Geologic feature and tectonic evolution in the South Yellow Sea

South Yellow Sea is mainly located on the Yangtze platform, which is a sequence residual basin that has been migrated and superimposed since the late Proterozoic, and has been transformed many times to make the original appearance incomplete. South Yellow Sea Basin has a complex process of formation and evolution. South Yellow Sea has the characteristics of north-south block and east-west zoning. The fault is dominated by the direction of NEE, NE and NW. The fault zone has large extension length and staggered structures in all directions, which is featured by multi-type and multi-order. The main magmatic rocks in the South Yellow Sea are Yanshan period magmatic rock, and the distribution of rock mass is controlled by NE fracture, and has the characteristics of multi-stage activities with large and frequent strength. Since its formation, the South Yellow Sea region has experienced six tectonic movements, among which Yizheng Movement, the First Act of Wubao Movement, and Sanduo Movement are three major tectonic movements. The structural relationship and interaction between the Sino-Korean Block and Yangtze Block as well as Yangtze Block and South China Block, would provide important insights to the formation and evolution process of South Yellow Sea Basin, and the activity of Eurasian plate and the interaction between the surrounding plates.
