Abstract: Many multi-disciplinary scientific projects have been conducted in the last decade, aimed at tectonic evolution of craton and ancient orogen, their deep-level structures, reconstruction and correlation of Proterozoic supercontinent, crustal nature of early continents and their growth. The development of geological techniques，such as isotopic chronology，especially，zircon U-Pb age datings，seismic reflection，determination of P-T and palaeomagnetic measurement，played an important role for the understanding of Early Precambrian geology. As regional geological data for different cratonic which cover the components and tectonic division of early continental crust，tectonic evolutionary history of Archean craton，boundary between Archean and Proterozoic，Proterozoic orogen networks and collage among the cratons，exposed cross-section of lower contentinal crust and their assemblages etc. The major questions associated with Early Precambrian geological evolution of North China Carton(NCC)include tectonic relationship between north China granulite-facies belt and other parts of NCC basement, tectonic division of the basement，crustal nature of Precambrian metamorphic terrains，relavent major tectono-therma1 episodes， correlation of NCC with other typical cratonic blocks etc.
