作者将中国大陆边缘按演化历史分为两类,一类是形成于巨板块时期的以现今的东西分带面目出现的大陆边缘,另一类是作为潘基亚大陆边缘组成部分的以南北分块面貌出现并受前者东西分带格局迭加的大陆边缘.二者一起构成了中国大陆边缘的基本网格格架.变格运动使上述条和块共同进入了新的构造体制,陆壳以敛合为其主要特征,表现为多层次的盖层推掩和基底拆离.作为一种薄壳构造,由于不存在洋壳,块与块之间发生“干挤”,所以不存在象阿尔卑斯地区所具有的那种典型的诸如“鸟头状”的特征.显然,阐明中国大陆边缘需要进行其演化史和动力学方面的研究.
The author divides the margins of the Chinese mainland into two types according to their evolutionary history: the first is the continental margin formed by the present-day zoning along the giant plateau and the other is the north-south divide The appearance of the block and the continent edge superimposed by the former’s east-west zoning pattern together constitute the basic grid framework on the fringes of the Chinese mainland. The transformative movement brought the above-mentioned blocks and blocks together into a new structural system, As its main feature, is manifested as multi-level capping and basement detachment.As a thin shell structure, there is no “dry squeeze” between the blocks and the blocks due to the absence of the oceanic crust, Has the typical feature of something like “bird’s head.” Clearly, clarification of the Chinese mainland’s margins requires a study of its evolutionary history and dynamics.
