苏北-南黄海盆地地震构造基本特征

Seismotectonic Characteristic of Northern-Jiangsu-Southern-Yellow-Sea Basin

  • 摘要: 苏北-南黄海盆地位于下扬子地块,构造演化较为复杂,其构造范围及属性尚存在争议,区域构造特征与构造演化历史对区域现今地震发生有着重要影响。通过对区域地质与构造演化的分析,提出下扬子地块构造演化独立于扬子地块,厘定苏北-南黄海盆地范围,阐述了区域构造基本特征以及对现今地震构造有重要影响的构造事件过程,重点探讨区域内NW向构造的形成与演化特征及其对中强震的重要意义。

     

    Abstract: The Northern-Jiangsu-southern-Yellow-Sea basin is located in the lower Yangtze block, its tectonic evolution is complicated, and its tectonic boundary and characteristic is still controversial.Regional tectonic characteristic and tectonic evolution have significant influence on regional seismic activity today. Through analysis on regional geological and tectonic evolution, we consider that the tectonic evolution of lower Yangtze block is independent of Yangtze block.This paper presents the boundary of the basin, describes basic regional tectonic characteristic and processes of tectonic events that has significant influence on seismictectonic nowadays, and mainly discusses the formation and evolution characteristics of NW-trending tectonics in this region and its significance to moderate and strong earthquakes.
