| 摘 要： | 砂金是黄金的重要来源之一,一般认为砂金矿的形成和富集主要与三四级水系密切,而不重视一二级水系,认为不易形成砂金矿.近2年来,经地质调查和研究发现在长江上游一级水系中富集有砂金矿。砂金主要赋存于第四系冲积层内,砂砾层中普遍含金,品位较高,埋藏浅,有利于开采;成矿条件较好,具有一定远景储量。

| Abstract: | It is said that placer gold is mainly formed and concentrated in three-four class water systemly,but not pay attention to one-two class water system.Recent two years,investigations have discovered that placer gold conceatrated in one class water system of Changjiang headwater.These placer gold mainly concentrated with in alluvial deposit of the Quaternary system of sandpebble bed,content of gold universal,rich ore of grade,shallow of bury,condition mine of favourable,considerable of prosper. |
