籍家岭砂岩露头为松辽盆地东南隆起区的泉头组粗粒曲流河河道砂体。通过对该砂岩露头精细描述和沉积构形分析，阐明了粗粒曲流河砂体的内部构成。其岩性相类型有块状或层状砂砾岩相；槽状交错层理含砾中、粗砂岩相；板状交错层理含砾中、粗砂岩相；平行层理砂岩相；低角度交错层理砂岩相及泥砾岩相等，这６种岩性相构成了侧向加积砂坝、顺流加积砂坝、河道边部浅滩、滞留沉积及小冲沟冲刷充填物等五种构成要素。砂体内部可识别出四个级别的界面，其中三级界面明显地反映出砂体为三次河道强化过程的产物，且后期河道强化过程明显冲刷、改造了前期河道的沉积物。从而形成了粗粒曲流河砂体内部复杂的沉积构形。
Jijialing sandstone outcrops are the Quandu group coarse-grained meandering river sand bodies in southeastern uplift area of Songliao basin. Through the fine description of the outcrop of the sandstone and the analysis of the sedimentary configuration, the internal structure of the coarse-grained meandering river sandbody is clarified. The lithological facies are massive or stratiform conglomerate facies; trough-interbedded strata containing gravelly and coarsely sandstone facies; plate-like interlayered strata containing gravelly and coarsely sandstone facies; parallel bedding sandstone facies; low-angle interlacing Stratigraphic sandstone facies and conglomerate are equal. The six lithologic facies constitute five types of structures: lateral sedimentation bar, downstream sediment barrage, bank edge bank, sediment deposition and small gully erosion filling Elements. Four levels of interface can be identified in the sand body, among which, the three-level interface clearly shows that the sand body is the product of the three-course river strengthening process, and the subsequent river strengthening process is obviously washed to transform the sediments of the previous river course. Thus, a complex sedimentary configuration inside the coarsely meandering meandering sand body is formed.
