松辽盆地第三系可地浸砂岩型铀矿成矿地质条件前人曾从区域上作过分析，从1998年起，该区投入了大量钻探工作，进行1∶20万可地浸砂岩型铀矿区调。本文在钻孔编录及剖面编制、样品分析的基础上，从岩性、岩相，岩石化学、有机质、铀含量、岩石孔隙度、砂体分布、层间氧化带发育程度及水动力条件等方面，进一步分析了该区第三系铀成矿条件。

Regional analysis on metallogenic conditions of in-situ leachable sandstone-type uranium deposits in Tertiary of Songliao basin was made by previous researchers. Since 1998, a great amount of borehole drilling has been performed in the basin in order to do regional reconnaissance (1∶200 000) on in-situ leachable sandstone-type uranium deposits. On the basis of borehole documentation, profile compilation and sample analysis, this paper further analyses the uranium metallogenic prerequisites in Tertiary of the southern part of Songliao basin in aspects of lithology and lithofacies, petrochemistry, organic material, uranium content, porosity of rocks, distribution of sandstone bodies, as well as the development of interlayer oxidation zone and hydrodynamic conditions.
