Abstract: The fundamental parameters, the average chemical composition and the petrochemical models of the continental crust in North China are presented. The total mass of this crust is 1.5×10¹⁷t It is mainly composed of 13 elements, and the total weighted abundances of the silicon, aluminium and oxygen are 82.75%. The volumetrical abundance of oxygen is 94.2%. In each cubic kilometer of rocks in this crust, there are 210×10⁶t aluminium, 132×10⁶t iron, 8.7×10⁶t titanium and 2.2×10⁶t manganese. The calculation and usages of the petrochemical models shown by weighted abundance, volumetrical abundance and relative abundance respectively are also paid attention.
