连云港-苏州区域大剖面构造特征与变形机制
|
摘要
依据地震、重力、磁法、电法等地球物理资料及野外实测地质剖面、钻井资料等,对连云港-苏州区域大剖面进行地质-地球物理综合解释。根据区域构造演化以及动力学机制,并结合前人对下扬子区的研究成果,对连云港-苏州区域大剖面的主要构造特征、变形机制及典型构造样式等进行了分析研究。剖面存在两套方向相反的逆冲推覆体系,其变形强度由南北两侧向中间逐渐减弱,至中部泰州-安丰一线出现对冲带。剖面上典型的构造样式主要有压缩构造样式、伸展构造样式和负反转构造样式。
Based on seismic,gravity,magnetic,electrical geophysical information and field measured geologic sections,drilling information,a geological -geophysical interpretation of Lianyungang -Suzhou section was performed.According to the regional tectonic evolution,the dynamic mechanism and in combination with the predecessors' research on the Lower Yangtze area,the regional section of the major structural features,deformation mechanism and the typical structural styles were analyzed. There are two opposite directional thrust-nappe systems in the section.The intensity of deformation of the section is weakened to middle from both sides of the north and south gradually,to the central Taizhou -Anfeng Region there is an appearance ramp tectonic framework.There are compression tectonic style,extensional tectonic style,negative inversion tectonic style in Lianyungang -Suzhou section.
