摘　　要：东乡铜矿区主要断裂带SiO2明显为带入组分,K+、Na+、Ca2+、Mg2+属带出组分。Fe3+/Fe2+比值相对较低,成矿元素Cu、Pb、Zn、Ag、Au、As、Sb、Mo、Sn含量增高,属于明显的带入组分,可作为储矿断裂的找矿标志。The SiO2 of major fault zones is clearly taken in composition of K+?Na+?Ca+?Mg2+ in Dongxiang Copper deposit. The ratio of Fe3+/Fe2+ in major fault zone is lower than other faults. The content of metallogenic elements of Cu?Pb?Zn?Ag?As?Sb?Mo?Sn is increased and are obviously taken in. These appearances are prospecting characters of impounding fault.
