| 摘 要： | 中亚地区发现大量可地浸砂岩型铀矿床引起了我国的重视 ,目前正在积极开展此类型铀矿的找矿工作。我国北西部是寻找类似中亚地区层间氧化带后生地浸砂岩型铀矿床最理想的地区 ,本文在论述了区域大地构造特征、地壳演化与区域铀成矿带形成的基础上 ,着重阐明了区域中新生代盆地地浸砂岩型铀矿床形成的铀源条件、盆地类型与结构及富铀性对形成地浸砂岩型铀矿的影响 ;并以区内已有层间氧化带地浸砂岩型铀矿床为例 (伊犁盆地、二连盆地与测老庙盆地砂岩型铀矿床 ) ,论述了盆地砂岩型铀矿床形成的岩相古地理条件、水文地质与层间氧化带发育条件及对铀成矿的影响 ;并阐述了本区层间氧化带地浸砂岩型铀矿床的分布规律

| Abstract: | On the basis of geologic conditions of the northwestern part of china and basic regional geotectonic features, and crustal evolution and formation of regional uranium minerogenetic belts, this paper emphasises on expounding uranium source conditions of forming in situ leaching sandstone-type uranium deposits, the formation and distribution of uranium-bearing strata in the Meso-Cenozoic Era basins in this region, and the influence of basin types, structure and uranium enrichment on the formation in situ leaching sandstone-type uranium deposis. |
