    摘要
  • 摘要: 本文利用P波初至和部分续至震相,研究了华南地区和边缘海的上地幔P波速度结构,并与已经得到的华北地区[1]、南北带、青藏高原的结果[2]加以比较,发现中国境内的地台与构造活动区之间,以及不同的准地台之间的上地幔P波速度结构存在明显的差异.这种明显的横向不均匀性的深度可达700km.作者对这种横向不均匀性,从大地构造演化的角度作出解释.

    Abstract: In this pater, the authors have studied the velocity structures of the upper mantle beneath South China and the marginal seas of China by using the first arrivals and some secondary arrivals of p-wave and have contrasted them with that in other regions: North China, Qinghai-Tibet plateau (Qing Zang Gaoyuan) and the North-South Seismic Zone. We have found that there are significant differences in velocity structure in the upper mantle not only beneath the stable platforms and tectonic-active zones, but also in different quasi-platforms. The lateral heterogeenity in velocity may continue to a depth of about 700 km. The authors try to explain this lateral heterogenity from the point of view of tetonic evolution in this paper.
