摘要:The North China block,the western portion of the Sino-Korean Craton,is rounded by Yanshanian in the north and Qinling-Dabie orogenic belts in the south.The widespread development of extensional basins in this block indicates horizontal extension or continued thinning of a previousely thickened,trnstable lithosphere throughout the Mesozoic.In this paper,we attempt to simulate numerically the geodynamical process of the basin formation by using the mountain-basin evolution system.We assume that the formation of numerous sedimentary basins in the North China block is the result of the crustal extension,which destructs rapidly the previously thickened crust.
