| Abstract: | In the last decade, deep seismic sounding (DSS) of profiles several ten thousand kilometers in length has beenconducted in the mainland of China. A lot of results published in Chinese were compiled and a map of Mohodepth was presented in this paper. Coverage of DSS profile is not uniform,and is lacking in some areas, especiaLly in the western part of China. In this case,the results from dispersions of seismic surface waves and other materials were considered. According to the Moho depth, the mainland of China can be divided into eight crustalblocks.The Moho depth is uniform and varies little inside the same block, while it changes abruptly from oneblock to another. The Tibetan Plateau is characterized by a thickest crust in the world. It may be due to thepenetration of indian crustal materials into the Tibetan crust or upper mantle. Deeper Moho in the neighbouringareas of Tibet may also be effected by the complicated collision processes between the two continents.Thin crusto f the North China Plain is considered to be related to the magmatic activities in the lower crust and uppermantle. While the crust of the eastern part of SOuth China may be due to the accretion of terrain from the oceanislands. |
