中文摘要：

文章在分析扬子地块西南缘与前寒武纪铜多金属矿床成矿特征及与有关的重大地质事件的基础上,研究了区域成矿作用与重大地质事件的响应,划分了区域金属成矿系列,较详细地论述了主要成矿系列的组成及成矿规律,总结了扬子地块西南缘前寒武纪铜多金属矿床及成矿系列。认为本区成矿作用属于多期次成矿,至少可以分为前期预富集作用及两次大的成矿作用（古元古代成矿作用和中元古代成矿作用）,以及若干个小的成矿作用;1.7Ga—1.5Ga、1.1Ga—1.0Ga、中新生代是3次规模、强度较大的铜矿成矿作用,形成了研究区内规模较大的诸多铜多金属矿床。

英文摘要：

Based on analysis of metallogenic characteristics of the Precambrian Cu polymetallic deposits at southwest margin of Yangtze block and related significant geological events the regional metallogenesis and response of the significant geological events are dealt with in the paper and the regional metal metallogenic series divided, the main metallogenic series and regularity detailed and summarized in the paper. The metallgenesis is at least divied into two major periods, the pre-enrichment during Early proterozoic Era and Late Proterozoic Era （1.7 Ga-1.5Ga、1.1 Ga-1.0Ga） and the main enrichment during Mesozoic-Cenozoic Era and several weak metalogenic stages. During Mesozoic-Cenozoic Era 3 strong metallogenic stages in large scale occur and many large Cu polymetallic deposits formed in the study area.
