摘　　要：运用层序地层学原理和方法 ,在黄县盆地进行高频层序地层划分的基础上 ,对黄县早第三纪断陷盆地充填演化的动力学特征进行研究。通过动力学模拟及充填演化分析 ,认为黄县盆地的充填演化过程受两期裂陷作用的控制。第 I裂陷期以盆地有间歇的快速沉降为特征 ;第 II裂陷期表现为盆地的持续缓慢沉降。By means of the principle,method and technology of sequence stratigraphy,The dynamic characteristics of filling and evolution of Huangxian Eogene fault basin are studied,based on the classification of high frequency sequences.The results of dynamic simulation as well as filling and evolution analysis show that the filling and evolution processes of Huangxian fault basin were controlled by two rifting stages.The first stage is characterized by intermittently fast subsidence, and the second stage presents continuously slow subsidence.These two stages controlled the formation and development of sequences.
