活动的最新构造系从西、北、东三面包围着太平洋。根据板块构造理论,这些构造系的发生和发展取决于大洋板块向大陆型或过渡型地壳的边缘板块下的俯冲活动。俯冲作用解释了岛弧(大陆边缘)-海沟形成的构造动力力偶,以及岛弧的钙碱性火山分异作用和向大陆倾斜的震源带的形成。为了搞清上述现象反映的环太平洋现代构造演化动力学的完整图景,作者分析和总结了晚第四纪的新构造断裂、地形变和现代地震的资料。首先研究了沿大陆边缘或岛弧延展的大断裂的活动性。这些断裂一般认为直接反映了这一地区主要的岩石圈板块运动特征和相互关系,它们往往很陡,并且位移是平移型或多半是平移型的。新西兰的阿尔卑斯断裂、菲律宾和中国台湾的纵向断裂、日本的中央构造线、阿留申岛弧西部的末端缝合线、阿拉斯加中央
Activities of the latest structure from the west, north and east surrounded by the Pacific Ocean. According to the theory of plate tectonics, the occurrence and development of these tectonic systems depend on the subduction of the oceanic plate under the marginal plate of the continental or transitional crust. The subduction explained the tectonic force couple formed by the island arc (continental margin) and the trench, as well as the calc-alkaline volcanism differentiation of the island arc and the formation of the source zone inclined to the mainland. In order to find out the complete picture of the evolution dynamics of modern Pacific Rim reflected in the above phenomena, the author analyzes and summarizes the data of Neotectonic faults, topographic changes and modern earthquakes in the Late Quaternary. First, we study the activity of large faults extending along the continental margin or island arc. These faults are generally considered to directly reflect the major lithospheric plate motion features and interdependencies in the area, which tend to be steep and displacements are either translational or mostly translational.
