摘要
收集整理了我国近20年来古大陆再造研究和古大陆再造编图的新进展、新成果、新方法,通过整理并筛选最新的华北块体、扬子块体和塔里木块体的古地磁数据,辅以最新的地质依据,分析三大块体古生代以来的运动特征以及主要块体之间(华北与扬子、华北与塔里木、塔里木与哈萨克斯坦)的拼合碰撞时代。
Paleocontinent reconstruction is one of the hot issues in earth sciences of the world. A brief review is made in this article on the progress of paleocontinent reconstruction research in China, with emphasis on new ideas, new results and new methods developed in the past 20 years. Based on the palaeomagnetic and geological data from the north China Block, Yangtze Block, and Tarim Block, the movement of the three blocks since the late Paleozoic was carefully reconstructed. Special attention is given to the collision and/or merging of the main blocks, such as the merging between the North China and the Yangtze blocks, the merging between the North China and Tarim blocks, as well as the merging between the Tarim and Kazakhstan blocks.
