摘　　要：Cretaceous rift basin evolution was an important part of the tectonic history of northeast Asia in the late Mesozoic.Three types of rift basins are identified—active,passive and wide rift basins—and they developed in different regions.Passive rift basins in the eastern North China craton are thought to be the consequence of crustal stretching and passive asthenospheric upwelling.Wide rift basins in the eastern Central Asian orogen are assumed to originate from gravitational collapse of the thickened and heated orogenic crust.Active rift basins in the northern North China craton are attributed to uprising of asthenospheric materials along a lithospheric-scale tear fault.Slab tearing of the sub ducting paleo-Pacific plate is postulated and well explains the spatial distribution of different types of rift basins and the eastward shifting of magmatism in the northern North China craton.The Late Cretaceous witnessed a period of mild deformation and weak magmatism,which was possibly due to kinematic variation of the paleo-Pacific plate.
