平顶山金矿石英的找矿矿物学研究

Study on quartz mineralogy for ore prospecting in Ping-Ding-Shan Gold Deposit

石英是平顶山金矿重要的脉石矿物，也是金的主要载体。ＳｉＯ２含量低于９６％，而Σ（Ａｌ２Ｏ３＋Ｋ２Ｏ＋Ｎａ２Ｏ）含量高于１．０％的石英为富含金石英；富含金石英的热释发光谱以多峰为其主要特征；富含金石英的晶胞参数（ａ０、ｃ０）远大于不含金石英。因此，上述石英的标型特征可作为平顶山金矿重要的找矿标志。

Quartz is the important gansue mineral as well as main camel of gold in PingDingShan Gold Deposit. Quartz, in whiCh the SiO2 occupies less than 96% and Σ (Al2O3+K2O+Na2O)occupies more than 1. 0 %, is rich in gold. The thermoluminescence spectrum of the gold-rich quartz is characterized mainly by multi-peak. The unit cell parameters (a0, c0) of the gold-rich quartz are far greater than the bsrren one. The above typomorphic characteristics of quartz can be the principal prospecting criteria in Ping-Ding-Shan Gold Deposit.
