摘要
用卫星雷达测高确定海面高度可以容易地转换成重力异常。南海应用密轨道的GEOSAT/GM和ERS- 1卫星测高数据获得了高分辨率的重力复盖。在这个新的重力图上揭示出许多有意义的、过去未能清楚显示的构造特征 ,其中包括扩张脊 ,转换断层 ,岩石层弹性板厚度 ,大陆边缘性质 。
The sea surface heights determined by satellite radar altimetry are easily converted into gravity anomalies. Satellite altimetric data from closely spaced Geodetic Missions of both GEOSAT and ERS-1 were combined to achieve the highest resolution gravity coverage over the South China Sea region. Many interesting and previously uncharted features are revealed in this new gravity map including spreading ridge, transform faults, elastic plate thick ness of lithosphere, behaviors of continental margins, and new sedimentary basins.
