  • Based on the analysis of sequence type and developing models of the lower Tertiary of Raoyang depression, the controlling factors of every types of sequence are analyzed according to its configuration. It is considered that at the circumstance that the supply rate of sediments is stable, the configuration of rift sequence ,the initial and closing time of the developing of its system tracts are determined by the subsidence rate and the time of highest rate of subsidence of the basin basement. The style of parasequence set are controlled by the ratio of sediment supply to the accommodation, local highest rate of sediment supply can produce progradational parasequence set. The change of climate is also a controlling factor of the development of sequence. In aridity period, lake level change and the configuration of sequence are controlled by climate. 

Abstract: Based on the analysis of sequence type and developing models of the lower Tertiary of Raoyang depression, the controlling factors of every types of sequence are analyzed according to its configuration. It is considered that at the circumstance that the supply rate of sediments is stable, the configuration of rift sequence ,the initial and closing time of the developing of its system tracts are determined by the subsidence rate and the time of highest rate of subsidence of the basin basement. The style of parasequence set are controlled by the ratio of sediment supply to the accommodation, local highest rate of sediment supply can produce progradational parasequence set. The change of climate is also a controlling factor of the development of sequence. In aridity period, lake level change and the configuration of sequence are controlled by climate. 
