| 摘 要： | 通过对南祁连岛弧带红灯沟矿床的形成背景、构造演化,以及金矿化研究分析认为,红灯沟矿区位于汇聚板块边缘最重要的金矿成矿带上,矿床赋存于一右行走滑韧性剪切带中。矿体主要发生在韧性剪切带中,构造变形越强,矿化越好。成矿物质为深部来源,可能与隐伏酸性岩体的成矿作用有关。后期的张性填充石英脉是重要的成矿构造。根据矿床的成因,建立了矿区成矿模式图,指出了有利的找矿部位。

| Abstract: | This paper mainly analyses the background and structural evolution of the Hongdenggou gold deposit,which lies in the island arc area of Southern Qilian Mountain, and makes clear the relationship between ductile shear zones and gold deposits. The Hongdenggou gold deposit locates in the plate convergent margin, which is the most important gold mineralisation zone. Based on the investigation, we find out the character of shear zones,and rope out the area of mineralization abnormity. We also found gold minerali... |
