Abstract: 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.
