The Jinchang gold deposit related to the Gezhen shear zone is located in the North-East part of the Gezhen auriferous shear zone in western Hainan province,China. There are five important gold deposits: Jinchang, Baoban, Beiniu, Erjia and Bumo gold deposits along the Gezhen shear zone from NE to SW direction. They are located in the conjoint site of Eurasian plate, Pacific plate and India ocean plate in the tectonic. The Jinchang gold deposit belongs to fragmentary altered rock gold deposit. The ore bodies occur mainly in migmatite in the hanging wall of shear zone. In this paper, we choose the Jinchang gold deposit as the study object. Through systematical study in geological characteristics, fluid inclusion geochemistry and geochronology, and compare it with the other gold quartz vein in the Gezhen Au metallogenic area, we discussed the character and genesis of ore-forming fluid and mineralization and precipitation process of the Jinchang gold deposit.
