通过对金窝子石英脉型金矿床中黄铁矿的形成世代、晶体形态及热电性进行研究,结果表明:黄铁矿的形成可划分为4个世代,其中第二和第三世代黄铁矿含量高、含金性较好;黄铁矿晶形较为简单,仅出现立方体、五角十二面体及它们组合成的聚形,矿脉由上至下,晶形的变化趋势预示矿脉向深部仍有一定的延伸;黄铁矿热电系数的测定表明本区金矿床的形成温度为中低温;各矿脉的黄铁矿热导电型多以空穴型(P型)为主、热电系数(α)和热电性参数(Xnp)变化不大、剥蚀率(γ)低,显示矿区含金矿脉规模较大、剥蚀程度较低,深部具有较好的找矿前景。
The formation of pyrite in the Jinwozi quartz vein type gold deposit, crystal morphology and thermoelectric properties were studied. The results show that the formation of pyrite can be divided into four generations, in which the second and third generation of yellow iron The ore content is high and the gold content is good. The pyrite crystal form is relatively simple, only the cubes, pentagonal dodecahedron and their combination are formed. The veins from top to bottom, the trend of crystal form indicates that the veins still have a certain depth The thermoelectric coefficient of pyrite shows that the formation temperature of the gold deposit in this area is low and middle temperature. The thermal conductivity of pyrite in each vein is mainly of hole type (P type), and the pyroelectric coefficient (α) and thermoelectric The Xnp shows little change and the erosion rate (γ) is low, which shows that the ore-bearing gold veins are large in scale and low in denudation, and have good prospecting prospect in the deep part.
