ZHOU Zuyi, DING Xiao, LIAO Zongting, JIN Xingchun. FORMATION OF MARGINAL BASINS AND ITS IMPLICATION TO THE TECTONIC EVOLUTION OF SOUTHEAST CHINA[J]. Advances in Earth Science, 1997, 12(1): 7-14.
Although a large variety of mechanisms have been proposed to account for the formation of marginal basins, including “entrapment” origin, back arc spreading and intraplate stress propogation, etc., no solution has ever reached for the formation and evolution for marginal basins in the western Pacific. The study of marginal basins should take into account the mechanisms for continental deformation, thus constitute a 3-D approach to the problem. Recent contributions in the study of marginal basins also shed new light in the study of tectonic evolution of Southeast China. Cautions should be taken in the identification of ancient volcanic arcs, subduction zones and the reconstruction of ocean basins. The combined effect of NNE trending transform faults related to Paleo tethys and the movement of Paleo Pacific plates play a significant role in the formation of huge Mesozoic igneous activities. Transition from transform fault to subduction system constitutes a unique form of continental accretion for Southeast China and its adjacent areas. Sediment record in the related basins will provide substantial information for the related continental collision and mountain building and erosion process.
