| 英文摘要 | The Sawuershan region, one of the important gold metallogenic belts of Xinjiang, is located in the western part of the Kalatongke island arc zone of north Xinjiang, NW China. There are two gold deposits in mining, namely the Kuoerzhenkuola and the Buerkesidai deposits. Gold ores at the Kuoerzhenkuola deposit occur within Carboniferous andesite and volcanic breccias in the form of gold-bearing quartz-pyrite veins and veinlet groups containing native gold, electrum, pyrite, pyrrhotite and chalcopyrite. Gold ores at the Buerkesidai deposit occur within Carboniferous tuffaceous siltstones in the form of gold-bearing quartz veinlet groups and altered rocks, with electrum, pyrite and arsenopyrite as major metallic minerals. Both gold deposits are hosted by structurally controlled faults associated with intense hydrothermal alteration. The typical alteration assemblage is sericite + chlorite + calcite + quartz, with an inner pyrite-sericite zone and an outer chlorite-calcite-epidote zone between orebodies and wall rocks. delta S-34 values (0.3-1.3 parts per thousand) of pyrite of ores from Kuoerzhenkuola deposit are similar to those (0.4-2.9 parts per thousand) of pyrite of ores from Buerkesidai deposit. delta S-34 values (1.1-2.8 parts per thousand) of pyrite from altered rocks are similar to delta S-34 values of magmatic or igneous sulfide sulfur, but higher than those from ores. Pb-206/Pb-204, Pb-207/Pb-204 and Pb-208/Pb-204 data of sulfide from ores range within 17.72-18.56, 15.34-15.61, and 37.21-38.28, respectively. These sulfur and lead isotope compositions imply that ore-forming materials might originate from multiple, mainly deep sources. He and Ar isotope study on fluid inclusions of pyrites from ores of Kuoerzhenkuola and Buerkesidai gold deposits produces Ar-40/Ar-36 and He-3/He-4 ratios in the range of 282-525 and 0.6-9.4R/Ra, respectively, indicating a mixed source of deep-seated magmatic water (mantle fluid) and shallower meteoric water. In terms of tectonic setting, the gold deposits in the Sawuershan region can be interpreted as epithermal. These formations resulted from a combination of protracted volcanic activity, hydrothermal fluid mixing, and a structural setting favoring gold deposition. Fluid mixing was possibly the key factor resulting in Au. deposition in the gold deposits in Sawuershan region. |
