摘要

East of the Ural Mts. and north of the Kunlun-Qinling-Dabie mountain system in NE Asia there are three large old cratons, that is, the North China (Huabei), Siberia and Tarim old cratons (Fig. 1). They became such stable blocks after they were accreted and consolidated around the Archean continental nuclei 1.8, 1.6 and 0.8 billion years ago, respectively, and then were amalgamated to form an important part of Paleo-Asia.
