黄海作为大陆架浅海，在地壳性质上仍属大陆型地壳．但整个黄海的结构、性质并不完全相同．在地质、地球物理场特征上黄海可分为南、北两个部分．五莲—青岛—朝鲜半岛的临津江为一条重要的结合带．此带以北，地球物理场特征基本与华北地块相同；此带以南，则与扬子地块的性质一致．同样，江绍断裂入海之后继续北上可追朔到光州地区，是区分扬子块体与华南块体的重要界线．各块体的地球物理场特征与本区的大地构造演化史、地壳上地幔结构及其动力学环境密切相关
The Yellow Sea, as a continental shelf, is still a continental crust in nature. However, the structure and nature of the entire Yellow Sea are not exactly the same. In the geological and geophysical field, the Yellow Sea can be divided into two parts, south and north. Wulian - Qingdao - Linjin River on the Korean Peninsula is an important combination belt. To the north of this zone, the characteristics of the geophysical field are basically the same as those of the North China block; the south of this zone is consistent with the Yangtze block. Similarly, the continued breaking of the Jiangsha fault into the Gwangju area after it broke into the sea is an important distinction between the Yangzi block and the South China block. The geophysical characteristics of each block are closely related to the tectonic evolution, the structure of the upper crust and its dynamic environment in this area
