The basin-and-mountain system of Northeast China formed and developed mainly in the late stage of Late Jurassic-Neogene, involved two processes of tectonic development: the late Late Jurassic-Early Cretaceous small basin-and-mountain stage and the Late Cretaceous-Neogene big basin-and-mountain stage. The basin-and-range stage originated in the Zhangjiakou stage developed in the Yixian-Jiufotang stage, withered in the Shahai-Fuxin stage, and finally ended in the Zhanglaogongtun stage. It is more possibly the result of super mantle thermal zone and mantle plume action together with West Pacific Plate subduction, under the background of East Asian multi-direction plate convergence.
