摘要

摘要: 东亚陆缘新生代盆地几何特征具有相似性,呈以NNE、NEE至EW向断裂为边界的准菱形。它们形成的运动学具有相似性,形成时两侧块体作近NS向分离。它们形成的动力学具有相似性,形成时区域性最小主应力作近NS向展布。现行的"挤出构造"理论不能解释东亚陆缘诸多的构造现象。

Abstract: The Cenozoic basins of different magnitudes in East Asia continental margins are similar and self similar in shape.They are para-rhomb,preferentially delimited by NNE and NEE as well as EW tending faults.During formation,they had similar kinematics with their bilateral blocks being pulled apart in nearly NSdirection;they were also characteristic of similar geodynamics,and the regional minimum main stress trajectories had been oriented nearly NS,which has resulted from collision between Eurosia plate and indianplate,and dextral shearing along the boundary between Eurosia and Pacific plate.Many tectonic phenomena in Cenozoic basins of East Asian continental margins can not be explained by the current theory of"Collision-Extrusion Tectonics".
