Abstract
The Mesoproterozoic mafic dyke swarms are extensively distributed in the ce ntral North China Craton(NCC) including North Shanxi, Wutai and Luliang are as, which are not deformed and metamorphic but high magnetic, so the dyke s warms become the mark to compare the high metamorphic rock areas in magneti sm. Based on the analysis of paleomagnetism of mafic dyke swarms in North S hanxi, Wutai and Luliang areas, NCC inclined southward about 18 degrees so that North Shanxi lifted up and rotated 10 degrees left to Wutai area. The dyke swarms in Luliang developed later than in North Shanxi and Wutai area. The NNW-trending and WNW-trending dyke swarms developed in Luliang while t he North China Plate moved northward consistently so that the paleomagnetis m of dyke swarms in Luliang is greatly different from North Shanxi and Wuta i area.
