Abstract:

Based on the principles to respect believable and higher precise paleomagnetic data of blocks and to pay attention to the similarity of paleobiogeography and the coordination of tectonic evolution, the paleomagnetic data of Chinese continental blocks and adjacent areas for Paleozoic and Triassic were collected, the Chinese continental blocks were laid up on the reconstruction of global paleo-continents with similar scale. Thus, it can be clearly recognized that the global continents located at near equator and southern hemisphere, showed the characteristics of range along latitude; Chinese continental blocks still located among the Laurentia, Siberia and Gondwana in Paleozoic; following the fast moving of Siberia plate to northwards, the amalgamation in north-south direction at the western parts of Laurentia and Gondwana, subducted the Iapetus and Rheic Oceans, until to form the uniform Pangea in the late stage of Paleozoic; however Australia and India plates in eastern Gondwana move and disperse gradually to southwards, to extend crust and form the Paleo-Tethys Ocean; the Chinese continental blocks and adjacent blocks still located in Paleo-Tethys Ocean, preserved the status of dispersion, gradually moving to northwards, showed the characteristics of range along north-south orientation, until Carboniferous and Triassic a series of local collisions happened in Tianshan-Hing'anling, Kunlun, Qinling-Dabie, Jingshajiang and Shaoxing-Shiwandashan zones, thus the most part of Chinese continental blocks amalgamated to Eurasia continent.
