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。
暘山金礦床位于甘肅省文縣境內,礦區內共髮現礦床(點)210餘處。礦體沿觀音壩安昌河斷裂帶分佈,位于文縣弧形構造帶內,礦床受該斷裂帶嚴格控製,呈雁行排列。通過對暘山金礦區及礦床地質特徵的研究,認為礦床成因屬于淺成低溫熱液蝕變巖型,中低溫,偏堿性,屬淺成成礦環境。歸納總結瞭其找礦標誌,對暘山礦區尋找同類型礦床具有指示意義,同時也可為其它同類型礦床提供參攷。

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 .
