| 中文摘要: |
| 上宫金矿位于华北地台熊耳山隆起部位,大型断裂带龙脖—花山背斜的南翼。矿区出露地层主要为中元古界熊耳群许山组火山岩系,这套火山岩化学成分表现为富铁、多钾、低钙铝的特点。矿区内断裂发育,以北东向为主,近南北向和近东西向次之。文章通过对上宫金矿成矿地质特征的分析,结合前人的研究成果,归纳出上宫金矿床地层、构造、岩浆岩三位一体的控矿机制,提出了地层、构造—岩浆岩以及围岩蚀变3个典型的找矿标志。 |
| 英文摘要: |
| The Shanggong gold deposit is located in Xiong’ershan uplift of North China Craton and the southern wing of Longbo-Huashan anticline within the large-sized fault zone. The exposed strata are mainly Meso-proterozoic Xiong’er formation volcanic rock series of Xushan Group, which are characterized with iron-rich, high potassium and low calcium aluminum in chemical compositions. The fractures are well developed in the deposit area, the fault strike mainly is Northeast-trending, secondary nearly north-south and east-west trending. Based on the analysis of gold mineralization characteristics, in combination with the result of previous studies, this paper summarized the ore-controlling mechanisms of Trinity, i.e., strata, structure, and magmatic rocks, and proposed three typical prospecting indicators of strata, structure-magmatic rock and wall rock alteration. |
