中国东部中生代开始、展现了一个历史性的伟大变革,结束了古生代南北分野的局面,进入一个以滨太平洋方位为主体的构造格局。在这个重大的变格作用中,大陆东缘新生的一系列北东、北北东向穿陆的大型平移断裂及其进行的左行剪切运动起了实质性的作用。反映了东亚大陆与太平洋盆相对运动的开始及东亚大陆真实边缘的产生。 断裂的变格作用既有控制作用又有改造作用;后者使老岩层、老岩相带、老岩体等在断裂剪切的旋转应变场中产生新的形态、新的面理及新的方位。 中生代以来的变格作用,使北北东一北东向构造格局取代了早期近东西向的格局,使阿尔卑斯体制取代了前阿尔卑斯体制,使滨太平洋构造域取代了原有的古亚洲构造域。
The beginning of the Mesozoic Era in eastern China has shown a historic and great change, ending the Paleozoic South-North divide and entering into a tectonic framework dominated by the Binhai Pacific. In this major transformation, a series of northeastern and northern-northeaster continental transgressive large-scale translational faults and their left-lateral shearing movements played a substantial role in the new continental margin of the continental margin. It reflects the beginning of the relative movement between the East Asian continent and the Pacific basin and the real edge of the East Asian continent. The deformation of the fault has the function of both controlling and remolding. The latter makes the old rock formation, the old lithofacies belt, the old rock mass and so on produce a new shape in the rotational strain field of the fracture and shearing, the new surface and the new position. The transformation from the Mesozoic to Mesozoic led to the replacement of the early near-western pattern by the structural pattern of north-north east-north east, which replaced the pre-Alpine regime with the Alps system and replaced the original Pacific tectonic domain with the former Pacific tectonic domain.
