Abstract: Palaeogeographic reconstruction in small scale is one of the most effective method for discussing tectonic-basin evolution in geological time. Recent progresses in lithofacies paleogeographic study on South China provide new clues on the key geological problems in early Paleozoic. The results of our study show that there is no critical tectonic-basin boundary between the Yangtze and Cathaysia block in early Paleozoic, which has a continuous distribution of sedimentary facies in time and spaces. These lines of evidence deny the presence of Huanan remnant-ocean basin in early Paleozoic, and, with the coupled evolution of paleogeography in successive stages, support the hypothesis of one solid South China Plate. The results also support a mountain-basin coupling process inside of South China Plate, instead of transition from passive continental margin to foreland basin system. This process can be considered as re-cratonization of South China Plate in Early Paleozoic.
