摘要
通过总结阳山金矿安坝矿段南部矿脉群地质特征,分析了控矿地质条件,得出矿区成矿是地层、构造和热液三种因素相互作用的结果,矿化富集层位主要为中泥盆统三河口组第三岩性段,近东西向安昌河-观音坝断裂是成矿最主要的控制因素,泥盆系三河口组和碧口群提供成矿物质,进而归纳出找矿标志,为在西秦岭南亚带寻找类似矿床提供参考。
This paper deals with geological and geochemical features, ore control factors and ore guides of the south of the Anba ore block of the Yangshan Au deposit in Gansu. The study indicates that the Au mineralization is confined to the 3rd Member of the Middle Devonian Sanhekou Formation and controlled by stratigraphy and nearly horizontal Anchanghe-Guanyinba fault. Ore material was derived from the Devonian Sanhekou Formation and the Proterozoic Bikou Group.
