太平洋西缘分布着一系列边缘海盆。这些边缘海盆形态各异 ,构造多变 ,是地球上独特的构造—地貌单元。通过分析边缘海盆的地质和地球物理特征 ,并从地幔运动引起的地质作用出发 ,提出西太平洋边缘海盆是由地幔向东的蠕散和流动促使地壳拉张、变薄和破裂所致
A series of marginal basins are distributed along the western edge of the Pacific Ocean. These marginal basins vary in shape and structure and are unique tectonic-geomorphological units on Earth. Based on the analysis of the geologic and geophysical characteristics of the marginal basin and the geologic role caused by the mantle movement, it is proposed that the easterly westerly basins in the western Pacific Ocean cause the crustal extension, thinning and rupture caused by the creep and flow of the mantle to the east
