     Based on the geological, seismic, well logging and other data in West Slope of Songliao Basin, and mo- reover through the field geologic, radioactive geophysical, hydrogeological investigations/surveys and so on, the analyses are shown as follows with the help of the mineralizing theory of sandstone-type uranium deposit ： the miner- alizing conditions of this kind of uranium are greatly good, the phreatic oxidation in West Overlap Belt is well de- veloped, and moreover there is a latent surface uranium anomaly. The hydrodynamic system and faulting in the middle of the western slope possess much obvious controlling action to the uranium aggregation, thus make the re- gion develop into the favorable area of the sandstone-type uranium deposit in the ancient stream channels, the main mineralized horizon is Sifangtai Formation and there are two kinds of uranium accumulating mode with different peri- ods. In West Slope of Songliao Basin, the key uranium deposit survey areas are focused on the paleo-channels, theintersections between the rivers and tributaries and furthermore the deltas into the lake for several major river systems.
