摘　　要：张家坪子金矿位于四川冕宁境内,通过对该矿床石英中的包裹体测温可知,温度主要集中在200-300℃,流体的盐度变化在6.37-16.12wt%Na Cl,主要集中在4-10wt%Na Cl。C、O同位素表明张家坪子金矿床中水可能为变质水,成矿物质为多处来源,很可能来自地幔。Zhang Jia Ping Zi gold deposit locates in Mianning, Sichuan Province, temperature measurement of inclu-sions in the quartz ofthe deposit shows that, the temperature is mainly concentrated between 200-300 ℃, the fluid sa-linity changes at 6.37- 16.12wt%Na Cl, mainly concentrated in the 4 - 10wt%Na Cl. C and O isotopes indicate thatthe water of Zhang Jia Ping Zi gold deposit may be metamorphic waterand ore-forming materials have multiple sourc-es, most probably derived from the mantle.
