The North China Craton (NNC) is generated by amalgamation of continental nuclei, terranes, block and united blocks. According to tectonostratigraphy, geochronogy, mineralization, geochemistry and geophysics, the NCC can be divided into eight Precambrian blocks (united block or terrane) and two Mesozoic-Cenozoic basins which are Erdos and North China basins. The existing rock records show that paleo-continental nuclei is mainly formed in Paleo-Middlearchean Era during which formation of the early greenstone is not precluded; granite-greenstone terranes were mainly formed in Neoarchean and most of the greenstone terrane were formed around the margin of the nuclei during which the crystallized basement of NNC is formed; united blocks were mainly formed during Paleoproterozoic Era by amalgamation of blocks or terranes.
