| 摘 要： | 东营凹陷古近纪控盆断层形态经历了早期(基本上对应于古近纪孔店组沉积时期)板式、中期(古近纪沙河街组四段到沙河街组三段早期沉积时期)铲式和晚期(沙河街组二段到东营组沉积时期)坡坪式3个阶段的演化,而断层的活动强度存在迁移性。古近系裂谷盆地各演化阶段沉积地层的空间展布与主要断层的走向基本一致,断层活动控制了盆地的沉积作用,与边界断层的演化相对应。东营凹陷古近纪盆地经历了早期旋转半地堑、中期滚动半地堑和晚期复式半地堑3个演化阶段。

| Abstract: | The shape of the Palaeogene basin-controlling faults of Dongying sag had evolved from planar in the early period(basically corresponding to the deposition of the Kongdian Formation),to listric in the middle period(deposition of the fourth member to the Lower third member of Shahejie Formation),and finally to slope-flat in the late period(deposition of the second member of Shahejie Formation to Dongying Formation).The intensity of basin-controlling fault activity in Dongying sag shows a left-lateral feature.The spatial distribution of deposits is basically consistent with the strike of main faults in different evolutionary stages of the Palaeogene rifted basin.The fault activities controlled the sedimentary process.Corresponding with the evolution of boundary faults,the Palaeogene basin in Dongying sag had gone through the early rotation half-graben,middle rolling half-graben,and late compound half-graben. |
