Data for: Organic geochemistry and gas prospectivity of Permian source rocks in the western margin of the Songliao Basin, northeastern China

The Permian in western margin of Songliao Basin is a strategic potential field of oil and gas resources in northeastern China, but the systematic researches since few boreholes were drilled up to Permian strata, as well as there is a lack of seismic and well-logging data. This paper presents the lithological composition of the Permian Formations on the basis of regional geological survey in western margin of Songliao Basin.西辽河盆地西部边缘的Permian层段是中国东北部油气资源战略潜力的重要区域，然而，自钻探至Permian层段以来，系统性的研究工作尚显不足，且地震和测井数据的缺乏亦为明显短板。本文基于对西辽河盆地西部边缘的区域地质调查，阐述了Permian地层岩石组合情况。
