Zaozigou gold mine is located in the northern margin of the West Qinling orogenic belt, and its reserve has reached the super-large scale with the exploration during recent years. The geochemical characteristics of rock in mine revealed that the mine magmatic rock has the characteristics of the Himalayan granite. The paper analyzed the relation between the environment of magmatic rock and gold metallogenesis, and supposed that the source of gold was the crustal material under the thickening mechanism related to Himalayan granite. The coupled enrichment of magmatic hydrothermal solution-structures-country rock should be the main factor to develop the accumulation of gold deposit.
