摘　　要： 同位素由于其独特的化学特性,在地质研究中广泛运用来测定地质体年龄和追踪成矿物质来源。许多学者对相山铀矿田进行了同位素地球化学的研究,具体成果表现在对地质体形成时代、示踪成矿物质来源以及热液来源的认识方面。对相山火山-侵入岩体的成岩年龄研究的最新成果表明其应归属于白垩世,而不是之前认为的侏罗世;还有学者认为相山铀矿成矿为一期成矿,成矿时间应在145~85 Ma之间。成矿物质来自火山岩体,同时也有幔源物质的参与;作为成矿围岩的火山侵入杂岩来源自深部地壳熔融;成矿热液有大气降水的参与。 Isotopes are widely used in geological studies due to their unique chemical properties to determine the age of the geologic body and to trace the source of ore-forming materials. The isotope geochemistry ofXiangshan uranium ore field was studied by many researchers. Specific results are expressed in the era of geological formation, tracing of mineral origin and hydrothermal sources. The latest results of the study on the diagenetic age of Xiangshan volcanic-intrusive rocks show that they should be formed in the Cretaceous, not previously thought of the Jurassic, Some researchers believe that Xiangshan uranium mineralization for a metallogenic, Mineralization time should be between 145-85 Ma. Mineralization not only came from volcanic rocks, but also the participation of mantle-derived substances. Volcanic intrusive complexes, which are ore-forming rocks, are derived from deep crustal melting. Metallogenic hydrothermal fluids are involved in precipitation.
