摘　　要：在概略介绍罗迪尼亚和冈瓦纳超大陆最新研究成果的基础上 ,重点介绍了中国华北、塔里木和扬子等三个克拉通前新元古代大陆地壳演化的主要特征 ,以及塔里木和扬子克拉通新元古代重大热构造事件序列和年代格架。提出塔里木和扬子克拉通新元古代地质历史具有较大的相似性 ,而与华北克拉通有明显差异。华北克拉通未出现与罗迪尼亚超大陆汇聚和裂解作用有关的、强烈的新元古代热构造事件群。根据现有的古地磁和地质资料 。In this paper, after briefly introducing the new advances in the research of the Rodinia and Gondwana supercontinents, we emphatically demonstrate the characteristics of the North China, Tarim and Yangzi Cratons in the pre-Neoproterozoic period, and the sequence and time framework of Neoproterozoic major events. We propose that there is marvellous similarity between the Neoproterozoic history of the Tarim and Yangzi Cratons, however, they are different from that of the North China Craton. In the Rodinia, the Tarim and Yangzi were neighborhood to Australia, but the North China Craton might have been close to Siberia. Meanwhile there was no very strong Neoproterozoic thermo-tectonic events that were related to assembly and breakup of Rodinia occured in the North China Craton . On the basis of present paleomagnetic and geological data, the relationship and the possible position of the three cratons of China to the Rodinia supercontinent are proposed.
