In terms of geodynamics, this area has always been a hot topic of research. This paper mainly studies the rock-layer structure and geodynamic mechanism of the eastern sea area of China and its neighboring areas. This study adopts seismic waveform processing methods and geophysical and geochemical analysis techniques, combined with existing data, to explore the rock-layer structure of this area in depth. At the same time, through comprehensive analysis, it explains the regional deformation characteristics and their sources.The research focuses on two aspects: firstly, to clarify the rock-layer structure of this region, including rock type, thickness, and horizontal distribution, it uses measured 精品文档---下载后可任意编辑reflection seismic profiles and detects geophysical characteristics...
