Abstract: This paper analyzes the regional tectonic setting in Yanqi basin, and it is concluded that present tectonic framework is controlled by approximate east-west faults and north-west ones. Based on palaeomagnetic data, the peripheral tensional structure, intrabasinal residual normal fault, high geothermal gradient and the characters of sedimentary. Study shows that Yanqi Mesozoic basin is an extensional fault basin.

Key words: Yanqi basin, Mesozoic, fault-depression basin
