| 摘 要： | 通过对洞子沟银多金属矿稀土元素测试分析，认为赋存于常州沟组的洞子沟银多金属矿的矿源层应为沉积岩，并推断本区与上部大红峪组富碱火山岩无成因上的因果关系。岩石、矿石稀土球粒陨石标准化分布模式，均呈倾斜度相似的平滑曲线，负铕异常均无或微弱，都较好地反映了物源-矿源层-矿石稀土元素的继承发展的相关特征。同时对该矿床成矿模式作了进一步探讨。

| Abstract: | It is considered that the source layer for the Dongzigou silver polymetallic deposit in Changzhougou group may be sedimentary rock and it seems that there is no genetic relationship with the above alkali rich volcanic rocks of Dahongyu group based on the analyzing of REE elements in the deposit. Chondrite normalized REE patterns of rocks and ore all show a smooth curve with a similar gradient and no or weak negative europium anomaly ,which ideally illustrate the associated characteristics of the REE evolvement from matter source to ore source layers and ores. The ore-forming model for the deposit is further discussed. |
