摘　　要：铜厂铜铁矿、东沟坝金银铅锌多金属矿、柳树坪铁、金铅锌三个不同组合多金属矿床,其赋矿层位(阳坝岩组、灯影组)及岩性不同且具一定成矿系统专属性,与区内地层岩性、构造岩浆演化相耦合,其沉积环境、火山机制、构造岩相及矿床成矿系列空间展布共同构成区内一套成矿系统。本文通过分析三个典型矿床的聚集与演化规律,并结合区内构造、岩浆事件的成矿(蚀变)年龄数据作支撑,对其成矿作用进行思考和总结。There are three different combinations of polymetallic deposits,Tongchang copper-iron deposit,Donggouba gold-silver-lead-zinc polymetallic deposit and Liushuping iron-gold-lead-zinc polymetallic deposit,occurring in different ore-bearing horizons(the Yangba rock formation and the Dengying Formation)with different lithology and however they have a certain metallogenic system specificity coupling with regional strata,lithology,tectonic and magma evolution.Their sedimentary environment,volcanic mechanism,tectonic lithofacies and ore metallogenic series in space distribution together constitute a set of metallogenic system in the area.Based on the analysis of the accumulation and evolution of three typical deposits and the data of tectonic and metallogenic(alteration)age data of magmatic events in the area,the metallogenesis of these deposits is discussed in this paper.
