| 摘 要： | 石湖金矿101、116矿脉深部延伸稳定,品位有所提高,产状变化不大,南于深部探矿进展较好,而使其成为太行山中段大型金矿.石湖金矿的矿脉明显受断裂构造控制,总体属岩浆期后热液石英脉-断裂构造蚀变岩型矿床.本文采用幔枝构造新视角开展研究,通过对地质背景研究及铅、硫、硅、碳、氢、氧同位素的分析表明:石湖金矿成矿物质主要来源于地球深部,成矿溶液主要为岩浆水,混有部分大气水.进而探讨了其成矿作用,建立了成矿模式,提出了具体找矿建议.

| Abstract: | With the stable extension of No. 101 and No. 116 ore veins revealed by the prospecting work at depth, the grade of Au has been steadily increased and the Shihu gold deposit has gradually become a large-size gold deposit in the middle of Taihang Mountains. In general, the deposit belongs to a post -magmatic hydrothermal deposit of quartz vein-fault altered rock type, with its ore veins strictly controlled by the fault structure. On the basis of studying the geological setting and analyzing ore-forming lead, sulfur, silicon, carbon, hydrogen and oxygen isotopes and from the new angle of view of the mantle branch structure ore -forming theory, the authors revealed that the ore-forming materials mainly came from the deep part of the earth and the metallogenic solutions were derived mainly from the magmatic water and partly from the atmosphere water. This paper has also discussed the ore-forming process of the Shihu gold deposit, established a metallogenic model for this area, and put forward some suggestions for further prospecting. |
