| 摘 要： | 本文根据已有的日本海区域重力场和莫霍界面分布资料和由地震Ｐ波速度层析模型转换的密度分布及其重力异常场资料作对比。分析和讨论了两者在日本海的重力异常场、深部地壳构造特征和日本海的扩张中心上的异同。并提出和探讨从日本海纵跨本州岛到太平洋的佐渡－伊豆高重力异常带。

| Abstract: | Based on the information and data of gravity field,distribution of Moho depth and density from velocity tomography modle of P-wave and comparing them each other,the features of gravity anomaly,deep structure and expanding Centre in Japan Sea and the difference have been analysised and discussed. The gravity high anomaly belt from Honshu Island to Sado-Izu has been described. |
