| 摘 要： | 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。

| Abstract: | 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 arcshaped 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. |
