Abstract: The Baiyun gold deposit is one of large gold deposits in eastern Liaoning Province,with many controversies on ore-forming material source and ore genesis. This paper presents systemic researches on stable isotope geochemistry of H, O, S and C in this deposit. The δ18OV-SMOW and δDV-SMOW values of the ore-forming fluid range from 13.5‰ to 15.9‰ and from -107‰ to -83‰, respectively, which indicates that the ore-forming fluid is mainly composed of magmatic fluids. δ34SV-CDT values of pyrite grains in the ores range from -8.3‰ to 2.9‰, with enrichment of 32S and depletion of 34S, and have great difference from the sulfur isotope composition of surrounding rocks(7.0‰~18.7‰). δ13CV-PDB values of the calcite in the ores range from -2.2‰ to -0.4‰, suggesting its igneous carbonates or mantle xenoliths source and obviously different from the composition of carbon isotope of marble of Liaohe Group. The comparison of ore-forming elements in the different geological bodies shows that the source of ore-forming material has no necessary correlation with strata of the Liaohe Group. The geologic and geochemical features of the Baiyun deposit suggest that this gold deposit belongs to the magmatic hydrothermal gold deposit related to hypomagmaism.

Key words: Liaoning Province, Baiyun gold deposit, stable isotope, geochemistry, magmatic hydrothermal gold deposit, ore genesis
