| 中文摘要: |
| 上成金矿位于张八岭构造带北部，是受断裂构造控制的岩浆热液型金矿。通过研究厘定出一条近SN向断裂破碎带—其为管店-龙王尖断裂的北段分支管店-下马断裂—以及F1、F2、F3三条近NW向顺层滑动断裂。石英脉型金矿化受近NW向的顺层滑动断裂构造控制，矿体空间展布上具有平行似等距特征，蚀变岩型金矿化受近SN向断裂破碎带控制。上成金矿床2种不同金矿化类型是同一成矿作用在不同性质的控矿断裂构造下的具体表现，空间结构具有上部石英脉型金矿化下部蚀变岩型金矿化的关系。断裂构造产状变化部位有利于形成矿化弱的厚矿体，反映断裂构造局部地段的高引张空间有利于形成第Ⅰ阶段厚石英脉；而矿脉的分支复合、膨大缩小部位有利于矿化富集，反映断裂构造多期活动强烈地段则有利于Ⅱ、Ⅲ阶段矿化叠加富集。矿化的局部富集与矿体的厚度具有一定的负相关性。结合矿化特征、构造控矿规律总结分析，对上成金矿床深部和外围进行了成矿预测。 |

| Shangcheng gold deposit is located in the north of Zhangbaling tectonic belt, it was magmatic hydrothermal type gold deposit Controlled by fractures. A nearly SN broken fracture belt was set out—Guandian-Xiama fracture, which was the northern branch section of Guandian-Longwangjian fault, and F1, F2, F3 three close to NW bedding sliding fractures were also set out. Quartz vein type gold mineralization were controlled by close to NW bedding sliding fractures, spatial distribution of the ore body were with parallel equidistant like features. alteration rock type gold mineralization was controlled by nearly SN structural fracture zone. The two different gold mineralization were a concrete performance of the same mineralization in the different nature of the ore-controlling fault. Space structure had a lower altered rock type gold mineralization, the upper quartz vein type gold mineralization characteristic. Fault occurrence change was good for forming thick and weak mineralized ore body, reflecting that the high extensional local district of faults favored the first stage thick quartz vein; Also the place of vein’s branch or compound and expanding and thinning out wre good for mineralization enrichment, reflecting that the district of highly strong multiphase activity faults was in favor of Ⅱ, Ⅲ stage superimposed mineralization enrichment. In this article, author also combined mineralization, structural control laws summary analysis to do the metallogenic prediction on the periphery and deep of the Shangcheng gold deposit. |
