| 摘 要： | 中国北东部中新生代盆地是地浸砂岩型铀矿的主要勘查区.自1996年开始,为了寻找地浸砂岩型铀矿床,对这些盆地开展了1:500 000-1:200 000铀矿区域地质调查,投入了大量钻探工作量.运用可地浸砂岩型铀矿评价准则,对松辽盆地、海拉尔盆地的成矿地质条件进行分析,提出成矿的有利层位和远景区、段,为该区寻找地浸砂岩型铀矿床提供了科学依据.

| Abstract: | The Meso-Cenozoic basins in Northeast China are major exploration region for in-situ leachable sancl-ston-type uranium deposits. Since 1996, large amounts of borehole drilling have been performed in the basins during the regional reconnaissance (1: 500 000 - 1: 200 000) for prospecting in-situ leachable sandstone-type uranium deposits. The theory and method of regional prognosis criteria for the sandstone-type uranium deposits are adopted to study the metallogenic conditions of Songliao and Hailar basins. The favourable horizons and potential areas are proposed, which provide a foundation for locating the in-situ leachable sandstone-type uranium deposits. |
