DYNAMIC CHARACTERISTICS OF RILLING AND EVOLUTION OF HUANGXIAN EOGENE FAULT BASIN,SHANDONG

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.
