摘要
松辽东缘新立城盆地沙河子组（Ｊ３ｓｈ）的盆地充填特征展示了一个水进－水退过程，在这一过程的不同阶段形成了不同的沉积层序，包括湖盆层序和冲积层序（流域盆地层序）。湖盆层序属于新立城断陷盆地的发育早期，冲积层序属于新立城盆地的发育晚期。这两种不同类型的层序发育正是松辽盆地断陷阶段盆地动力学机制的沉积、地层响应。
The basin fillings of Shahezi Formation(J 3sh)in Xinlicheng basin of the east margin of the Songliao demonstrates a transgressive regressive process during which the different sequences including lake basin sequence and alluvial sequence(river basin sequence)developed at different stages.The lake basin sequence occurred in lake basin belonging to early stage of Xinlicheng basin's development and the alluvial sequence occurred in river basin belonging to later stage of that.The developments of those two types of sequences are the sedimentary and stratal response to the basin dynamics of the Songliao basin at rifting time.
