Kanchuangou Mo--Cu deposit is located in the southeast part of Mudanjiang --Jiamusi polymetallic metallogenic belt��and the mineralization of Cu--Mo formed in granodiorite and granite-porphyry�� The research of major elements indicated that ore forming intrusive rock has high Sr��Na��K and low Y��Mg��possessing the characteristics of calc-alkali magma evolution��and belonged to C--type adakites�� The test of trace elements showed that the local granite lacked of HFS elements as Nb and Nd��relatively enriched in lithophile element as Rb and Ba��also showed the adakitic attribute of the granite rock in this area�� The composition of rare earth elements has slight negative Eu abnormal��showing a certain degree fractional crystallization��or ever affection of the plagioclase fractional crystallization occurred in the plagioclase��and magma was the crust source��and a certain amount of garnet residual existed in the magma source�� This deposit is porphyry--hydrothermal vein in type��and its formation closely related to the subduction of the Pacific Plate��
