| 摘 要： | 通过分析铀迁移、沉淀、富集的成矿特点,结合伊犁盆地南缘铀矿床中铀矿石成分研究,分析了砂岩型铀矿成矿机理.指出在层间氧化带砂岩型铀矿床中,铀主要以碳酸铀酰络合物形式迁移,在富含有机质、硫化物、硫化氢等有效还原剂的条件下,形成强烈的地化反差还原地球化学障环境,铀还原沉淀,最后富集成矿.为指导普查找矿、开展铀矿床矿石成分研究提供参考依据.

| Abstract: | The paper describes the ore characteristics of uranium migration, precipitation and concentration. Uranium migration mainly occurs as uranyl carbonate in the groundwater. The precipitation and concentration of uranium under these conditions occur with concentrated organic matter and in ageochemically reducted environment. A summary of the characteristics of sandstone-type uranium mineralization and of uranium deposit research is a good basis for future exploration for uranium deposits. |

| Keywords: | migration of uranium sedimentary accumulation of uranium metallogenesis of uranium |
