| 英文摘要 | The fluid inclusions of sankuanggou skarn fe-cu deposit can be classified into liquid-rich two-phase, gas-rich two-phase and daughter mineral-bearing polyphase types. based on the studies on petrography, microthermometry and laser raman spectrographic analyses of fluid inclusions in the quartz phenocrysts from granodiorite and fluid inclusions in the quartz and calcite from the ores formed in sulfide and quartz-carbonate stages, respectively. the homogenization temperatures of fluid inclusions for the quartz phenocrysts average 432 degrees c, and salinities range from 30.92 wt% to 63.91 wt% nacl eqv. with average of 52.96 wt% nacl eqv. indicating that the fluid is dominated by magmatic water with high temperature and high salinity. homogenization temperatures of fluid inclusions for the chalcopyrite magnetite ores, chalcopyrite ores and quartz-carbonate veins range mainly from 323 to 424 degrees c, 333 to 441 degrees c, and 124 to 140 degrees c respectively, corresponding to salinities of 8.95 wt% similar to 62.51 wt% nacl eqv., 8.28 wt% similar to 65.32 wt% nacl eqv and 1.65 wt% similar to 4.34 wt% nacl eqv., respectively. both iron and copper ores are formed by high-temperature and high-salinity fluid, and the ore-forming fluid belongs to nacl-h(2)o-co(2)-h(2)s-ch(4) system, which is characterized by high na, k, ca, cl(-) and co(3)(2-) components. in late stage, the ore-forming fluid evolved to the low-temperature and low-salinity aqueous solution because of the mixture of meteoric water. the boiling event of ore-forming fluid occurred in sulfide stage with temperature of 300 similar to 400 degrees c triggered by tectonic decompression processes, resulting in formation of massive metal sulfides and magnetite. the fluid boiling was favorable for formation of the sankuanggou skarn fe-cu deposit. |
