| 摘 要： | 在河北武安大淑村刘家沟组布采点１３个，采样９１个，进行了古地磁学研究，研究结果表明，华北陆块与陆块在早三叠世时尚未形成一体，自上三叠世至今，华北陆块以反时针，扬子陆块以顺时针，各自旋转了数十度。

| Abstract: | samples were collected from 13 sites in Liujiagou Formation, Dashucun, Wuan, Hebei Province. Paleomagnetic studies of them show that North China block and the Yangtze block were not integrated into one in the Early Triassic period. Ever since then the North China block and the Yangtze block each rotated tens of degrees, with the former turning counterclockwise and the latter clockwise. |
