| 摘 要： | 晴隆大厂锑矿是西南地区大型锑矿之一。前人已进行过深入的研究，在很多方面已达成共识，但对其成矿流体性质和来源尚有争议。本文通过对大厂锑矿流体包裹体的温度与盐度、密度与压力、包裹体成分和氢氧同位素等的研究，得出大厂锑矿成矿流体属于中低温（129．4～214c（=）、低盐度（NaCI）0．18％～3．23％、中等密度（0．93—1．03g／cm3）；流体水化学类型属F-=SO4^2- -K＋-Ca＋型。流体压力为超高压（103．97087836MPa）；成矿流体主要是大气降水形成的地下热水，可能有部分岩浆热液的掺入。

| Abstract: | Qinglong Dachang Antimony deposit is one of large typical antimony deposits in southwestern Guizhou Province, China. Predecessors have already conducted in-depth study and reached a consensus in many ways, but there were some controversies in the nature and source of the ore-forming fluid. This paper studied temperature, salinity, density, composition, pressure and oxygen-hydrogen isotope compositions of fluid inclusions in Dachang Antimony deposit. Study results indicate that the ore-forming fluid of the Qinglong Dachang Antimony deposit belongs to low-medium temperature（ 129.4 - 14 ℃ ） ,low salinity（0.18% -3.23% of NaCI） and medi- um density （0.93 - 1.03 g/cm3 ） fluid. The hydrochemical type of the fluid inclusions belongs to F- - SO42-- - K＋ -Ca＋ type. The ore-forming fluids with a super high pressure （103. 97087836 MPa） mainly originated from subsurface hydrothermal water, probably, immingled with certain parts of magmatic-hydrothermal water. |
