伍铜锌矿田成矿地质背景、控矿地质条件、矿田成因和成矿规律的基础上,构建了矿田成矿模式,并进行了隐伏矿体预测。Liwu Cu-Zn ore filed is a typical but unique one of the large number of Cu-ploymetallic ore filed in the western margin of Yangtze Plateform.Liwu Copper Deposit has been explored more than 50 years since 1958,and gradually went into the phase of the crisis mines.This paper focuses on Liwu Copper Deposit by summarizing the former research in the area,following the guidance of modern metallogenic and ore field structure theory.Based on the study about ore-controlling structure,this paper discusses in depth the relationship between ore-controlling construction and mineralization,dividing ore-controlling structure in Liwu Cu-Zn ore filed into three levels：antiformal structure,annular detachment fault,schistosity structure.The paper analyzes the mineralization geological background,geologic ore-controlling conditions,ore-forming factors and regularities of Liwu Cu-Zn ore filed.Based on that,the metallogenic model is established.The concealed ore body has also been predicted.
