| 摘 要： | 川北陆相砂岩型铀矿主岩中有机质是铀的主要富集剂。铀在其中存在形式有:1.矿物铀;2.吸附铀;3.腐植酸合铀酰络合物。含铀有机质相当煤化程度较低的褐煤,铀矿化主要富集在结构镜质体之中。有机质对铀的富集作用表现在成煤作用的各个阶段。

| Abstract: | Organic matter is a main concentrating agent for uranium in the continental sandstonetype uranium deposit in North Sichuan, in which the forms of existence of uranium include: 1. uranium mineral; 2. uranium in absorptive state: 3. uranyl complexes with humic acid. Uanium-bearing organic matter is equivelent to lignite with relatively low degree of coalification and uranium mineralization is mainly concentrated in the telinite. Uranium concentration by organic matter is displayed in each stage of coalification. |
