黄骅拗陷孔店凸起形成演化的动力学机制
Dynamic mechanism of the tectonic evolution of Kongdian salient in Huanghua depression, China
摘要
Abstract
By analyzing the seismic section of the Kongdian salient and its surrounding areas, this paper cognizes the tectonic framework characteristics of the Kongdian salient and overlying strata and approaches the tectonic evolution history of the Kongdian salient. The low salient began to gestate in the deposition period of the lower Kongd 1 formation, the salient had a large scale uplifting in the deposition period of the higher Kongd 1 formation, after the short deposition in the deposition period of Shahejie Formation, the Kongdian salient began to uplift again in the deposition period of Dongying Formation. Since the Neogene, the Kongdian salient occurred settlement again. So, in Cenozoic, the Kongdian salient experienced four stages: uplifting-subsiding-uplifting-subsiding. To the dynamic mechanism of the tectonic evolution of the Kongdian salient, firstly, this paper makes the comparative analysis of the settlement curve of the Kongdian salient, the settlement curve of the basement, the settlement of the extensional amount and the extensional rate. Combined with the morphological characteristics of the Kongdian salient and its tectonic framework characteristics, the authors preliminarily have an idea that the formation and evolution of the Kongdian salient are due to the extensional movement and the strike-slip movement of the Cangdong fault and the Xuxi fault, and also, have a certain relationship with the occurrence of the main fault (Cangdong fault).关键词
