采用岩石学与粒度分布特征相对比的方法，系统研究了松辽盆地３个典型剖面和１０余口探井的白垩系碎屑岩层序。结果表明，陆相碎屑沉积的岩石组合及其岩性、岩相特征与相应的薄片粒度分布结果（直方图、概率累积曲线、偏度（ＳＫ１）和标准偏差（δ１）等）具有良好对应关系。据此可明显识别出松辽盆地白垩系（泉头组－嫩江组）的５种主要沉积相，即冲积扇相、冲泛平原相、三角洲相、滨浅湖相和（湖泊）水下重力流相。文中分别论述了上述５种沉积相的岩石组合特征与粒度分布特征，探讨了二者内在联系。本文提出的陆相沉积环境定量判别标志，在其它陆相盆地沉积环境研究中具有借鉴意义。
Based on the contrast between petrology and particle size distribution, the sequence of Cretaceous clastic rocks in three typical sections and more than 10 exploration wells in the Songliao Basin was systematically studied. The results show that the rock assemblages and their lithology and lithofacies characteristics of terrestrial clastic sediments are in good agreement with the corresponding results of the slice size distribution (histogram, probability cumulative curve, skewness (SK1) and standard deviation (δ1), etc.) relationship. Based on this, five major sedimentary facies of the Cretaceous (Quantou Formation - Nenjiang Formation) in the Songliao Basin can clearly be identified: alluvial fan facies, rhyolite facies, delta facies, shore-shallow lacustrine facies, and (lake) Flow phase. In this paper, the characteristics of the rock assemblages and the characteristics of the grain size distribution of the five sedimentary facies mentioned above are discussed respectively, and the intrinsic relations between the two are discussed. The quantitative identification mark of continental depositional environment proposed in this paper is of great significance in the study of sedimentary environment in other continental basins.
