A comparison between the Late Mesozoic Dabie-Sulu orogenic belt and South hina in terms of their granite spatial-temporal distributions and stress fields. Earth Science Frontiers ,2011,18( 1) :009-014 Abstract: The in-s itu remelting theory of granite opens a new perspective for the study of the tectonic cause of the spatial and temporal distribution of the Late Mesozoic ( Late Jurassic-Early Cretaceous) granite in South China. By comparison, we found that there is a high degree of similarity and consistency in the spatial and temporal distribution of granite and the stress field in the Late Mesozoic between the Dabie-Sulu orogenic belt and its north vicinity (especially the Sulu orogenic belt and its north vicinity) and South China. That is, the granite distribution is mainly along the NE direction, turns from old to new from NW to SE, and is under the control of the same stress field caused by the high-speed subduction of the paleo-Pacific plate towards the Eura- sia continent. On the basis of this theory, we may conclude that the Late M esozoic ( LateJurassic-Early Creta- ceous) granite of the Dabie-Sulu orogenic belt and its north vicinity and the Late Mesozoic (Late Jura
