中国东部及其邻域地球物理场特征与大地构造意义

在分析中国东部及其邻域海陆地区的重力场、磁场、电性结构与深地震测深资料的基础上，探讨了地球物理场的大地构造意义及大地构造演化．指出中国东部及其邻域具有东西分带、南北分块的特征，它是由不同结构性质的东北、华北、扬子和华南四大块体组成，并于不同时代碰撞、拼合到一起，经历了五幕演化史．

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

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.
