摘要
In order to reveal Cenozoic structure dynamics mechanism of Huanghua Depression, the authors made a comprehensive analysis of Cenozoic basin structure features of Huanghua Depression using the theory of Oilfield Structural Analysis. The result shows that the whole Paleogene strata of the Huanghua Depression can be regarded as a graben-horst structure system in the upper wall of Cangdong fault. The basin structure features are obviously different in different segments. The southern area consists of two graben fault-depressions whose structures are related to the attitudes of fundamental faults, the southern part of the middle area assumes a half graben system controlled by three SE-dipping normal faults, and the northern part of the middle area converts into a graben fault-depression. The structure of the northern area is mainly controlled by NE-and NW-trending faults and assumes a half graben or a graben fault-depression. Based on an analysis of structure features in Cenozoic basin of Huanghua Depression
