文章以方山口 U V型非常规铀资源为研究对象,对该区矿化层和赋矿围岩进行了元素地球化学分析,结果表明：U、V呈明显正相关；在铀多金属矿化层中,与超基性岩浆有关的 Cr、Co、Ni元素超常富集；稀土元素配分模式中呈现弱 Ce 负异常,Eu 正异常；矿化层与围岩分析数据在ω(La)/ω(Yb)－∑REE图中投影点落在玄武岩区内。研究认为,方山口铀钒型非常规铀资源形成于早寒武世裂谷环境,在同沉积海相黑色岩系形成的同时,伴随着海底喷流作用,U、V多金属矿化层的形成可能与受超基性岩浆作用影响的热水作用相关联。

This paper deal with Fangshankou U V type unconventional uranium resource.Element geo-chemical analysis of the mineralized and host rock brought the fellowing facts:(1 )U and V is signifi-cantly positive correlated;(2)Cr,Co,Ni are abnormally enriched in rocks related to ultrabasic magma in uranium polymetallic mineralization layer;(3)Weak negative Ce anomaly and of positive Eu anomaly occurred in REE patterns;(4)ω(La)/ω(Yb) ∑REE diagram of mineralization layer and host rock fall into the basalt area.This paper suggested that both of the polymetallic mineralization layer and host rock are formed in the early Cambrian Beishan rift valley environment.With the formation of the synsedi-mentary of marine black rock series and the process of submarine backwash,the forming of the U V polymetallic mineralization is influenced via the hydrothermalism related with ultrabasic magmatism.
