| 英文摘要 | In this paper, the shear wave velocity structures beneath nearly 50 stations in North China were analyzed down to a depth of 800 km. The results show that there exist large differences among different tectonic units. The velocity increases steadily with depth in stable blocks, but the velocity structures become complicated beneath tectonic belts. Even in the same tectonic unit, the structure is apparently dissimilar at different segment, such as the Taihangshan tectonic belt, which reflects that different tectonic units and segments experienced their respective geological evolutional. histories. The structures beneath the area around Bohai Bay and its neighboring indicate that the mantle asthenosphere in eastern China is shallow, thick and with low velocity values, which illustrates the character of up-welling mantle. But, no uniform high velocity or low velocity bodies in similar depth or with similar thickness were found in the asthenosphere or in much deeper mantle under the stations in eastern China, so probably, no any lithosphere or lower crust had been detached into the mantle, which provides a deep geophysical constraint on the dynamic mechanism of the lithospheric thinning in eastern North China. |
