摘　　要：该文对510-1铀矿床矿石及地层中的各类岩石的微量元素地球化学特征进行了研究,结果表明,该矿床是一个以铀为主,伴生有Mo、V、Co、Ni、Zn等多种成矿有用元素的多金属矿床。各种成矿金属元素在各类岩石中的分布特征各不相同,U与伴生有用成矿元素的相关性研究表明,Mo、V、Co、Ni、Zn在铀矿石中虽有明显富集和矿化,但与U无明显相关关系;该矿床的成矿物质来源与硅质岩、硅灰岩和岩浆岩关系较为密切,U在沉积过程中形成了初始富集,后期的岩浆叠加改造作用对多种元素的进一步富集起到了重要影响,富集多种微量元素的中酸性岩浆岩是多种成矿物质的重要来源。In this paper,the trace element geochemistry of ore mineral and various rocks from the strata of510- 1 uranium deposit in Zoige were studied,the results show that the deposit is a polymetallic deposit which is uranium- based and associated with useful ore- forming elements,such as Mo,V,Co,Ni,Zn,etc. The distribution characteristics of various ore- forming metal elements in various rocks are different,the study of correlation between U and associated useful ore- forming elements showed that although Mo,V,Co,Ni,Zn in uranium ore are significantly enrichment and mineralization,but have no obvious correlation with U; The source of mineral is closely related with siliceous,siliceous limestone and magmatic rocks,Initial enrichment of U formed during deposition,and the magmatic superimposition and reformation played an important influence on further enrichment of various of ore- forming elements,intermediate acid magmatic rocks that enriched a variety of trace elements are important sources of many ore- forming materials.
