中文摘要: 云南羊拉铜矿床为金沙江铜多金属成矿带内最为典型的铜矿床,其矿体明显受构造控制,研究深部中段的构造特征、总结构造控矿规律成为找矿预测的有效手段。本文以羊拉矿床的3175m中段为研究对象,对其构造(断层、节理)进行了详细调查、描述。结果表明:羊拉矿床经历了近南北向构造带→早北东向构造带→晚北东向构造带→北西向构造带的四期构造运动,分别对应海西期、印支期、燕山期、喜马拉雅期,而成矿构造为印支期早北东向构造带。依据成矿地质条件和构造控岩控矿规律,本文提出了三个找矿预测靶区:28#勘探线北西侧、10#勘探线西侧、11#勘探线西侧。
Abstract:The Yangla copper deposit is one of the most important copper deposits, which locates in the central part of the Jinshajiang metallogenic belt. The ore bodies were strictly controlled by structure. It has become an effective means of ore prospecting prediction to study the structural characteristics and summarize the regularity of ore-controlling structure. In this paper, the 3,175m level tunnel of Yangla Cu deposit was investigated and described in detail for its structure (faults and joints). According to the results of this study, the Yangla copper deposit has undergone four stage structure activities. Since the nearly SN structure belt →Early NE structure belt →Late NE structure belt →NW structure belt, which corresponded to Hercynian, Indo-China, Yanshanian and Himalayan respectively, and the ore-related structures are early NE structure belt in Indo-Chinese Epoch. Three prospecting prediction target area were proposed in this paper which based on the metallogenic geological setting and the regularity of ore-controlling structures: northwest of No.28 # prospecting line, west of No.10 # prospecting line, west of No. 11 # prospecting line.
