摘要黄铁矿的反射率均低于标准黄铁矿。含金黄铁矿的晶胞参数a_0为5.4170A—5.4175A、热电系数为正值。在600—200(cm~(-1))波数内,红外光谱曲线的吸收谷较为开阔,且随含金量的增加有向长波方向产生系统位移的趋势。在其求I矿,氧、氢和碳的同位素丰度是:δO_(SiO_2)~(18)11.93—16.3‰、δO_(H_2)~(12)O-1.06—4.34‰、δD—84.4—-128.8‰、δC~(13)-12.92—-17.22‰。在石英的包裹体气相中,CH_4/CO_2值为0.009—0.056,在液相中,l_7矿脉富K~+,l_(17)矿脉的K~+、Na~+相等,其它均为富Na~+型。离子组合及矿化度与岩体一致,矿化度属淡水型。文中还提出了说明矿床成因的地质年龄、化探成果、稳定同位素和流体包裹体成分的依据,补充了找矿评价的硫化物存在、黄铁矿的热电系数和红外谱标志。
The pyrite reflectivity is lower than the standard pyrite. Gold-bearing pyrite unit cell parameters a_0 5.4170A-5.4175A, the thermoelectric coefficient is positive. In the 600-200 (cm ~ (-1)) wave number, the absorption valley of the infrared spectrum curve is more broad, and with the increase of the gold content, there is a tendency of systematic displacement to the longwave direction. The abundances of isotopes of O, O, H and C are δO_ (SiO_2) ~ (18) 11.93-16.3 ‰, δO_ (H_2) ~ (12) O-1.06-4.34 ‰, δD- 128.8 ‰, δC ~ (13) -12.92--17.22 ‰. In the gas phase of quartz inclusions, the value of CH_4 / CO_2 is 0.009-0.056. In the liquid phase, the K_ + and Na_ (+) isotopes of K_ + and I_ (17) + Type. The ion combination and salinity are consistent with the rock mass, and salinity belongs to the freshwater type. In the paper, the geologic age, geochemical exploration results, stable isotopes and fluid inclusions of the genesis of the deposit are also proposed, which supplement the presence of sulphides, the pyroelectric coefficient and the infrared spectrum of pyrite.
