| 摘 要： | 通过对辽宁清原太古宙地体中代表性剖面的地层地球化学研究，表明本区太古宙上壳岩浑南群和清原群金含量明显低于地壳金丰度值，反映了金在后期成矿能量作用下，发生了迁移－聚集成矿的趋向，形成了各种类型金矿床。地层中金和其它微量元素相关性研究表明，金常与亲铁和亲铜元素形成多元素组合。

| Abstract: | A stratigraphic-geochemical study along typical geological sections in theArchean terrain of Qingyuan County indicates that the gold content of theArchean supercrust rocks of Hunnan Group and Qingyuall Group is much lowerthan the gold abundance of the crust.This suggests that,under the action oflate ore-forming energy,gold tended to migrate and accumulate,forming varioustypes of gold deposits. The correlations between gold and other minor elementsshow that gold often forms multi-element associations together with chalcophileand siderophile elements. |
