| 摘 要： | 天水花石山金矿床是甘肃东南部地区具代表性的石英脉型金矿床之一。本文通过该地区地质找矿成果,综合分析了矿床成矿地质条件、地质构造特征、控矿因素等,认为金矿体主要分布于NW向构造带中。矿区近EW向、NW向区域深大断裂旁侧的次级NW向断裂是主要的容矿构造,也是控制矿体的分布及规模。在此基础上探讨了金矿床成因类型,提出了该类金矿床地质找矿标志。

| Abstract: | Huashishan gold deposit in Tianshui is one of the representative quartz vein type gold deposits in southeast Gansu.By analyzing the metallogenic condition,the geotectonic features and the ore-controlling factors of the deposit,the prospecting findings in this region suggest that gold ore bodies are mainly distribu-ted in NW-trending structural belts.NW-trending secondary fault which is beside near EW-trending and N-W trending regional discordogenic fault is the main host structure,and it controls the distribution and scale of the ore body.On this basis,the paper has explored the genetic types of the gold deposits,and put forward the clues for prospecting of this type of gold deposits. |
