| 摘 要： | 位于新疆的萨瓦亚尔顿金矿床是我国西部的一个大型金矿床,矿区断裂和褶皱构造发育,总体构造线方向为NE-SW向,其断裂构造控制了矿区破碎蚀变带的展布,含矿岩层主要为上石炭统中段地层。为了揭示新疆萨瓦亚尔顿金矿床容矿岩系的沉积环境,文章对容矿岩石稀土元素和微量元素的地球化学特征进行了分析。研究表明,萨瓦亚尔顿金矿床容矿岩系的稀土配分,负Eu异常现象较明显,这与此类岩石的富含钙质杂基和异常高的K2O含量有关;根据容矿岩系稀土元素及微量元素地球化学特征,结合地层结构特点和化石特征,可判别其容矿岩系沉积时的构造环境应属大陆岛弧,其容矿岩系形成于半深海-浊流沉积,弱还原环境。

| Abstract: | The Sawaya'erdun gold deposit located in Xinjiang is of a large-size mine in western China.In this mine area,there are well-developed faults and folds with a general structural trend in NE-SW direction.The distribution of broken alteration zones is controlled by the faults.The ore-bearing rocks are mainly in the middle member of upper Carboniferous.In order to reveal the sedimentary environment of host rocks of the Sawaya'erdun gold deposit,Xinjiang,this paper analyzes the REE and trace element geochemical ... |
