摘　　要：This paper introduces the result of studying on paleomagnetism of 91 specimens from 13 sites from Liujiagou Formation in Dashu Village, Wu ’an city, Hebei Province. The result reveals that North China block (NCB) was not united with Yangtze block (YB) in the Early Triassic. From the Early Triassic to now, NCB has rotated 30.0° counterclockwise, but YB has rotated 45.1° clockwise.This paper introduces the result of studying on paleomagnetism of 91 specimens from 13 sites from Liujiagou Formation in Dashu Village, Wu ’an city, Hebei Province.
