Abstract The gold deposits in the Xifengkou-Daoerdeng metallogenic belt occur in different rocks such as granite, metamorphic rocks and sedimentary rocks. The orebodies are distributed in fault zones and related with hydrothermal fluids. Based on the Pb-S-O-H isotopic data, the gold deposits were formed consistently with Yanshanian granite. The hydrothermal fluids were derived from the granite. Thus the sulfur in pyrite was sourced from the granite. In summary, the gold deposits are post-granite hydrothermal deposits. The granite extracted ore-forming materials from some Archean metamorphic rocks during intrusion, then transported them to shallow level of the crust and deposited in the structural fractures.
