摘要:

下扬子地区地处扬子板块东部,其构造变形特征研究具有重要意义。综合利用区域地质、地震、钻井和地球物理等多方面资料,对下扬子地区断裂、地层发育特征精细解释,建立了贯穿研究区的两条区域地质剖面,即宿迁绍兴大剖面和连云港苏州大剖面。研究表明:下扬子地区可划分为6个一级构造变形单元,依次为苏北胶南造山带、苏北冲断区、南北对冲带、苏南冲断区、浙北冲断区和江南造山带,并可进一步细分为14个二级构造变形单元,这些明确表现出本区中、新生代对冲构造变形特征;两条区域大剖面表现出了挤压、伸展、反转等3类典型构造变形样式,具体可分为5亚类、10小类。

关键词: 下扬子, 构造变形, 对冲构造, 区域大剖面, 断裂

Abstract:

Located in the eastern part of the Yangtze plate, the tectonic deformation of the Lower Yangtze is of geological significance. Based on the regional geological data, seismic data, well logging, and geophysical data, the stratigraphy and faults are finely interpreted, and two regional geological profiles are established throughout the study area, namely Suqian-Shaoxing profile and Lianyungang-Suzhou profile. The Lower Yangtze region is divided into 6 level one tectonic deformation units, followed by Subei-Jiaonan orogenic belt, Subei thrust area, north and south thrust belt, Sunan thrust area, Zhebei thrust area, and Jiangnan orogenic belt, and it can be further divided into 14 level two tectonic deformation units, which clearly represent the Mesozoic-Cenozoic tectonic deformation of the Lower Yangtze region. There are three typical tectonic deformation styles out of the two profiles, including compression, extension, inversion, which can be divided into 5 sub-classes and 10 small classes.

Key words: Lower Yangtze, tectonic deformation, hedge structure, regional geological section, fault
