| Abstract: | Based on the analysis of structure controlling sedimentation and sedimentation responsing to structure, the coupling relationships are studied between the structure and the sedimentation in the north of Jizhong Basin during Paleogene: (1) Fault-block rotation controls the provenance of the depressions and the spatial configure of the depositional facies. (2) Circum-axis tilt controls the migration of the depositional center. (3) Differential uplift of basement rock controls the sedimentary segments of the depression. (4) In the transgression, the sedimentation displays strongly onlap which shows the basement to accelerate subsidence. (5) In the regression, the sedimentary sequence displays coarse-upward which shows the basement to decelerate subsidence.sediment |
