There are marked differences in petrogeochemistry between granulite xenoliths (Hannuoba) and granulite terranes (Xiwangshan and Manjinggou) in North China craton. The xenoliths are predominantly mafic in composition, whereas the terranes tend to be felsic in composition. Different epochs of rock formation, different depths of origin and different tectonic settings seem to be responsible for their diversities. Hannuoba granulite xenoliths are cumulates of the basaltic melts underplated in the lower crust associated with the extensional tectonics, and the geochemical compositions of the xenoliths are controlled by the proportion of pyroxene to plagioclase. The crustal contamination is not the only reason for Nb, Ta, U and Th depletion of Hannuoba granulite xenoliths. The basaltic melts might have experienced some fractional crystallization of Ti_minerals, which caused the Nb, Ta depletion, whereas metamorphism of granulite facies in the lower crust resulted in the depletion of Th and U in xenoliths. There exists the juxtaposition of different tectonics corresponding to the differences in geochemical composition of granulite terranes, which results from the extrusion uplift.
