The Su-Jiao orogenic belt is the eastern part of the Central Mountain System of China. Recent studies on its erogenic system indicate that the Su-Jiao erogenic belt is a complex orogenic belt which suffered at least 3 orogenies of different mechanisms in the Mesoproterozoic, Neoproterozoic and Triassic respectively. The Meso-Neoproterozoic orogenies belong to the Wilson cycle on the plate margins. The belt is a part of the Late Mesoproterozoic supercontinent Rodinia. The Triassic orogeny belongs to the re-orogeny of the non-Wilson cycle. Delamina-tion of mountain roots occurred after both the Wilson and non-Wilson cycles in the Su-Jiao erogenic belt. The large-amplitude isostatic uplift of mountains, magmatic activities and basin-forming and mountain-making in the upper crust, all indicate the general significance of delamination in the development of erogenic belts. 相似文献
