八卦庙金矿的石英可分为 3期 ,即早期近EW向顺层脉、中期NE向节理脉和晚期缓倾斜切脉。X光衍射分析表明 ,石英的晶胞参数、晶胞体积及有关衍射强度比值 (I10 1/I10 0 )和石英的Au含量相关关系不明显 ,但总体上有关晶胞参数值较一般标准石英的要大 ;不同标高石英的晶胞参数表现为脉动式的变化。另外 ,从成矿早期到晚期 ,c0 /a0 和I10 1/I10 0 值随温度降低而有所降低。石英薄片红外光谱研究结果表明 ,石英包裹体中H2 O的相对光密度D1/D0 值除一个样品较小 (0 32 )外 ,其余均在 1 2 3~ 4 77,平均 2 3143。总体上Au含量较高的石英其H2 O和CO2 的相对光密度D1/D0 和D2 /D0 值也具相对较高的趋势 ;并且D1/D0 和D2 /D0 具有密切的正相关关系 ,相关系数为 0 858,这种同步增长说明H2 O和CO2 气液丰富有利于Au的矿化富集。标高相差 150m样品的H2 O和CO2 的相对光密度值未发生显著变化且均显示含Au性较好的信息 ,说明八卦庙金矿深部的矿化前景依然不错
Quartz Temple Gold Mine quartz can be divided into three, namely, the early EW synclinal vein near the mid-term to the articular synopsis and late gently inclined incision. X-ray diffraction analysis showed that the correlation between unit cell parameters, unit cell volume and related diffraction intensity ratio (I10 1 / I10 0) and quartz Au content is not obvious, but the overall unit cell parameters are generally lower than that of standard quartz To be large; different elevation quartz unit cell parameters showed pulsatile changes. In addition, the values of c0 / a0 and I10 1 / I10 0 decreased from the early to the late stage of metallogenesis as the temperature decreased. The infrared spectra of quartz thin films show that the relative optical density D1 / D0 values of H2 O in quartz inclusions are all 1231 to 433, except one sample is smaller (0 32). In general, quartz with higher Au content has a relatively higher relative optical density D1 / D0 and D2 / D0 values for H2 O and CO2; and D1 / D0 and D2 / D0 have a close positive correlation, and the correlation coefficient Is 0 858, indicating that the simultaneous growth of H2 O and CO2 gas-liquid enrichment is conducive to the mineralization of Au enrichment. The relative optical density values of H 2 O and CO 2 did not change significantly with 150m elevation difference and all showed good Au information, indicating that the mineralization prospect in the deep part of Baguamiao gold mine is still good
