摘　　要：通过成矿条件分析认为,海拉尔盆地具有较为丰富的铀源,其沉积层厚度大,富含有机质,有利沉积相带发育,具有渗入型自流水盆地特征,补给-径流-排泄配套机制完善,水动力条件较好.在对海拉尔盆地地质条件分析基础上,结合航空放射性资料铀异常特征的解释,预测了5个值得进一步工作的铀成矿远景地区.Analysis on the metallogenic conditions of Hailaer basin shows rich uranium sources in a great thickness of sedimentary layer with abundant organic matter and developed beneficial sedimentary facies belts.The Hailaer basin is of infiltrating artesian type,with perfect recharge-runoff-drainage mechanism and good hydrodynamic condition.On the basis of geologic analysis for Hailaer basin,combined with the uranium anomalous characters interpreted from airborne radioactivity survey data,five uranium mineralization prospects that deserve further work are predicted.
