随着孙吴—嘉荫盆地勘探程度的提高,以及松辽盆地内部盆地级沉积大剖面的不断完善,对于孙吴—嘉荫盆地及松辽盆地二者之间的关系进一步明晰。从盆地的地层序列上看,松辽盆地嫩江组与孙吴—嘉荫盆地太平林场组的时代与岩石地层特征一致;从盆地形成与演化过程来看,其发育阶段与演化特征相似;从两个盆地地理位置与二者二级构造单元分布格局来看,具有相互连续的特征,只是被后期小兴安岭的火山岩出露所破坏;从沉积层序特征来看,松辽盆地北部未见边缘沉积相,故其现今盆地边界必不是原型盆地的边界。
With the improvement of exploration degree in Sunwu-Jiayin basin and continuous improvement of the basin-wide sedimentary profile in the Songliao Basin, the relationship between the two areas will be further clarified. From the sequence of the stratigraphic sequence of the basin, the epoch and lithostratigraphic features of the Nenjiang Formation in the Songliao Basin and the Taipinglinchang Formation in the Sunwu-Jiayin Basin are consistent. The developmental stages and evolution characteristics of the basin are similar in terms of the formation and evolution of the basin. In terms of sedimentary sequence characteristics, there are no marginal sedimentary facies in the northern part of Songliao Basin Therefore, the boundary of today’s basin must not be the boundary of the prototype basin.
