Abstract We carried out integrated geological, geochronological and geochemical studies on typical early Precambrian areas of the North China Craton, such as Anshan-Benxi, eastern Hebei, western Shandong and Yinshan, and synthesized the general geological records of the Archean basement relating to Archean crust formation and evolution of the North China Craton. This study also revealed that the Ordos basement was involved in a widespread late Paleoproterozoic tectono-thermal event. We defined and outlined three ancient terranes containing abundant 3.8~2.6 Ga rocks for the first time in the North China Craton, namely the Eastern Ancient Terrane, Southern Ancient Terrane and Central Ancient Terrane.
