摘要The Lesser Xing'an Range-Zhangguangcai Range metallogenic belt, located at the eastern segment of the Centra Asian metallogenic domain, hosts two giant Mo porphyry deposits, the Early Jurassic Luming deposit and the Middle Jurassic Daheishan deposit. In this study, the He-Ar and S isotopic compositions of sulfides from differen, hydrothermal stages of the Daheishan and Luming deposits were determined. Fluid inclusions hosted in pyrite: shown that He-3/He-4 ratios of the Luming and Daheishan deposit range from 0.02 to 0.32 Ra, and 0.7 to 2.5 Ra respectively. Ar-40/Ar-36 ratios of the Luming and Daheishan deposit range from 313.3 to 535.1, and 309.9 tc 360.6, respectively. He and Ar isotopic compositions suggest that the ore-forming fluids of the turning deposi are mainly crustal-derived fluids, with near atmospheric Ar and crustal He values. Mantle-derived fluids are z minor component. In contrast, the ore-forming fluids of the Daheishan deposit are a mixture between a crust derived fluid and a mantle-derived fluid. The 834S values of the sulfide samples from the Luming deposi (4.98-7.14%o) and the Daheishan deposit (1.83-2.88960) indicate that the sulfur in the ore-forming fluids wa: primarily derived from granitic magma. The isotopic compositions across the stages within one deposit have nc variability. The similar He-Ar and S isotopic compositions of the sulfides from the different Mo-bearing by drothermal stages of these two giant Mo deposits indicate that the overprinting of the multiple stages of Mo bearing hydrothermal fluids may be a key factor in the formation of giant porphyry Mo deposits. Meanwhile, the westward subduction of the Paleo-Pacific plate might have played an important role for the formation of the giant Mo deposits in the Lesser Xing'an Range-Zhangguangcai Range metallogenic belt.
