东南亚陆缘的卫重异常及其形成机制初探

PRELIMINARY RESEARCH OF SATELLITE GRAVITY ANOMALY AND ITS ORIGINAL MECHANISM OF CONTINENTAL MARGIN REGIONS IN THE SOUTH EAST ASIA

在东亚的陆缘地区。存在着一系列的陆缘弧。本文利用地面和根据GEMIOC地球模型的重力位球谐系数所计算的卫星重力资料,从地球动力学的角度探讨了其中几个陆缘弧的形成机制。重点探讨了我目东南沿海陆缘弧的重力异常特征及其形成机割。

There are a series of epicontinental ares in the marginal regions of the East Asia. The original problem of some epicontinental arcs is approached in this paper from earth dynamics angle according to practical bouguer anomaly and theorial satellite gravity anomaly, the latter is counted of gravitational potential spherical harmonie coefficient of GEMIOC earth pattern. The features and their original mechanism of gravity anomaly of the epicontinental arc in the Southeast China are the focal point in discussion.
