摘　　要：针对松辽盆地周边二叠系地表出露分散且多呈断片产出的复杂特点 ,运用生物化石、岩性特征、地层接触关系综合分析方法 ,建立了地层间的相互层位和对比关系 .二叠系分布较广 ,岩相基本稳定 ,厚度变化较大 .区内二叠系下统为偏碱性中酸性火山岩 ,其上是海相或海陆交互相碎屑—碳酸盐岩建造 ;上统为陆相碎屑岩建造 .In the Carboniferous in Songliao basin peripheral earth's surface, outcrop scatters about and broken rocks are more complicated. The mutual stratigraphic horizon and correlation is established by comprehensive analysis of the living creature fossil, rock characteristic and stratigraphic contact relation. The Permian in Songliao basin periphery scatters widely and facies are more stable, but the thickness changes obviously. Lower Permian is alkalic neutral-acid volcano rock, its top is fragments-carbonate rock construction of sea and land mutual facies. Upper Permian is land facies fragments rock construction.
