| 摘 要： | 根据岩性、岩相、地震反射、测井响应、古生物、构造旋回、接触关系及同位素年龄测定等，将辽河盆地下第三系划分为４个层序和１２个亚层序。根据地层层序综合分析，辽河盆地早第三纪具有如下沉积演化特征：①构造运动的控制性；②沉积格架的不均衡性；③沉积演化的阶段性；④沉积中心的迁移性。

| Abstract: | Based on lithology, lithofacies, seismic reflection, log response, paleobiology, tectonic cycle, contact relationship and isotopic dating, the lower paleogene in the Liaohe Basin is divided into 4 sequences and 12 subsequences. On the basis of the synthetic analysis of stratigraphic sequence, the Earlier Paleogene in the Liaohe Basin is characterized by following sedimentary evolution: 1) controlling of tectonic movement; 2) disequilibrium of sedimentary framework; 3) stage of sedimentary evolution; 4) migrating of depocenter. |
