| The Division of South China Continent into Different Blocks Based on Geophysical Evidence and Comparison of Geochemical Features in Different Regions |
| In this paper, the South China continent is divided into three blocks, namely Yangtze block, Huaxia block, and Southeast Coastal block, on the basis of the data from deep seismic sounding, aeromagnetic surveying, and electromagnetic sounding. The apparent magnetization was calculated. The magnetic features of different regions in South China were studied according to the distribution of apparent magnetization. In addition, the boundaries of the regions were delimited and verified by using the data from deep seismic sounding and electromagnetic sounding. The boundaries of the regions are regarded as the boundaries of the blocks in South China. Therefore the results from the above study are quite objective. The authors made a brief comparison between these results and the data obtained from isotopic geochemistry of granitoids in South China so as to show that the division of the continent into different blocks is constrained by geophysical and geochemical data. |
