Abstract Research purposes: There are much mesozoic magmatic rocks in the north of the northern China Craton and many interpretations on the cause for their formation． This paper researches the establishment，the source and the dynamics background of the mesozoic magmatism of the each magmatic rock in this area with the Sr － Nd － Pb isotopic tracing．

Research conclusions:The mesozoic magmas are mainly originated from the low crust and middle crust with small amount of the mantle materials into the intermediate magmas． The many evidences showed the magmatic activity in the Indosinian and early Yanshanian epochs were developed under the geodynamic setting of synorogenic thickening crust and were the activated productions of the crust substance in the basement． The middle and late Yanshanian magamatism were probably formed during the postorogenic collapse and it was closely related to the space － time of the mantle underplating． The mixed effect of the zone batch partial melting of the crust with different depth and the end member magma caused the formation of several kinds of magmas in the same period．

Key words： Northern China Craton magmatism mesozoic isotopic geochemistry
