| 摘 要： | 巴丹吉林盆地是我国砂岩型铀矿产地之一。笔者通过沙枣泉地区地质调查、钻探查证和地球化学分析等,对该区铀成矿地质背景、矿床地质特征进行研究,重点探讨了沙枣泉铀矿床成因和成矿模式。依据沙枣泉地区的构造及盆地演化、铀矿化特征、控矿因素和成矿年龄等,认为区内铀成矿具有两阶段特征:即同生预富集矿化阶段和后生氧化改造富集成矿阶段;铀矿体主要赋存在早白垩世晚期的构造-沉积转化面,产于盆地形成后由于构造运动所产生的向斜凹陷部位。

| Abstract: | Badanjilin basin is an sandstone type uranium base in China. By geology survey, drilling explo- ration checking and geochemical analysis, the author studied the geology background, geology features of uranium mineralization, and focused the discussing on the forming genesis and model of uranium de- posit in Shazaoquan area. According to the structural coupling, basin evolution, uranium mineralization features, ore-controlling factors and minerlization ages, two phases of uranium mineralization were found in Shazaoquan area： syngenetie pre-enriched mineralization and epigenetic oxidization enriching minerali- zation. Uranium orebody is located above the intersurface of structural-sedimentary in early Cretaceous which is concentreated in the central depression of the basin formed by structural movement. |
