根据古地磁、古生物地理和地质构造分析，东亚大陆在中生代中晚期至新生代初期大幅度向南运动；新生代中晚期以来大幅度向北运动。运动学模式发生巨大转变的时期，大致在始新世与渐新世之间，这与全球运动学和动力学发生的重大改组的时间相一致。由此提出大陆后退这一新的南海形成演化的运动学模式。 According to the analysis of paleomagnetic, paleontological and geological tectonics, the East Asian continent moved greatly to the south from the middle and late Mesozoic up to the early Cenozoic. Since the middle and late Cenozoic, it moved northward to a large extent. The period of dramatic transformation in kinematic patterns, roughly between Eocene and Oligocene, is consistent with the time of major restructuring of global kinematics and dynamics. From this, we propose the kinematic model of continental evolution, a new South China Sea evolution.
