中文摘要: 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 located in the west Sichuan-the important metallogenic province of China, had long history of non-government exploitation. Based on the summarization on the geologic features 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 gold ore body: one was the quartz vein type controlled by crack propagation; another one was carbonaceous slate type controlled by bedding ductile shear zone and gliding nappe. The “fault valve- Seismic pump” metallogenic mechanism of deposit structure was also the important factor of gold deposit formation.
