| 摘 要： | 金龙山金矿床产于秦岭元古宙－晚古生代海槽特殊有限洋盆之中，矿床赋存于上泥盆统南羊山组和下石炭统袁家沟组，该层位金丰度度，认为赋矿层位为矿源层。通过对矿源层沉积区域地质环境，地层岩石组合，岩相结合，沉积地球化学诸特征分析，以揭示矿源层是在动荡海盆环境下喷流沉积作用的结果，构造，火山热液活动是金矿源层形成根本原因

| Abstract: | Jinlongshan gold deposit develops in the special limited ocean basin of Proterozoic-Upper Palaeozoic ocean trough in Qinling. The deposit occurs in Nanyangshan Formation of Upper Devonian and Yuanjiagou Formation of Lower Carboniferous, this position contains high gold abundance. The orehosting position is considered the source bed. According to depositional regional geological setting, rock association, lithofacies assemblage and depositional geochemistry, the source bed is considered the produce resulted by the deposition of volcanic projection in a turbulent ocean basin envirnment. Structural and volcanic hydrothermal activities are basic reasons for the formation of source bed. |
