lang=EN-US>The North China Craton (NCC) is one of the oldest cratons in the world, with the age of the old crust up to ～lang=EN-US>3.8 Ga. It has a complicated evolution history and has recorded almost all the important geological events of the Earth. The main Early Precambrian geological events and key tectonic issues are as follows: Old continental nuclei and main crustal growth in the NCC took place at 2.7～lang=EN-US>2.9 Ga; By 2.5 Ga, the micro-blocks had amalgamated to form a coherent craton; the 2300～lang=EN-US>1950 Ma Paleoproterozoic mobile belts came into being; the 1800 Ma lower crust uplifted as a whole; and there occurred mafic dyke swarm, continental rifting and intrusion of orogenic magmatic association. In the period of Neoproterozoic and Paleozoic, the NCC was tectonically inactive but was affected by the Central Asian Orogenic Belt. The North China Craton probably experienced disruption and reconstruction in Mesozoic and belonged to the Circling Pacific Orogenic Belt in Cenozoic. The North China Craton has abundant ore deposits corresponding in age to the above important geological events.
