An Approach to the Accretion of the North China Block and the Formation of the Continental Crust

This paper deals with the formation and evolution of the North China continental crust and the controls of palaeotectonic movements on the sediments within the North China block on the basis of the study of the cycles in the sedimentary profiles and palaeogeography and ancient sediments within the block. Three stages for the formation of the continental cust have been distinguished, which exerted a tremendous influence on the biospheric evolution.
