阳山金矿床位于甘肃省文县境内，矿区内共发现矿床（点）210余处。矿体沿观音坝安昌河断裂带分布，位于文县弧形构造带内，矿床受该断裂带严格控制，呈雁行排列。通过对阳山金矿区及矿床地质特征的研究，认为矿床成因属于浅成低温热液蚀变岩型，中低温，偏碱性，属浅成成矿环境。归纳总结了其找矿标志，对阳山矿区寻找同类型矿床具有指示意义，同时也可为其它同类型矿床提供参考。
Yangshan Gold Deposit is located in Wenxian ,Gansu province ,where more than 210 deposits were dis-covered.The mineral body spreads along the Guanyin dam -Anchang river fracture belt ,and is located in the arc-shaped tectonic structure .The deposit is strictly controlled by the fracture ,aligned with form of proceeding wild geese . Based on the study of Yangshan Gold Deposit and its geological features ,the paper takes that the genesis of the deposit is hypabyssal epithermal fluids altered rocks type .The ore-forming environment is medium low temperature , alkaline and hypabyssal .Prospecting indicators are summarized ,providing guidance for exploring similar deposits in Yangshan mining area and being referential for other similar deposits .
