%X The northern North China, tectonically composed of a Phanerozoic orogen and a Precambrian craton, witnesses a panoramic scenario of continental crustal accretion and reworking in the model of plate tectonics during the Paleozoic times. It is driven by rifting-spreading-extinction cycle of paleo-oceans and subduction-collision-extension processes at convergent plate margin, with a series of the associated magmatic events produced. These magmatic expressions constitute an excellent window through which the relationship among crust-mantle interaction at convergent plate margin, continental crustal evolution and large-scale metallogenesis can be fully characterized. Based on an overview on the geochronological and geochemical data concerning the Paleozoic magmatic rocks from the northern North China, the paper outlines the evolved geodynamic scenarios inherent in these magmatic sequences, envisages multi-stage crustal accretion and reworking mechanism during the Paleozoic continental construction in northern North China and ends with a tentative evaluation of promising magmatic and tectonic reservoirs for metallogenesis.
