| 摘 要： | 在分析饶阳凹陷古近系层序类型和发育模式的基础上，根据层序的结构特点，对每种层序发育的控制因素进行了分析。认为在沉积物供应速率变化不大的情况下，盆地基底的的沉降速率和沉降高峰期的时间决定着裂谷期层序的结构、各体系域开始发育和结束的时期。沉积物供应速率和可容空间变化的速率的比值决定着准层序组的类型，局部高速率的沉积物供应回在湖侵期发育进积式准层序组。气候的变化也是层序发育的控制因素，在干旱期，湖平面变化和层序的结构主要受气候控制。

| 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. |
