摘　　要：运用地质、地震及基底磁性体分析相结合方法 ,预测了松辽盆地北部基底石炭—二叠系的分布 ,结果表明 :石炭—二叠系在全区不很均匀 ,在盆地北部的中央隆起带以东地区和西北地区较厚 ,其它地区相对较薄或不发育 ,一般厚度为 3.0～ 4 .5km ,最厚的三肇地区达 6 .0km .石炭—二叠系总体可分为 2个带 。The paper predicts the distribution of Carboniferous\|Permian system on the base of Songliao Basin by using the synthetic methods of geological, cosmic and basal magretic body analysis. The results indicate that Carboniferous\|Permian system is uneven in the whole area. And it can be divided into two zones:low\|grade metamorphite zone in the east and low\|grade metamorphite zone in the north\|west. The area in the east of the central high part of the basin and in the north\|west is thicker than the other parts of the basin,which are relatively thin and underdeveloped. The average thickness is 3 000～4 500 m, and the thickest place can reach 6 000 m in Zhaodong, Zhaoyuan and Zhaozhou.
