| 摘 要： | 丹巴燕子沟金矿床地处我国重要的金矿成矿区-川西地区,已有较长的民采历史。在总结其地质特征的基础上,通过对控矿构造、含矿岩系及成矿作用的研究,认为构造对该地区矿床的形成、富集、产出起着主导作用。矿区构造对金矿体的控制主要有两种类型:一是由脆性断裂控制的石英脉型金矿体;二是由韧性剪切带和滑覆构造所控制的碳质板岩型金矿体。而矿区构造的"断层阀-地震泵吸"成矿机制也是该金矿形成的重要原因。

| Abstract: | Yanzigou gold deposit was located in the west Sichuan,which was the important metallogenic province of China,had long history of non-government exploitation.Based on the summarization on the geologic characteristics of gold deposit,through the studies on the ore-controlling factors,on the ore-bearing rock series and metallogenic mechanism,the authors inferred that the structure was the main factor for the formation,enrichment and output of gold deposit.There were two types of ore-controlling structures for ... |
