新疆511砂岩型铀矿床稳定同位素地球化学特征
Geochemical Feature of Stable Isotopes in Sandstone-type Uranium Deposit 511 in Xinjiang, China
摘要
Abstract
Uranium deposit 511 is a typical in-situ leachable sandstone-type uranium deposit, study on its geochemical characteristics of stable isotopes may give help to the exploration and mining design of orther deposit of the same kind. Considering the geology feature of uranium deposit 511, we analyzed its geochemical features of stable isotopeic S, C, H and O by using EA-MS, MAT-253, GASr Bench and GASBENCH-MAT253 facilities. The experimental results indicated that S has close relationship with the process of sulfate changing into sulphide through reducing bacteria, C may come from organic carbon, the relative low and negative value of C, H and O isotopes suggest that the metallogenic fluid were originated from atmospheric precipitaion.关键词
