THE CHARACTERISTIC OF GEOPHYSICAL FIELD IN THE EAST CHINA AND ADJACENT REGIONS AND ITS TECTONICS SIGNIFICANCE

HAO TIAN-YAO; LIU YI-KE; DUAN CHANG (Institute of Geophysics, Academia Sinica, Beijing 100101, China)  
On the basis of the analysis for gravity field, magnetic field, electromagnetic tectonics and seismic data. the significance of geophysical field in the East China and adjacent region and its geotectonics evolution have been approached.The geophysical characteristic of the East China is that it shows different beltS from the west to the East and different blocks from the NOrth to the South. The East China is composed of the Eastuorth block, North China block, Yangtze block and South China blocks. They have different geological features and structures. They collided and pieced together in different geological periods. Therefore the geotectionic evolution of the East China can be shown by 5 stages.
