摘　　要：贵州锦屏花桥金矿已经有较长的民采历史。通过分析前人的研究成果,以及井下坑道编录和采样工作,得出含硅质有火山碎屑成分的浊积岩对金的富集有控制作用,浊积岩岩性变换的部位易出现含金石英脉等新认识。认为区域基底岩石金的地球化学丰度,矿体围岩岩性及构造地质作用是形成含金石英脉的三要素,并指出断裂破碎带及探索深部隐伏矿体为进一步找矿的方向。There is a long history of non-governmental exploitation in the Huaqiao gold deposit in Jinping County, southeastern Guizhou. Based on the results of previous studies, tunnel geologic records and sampling work, this paper considered some new understandings of the geological characteristics. The geochemical abundance of gold in this area, the characteristics of wall rocks and tectonic geological processes are the three elements required for the formation of quartz veins with gold. This paper also showed that the shear broken zone and exploitation at deeper levels are the further mining orientation.
