| 中文摘要: |
| 万古地区金矿床的成矿作用受到区域构造成矿的控制,矿区的断裂构造已经成为燕山中晚期金矿的定位构造.矿区北西西向断裂大部分是控矿、容矿构造,北东向断裂构造对矿脉的破坏作用有一定的影响,属成矿期后断裂构造.勘探线剖面图揭示了万古地区金矿床构造成矿具有金矿体侧伏特征、金矿体等距产出特征、金矿构造成矿作用多期性特征.冷家溪群是金的矿源层,万古金矿区的构造成矿作用是主要成矿作用,金矿化是剪切带长期活动的结果.从万古金矿、鲁源洞金矿、大洞金矿矿脉在走向和倾向的产出形态可以看出,富矿体都产出在构造张性扩容空间内.控矿层间破碎带中不同类型构造重叠部位是最有利的赋矿构造. |
| 英文摘要: |
| Gold deposits in the Wangu area are controlled regional tectono - metallogenic unit. Faults in the mining area are fixing position structures for gold deposits formed in middle to late Yanshanian. Most NWW - striking faults are ore - controlling and ore - hosting structures. NE - striking faults destroyed ore veins, and belong to post - mineralization structures. Lengjiaxi Group stratum is source bed for gold, and gold mineralization is result of long - term activities of a shear zone. Based on occurrences of ore veins in Wangu, Luyuandong and Dadong gold deposits, rich - gold ore bodies are all located in tension dilation fractures. Overlapping places of different type structures in the ore - controlling faults are the most available ore - hosting structures. |
