In order to study the origin of NNE- or NE-striking Jiuquan prototype basins,which locate between northern Qilian orogene of NWW-striking and Alxa block, this paper analysed the tectonic style of Jiuquan prototype basin group, the basin fills, early Cretaceous volcanic rock and Cenozoic reversible tectonic. The author initively think that Jiuquan basin group is rift basin of NNE- or NE-striking, and it was resulted from continental tectonic-thermal event which took place in depth in early Cretaceous. During Cenozoic, the pigback thrust-napping of northern Qilian Mountains, which were caused by the squeenzing of India plate must have made southern part of Jiuquan basin group to become northern Qilian Mountains; at the same time, the squeezing action of India plate controlled the basin reversion, in the form of changing the NNE- or NE-striking normal fault which controlled the sedimentation system of secondary tectonic unit in Jiuquan basin group in early Cretaceous to be thrust fault. In a word, Jiuquan basin group was longer and wider in early Cretaceous than now.
