摘要
上奥陶统铁石达斯群夕卡岩化硅质岩是东昆仑肯德可克钴金矿床的主要围岩之一,具有沉积结构构造。岩石的Fe2O3、Co、Au、Bi含量高;Fe-Mn-(Co+N i+Cu)×10三角图解中,样品投影于热水沉积区。岩石的稀土元素组成表明含金硅质岩由热水沉积作用形成。
Skarnization siliceous rocks in the lower Ordovician Tieshidasi group is one of the dominant host rocks of Kendekeke cobalt - gold deposit. The rocks have sedimentary structure. Content of Fe2O3 , Co, Au and Bi is higher comparing with non hydrothennal sedimentary siliceous rocks. Fe - Mn - （ Co ＋ Ni ＋ Cu） × 10 triangle diagram shows hydrothermal sedimentary feature. REE composition of siliceous rocks demonstrates hydrothermal sedimen- tary origin.
