英文摘要The Dasuji Mo deposit lies on the northern margin of the North China Craton. Based on vein crosscutting relationships, mineral assemblages, and alteration characteristics, the formation of the deposit can be divided into four stages: K-feldspathization with minor Mo mineralization (stage 1), the main stage of Mo mineralization (stage 2), Pb-Zn mineralization (stage 3), and post-mineralization (stage 4). This paper presents new He-Ar-S isotopic data to constrain the origin of this deposit. Pyrite-hosted fluid inclusions yield He-3/He-4 ratios of 0.21-3.48 Ra (average = 0.96 Ra; Ra = 1.4 x 10(-6)) and Ar-40/Ar-36 ratios of 464.9-832.1 (average = 624.6), which indicate the ore-forming fluids were predominantly crust-derived with minor mantle-derived components. Molybdenite within the deposit contains 0.06-29 ppm Re, indicative of derivation from a crustal source. delta S-34 values of sulfide samples range from + 3.14 to + 6.84 parts per thousand, with corresponding H2S delta S-34 values of stage 2 fluids of + 2.8 parts per thousand to + 3.1 parts per thousand and stage 3 fluids of + 4.9 parts per thousand to + 5.9 parts per thousand. The delta S-34(fluid) values of stages 2 and 3 are + 3.1 parts per thousand to + 4.0 parts per thousand and around + 6 parts per thousand, respectively. The escape of H2S during stage 2 was a key factor in increasing delta S-34(fluid) values, and contributed to the precipitation of sulfides.
