| 摘 要： | 本文研究了西秦岭铀矿床含矿热液物理化学条件的改变对铀沉淀富集的影响。研究表明，铀在相对还原条件下迁移，而在相对氧化条件下沉淀富集。铀的沉淀富集主要发生在含矿热液的温度、压力和氧逸度大幅度降低，酸性增强及氧化－还原电位增高的物理化学条件下。

| Abstract: | The reduction and enrichment of uranium effected by the changes of physico-chemical conditions of U-bearing hydrothermal solution in the west Qinling uranium deposits was studied by. It is indicated that uranium was moved out in the relative reducing condition and enriched precipitation in the relative oxidizing condition. Uranium mineralizing process occurred in the stage of that high temperature and pressure, high fo2 and pH, and low Eh was changed into low temperature and pressure, low fo2 and pH, and high Eh. |
