The Jincheng gold deposit, in the Luoshan County, Henan Province, lies in south of Tongbai Shangcheng ductile shear zone. Based on the geologic feature, the authors conducted the comparative study on REE and trace element characteristics of granite-porphyry dyke and Lingshan granitic mass. Then, the authors further investigated the oxygen isotope compositions of the paragenous quartz and the carbon isotope compositions of fluid inclusions within paragenous quartz, as well as the sulfur and lead isotope compositions of the paragenous pyrite. The authors found that the REE and trace element characteristics of granite-porphyry dyke are similar to those of the Lingshan granitic mass, and that the granite-porphyry dyke originated in the magmatic hydrothermal activities in the late Yanshanian stage. According to our research, we consider that the ore-forming materials are mainly derived from the Huwan formation complex, and secondly derived from the magmatic hydrothermal activities in the late Yanshanian stage.
