In order to better understand the block rotations in the Northeast China and adjacent regions, the authors analyzes mid-Early Cretaceous, late-Early Cretaceous and Late Cretaceous paleomagnetic data, respectively. The eastern Liaoning and Korean peninsula is rotated about 11° clockwise relative to the North and South China blocks (except Korean peninsula, eastern Liaoning and Jiaodong peninsula) during mid-Early Cretaceous and late-Early Cretaceous. No significant rotations occurred since Late Cretaceous between Korean peninsula and the North and South China blocks. About 13 counterclockwise rotations of the western Liaoning with respect to the North and South China blocks took place since mid-Early Cretaceous. These rotations are accommodated by lithosphere thinning and extension beneath the Northeast China and adjacent regions, which resulted from the strong upwelling of asthenosphere caused by the subduction of the Pacific plate.
