Huajian gold deposit is located in the eastern part of Hebei Province where contains abundant iron and gold resources. In this paper, the field investigations, microscopic identification and electron microprobe analysis are accomplished on the metallic minerals in Huajian gold deposit. The results suggest that pyrite and quartz are the main gold-bearing minerals in Huajian gold deposit and Au mainly exists as silver-bearing native gold. In this case, silver-bearing native gold generally occurs in the micro-fissures of pyrite or as inclusions in pyrite. The average sulfur value of pyrite is 52. 11% and it is lower than the theoretical value, indicating a magmatic hydrothermal genesis. The δD and δ18O values of the fluid vary from 77.9‰ to 68.1‰, and from 9.9‰ to 15.7‰, respectively. The δ34 S values of pyrite vary from 3. 2‰ to 6‰. They indicate that the sources of ore-forming solution are mainly magmatic fluid and sulfur is derived from deep-seated magma. We argue that the Huajian gold deposit is a magmatic hydrothermal deposit.
