| 英文摘要 | A study on five representative wide-anger seismic profiles in South China is completed. The fine velocity distribution patterns are fitted with the travel times of first arrive Pg waves. Combining with other geophysical data and geological data, we make a synthesis explanation for the tectonics of basement and cover. It is proved that some fault basins infilled with Mesozoic volcanic rock above the basement are distributed in the eastern region of Zhejiang, Fujian and Guangdong provinces and the thickness of the volcanic rock layer is 1000-4000m. In the regions of western Zhejiang, southern Anhui, Hunan and Jiangxi Provinces, the basement surges obviously and the cover is mainly Palaeozoic group, and some Mesozoic Cretaceous smaller basins controlled by boundary faults develop there. The Chuxiong basin in western South China is a deep depression with complex structure, in which the thickness of Jurassic-Cretaceous systems is over 10km. This basin is divided into two parts of eastern ascent and western depression, and the western depression is farther divided by a center uplift into two smaller deep depressions. Some Main faults in the researched region are reflected clearly in the contour velocity diagrams. Jiangshan-Shaoxing fault, Lianhuashan fault and Wuchuan-Sihui fault in the eastern region, and Chenghai fault, Luzhijiang fault in the western region are all the important tectonic boundaries, also flock basement faults are primarily the boundaries of the basins and the uplifts. |
