| 摘 要： | 主要对黄铁矿及石英的某些标型特征进行研究，并推测成矿的有利部位，研究发现，本区成矿阶段的黄铁矿为ｎ＋ｐ混合型，ｐ型含量愈高，矿化愈好，金品位高值区与热电系数标志值５００～７００部位吻合，主成矿阶段出现（１００）＋（３２１）＋（２１０）＋（３２１）及（１００）＋（２１０）＋（１１１）黄铁矿聚形，石英热发光强度大（大于０．５Ｒ）发光曲线峰多（双峰），总积分强度大于４．３Ｒ是本区主成矿阶段的一个标志。

| Abstract: | The paper mainly studies some typomorphic characteristics of pyrite and quartz, and presupposes the favourable place of ore-forming. The studies indicate that the pyrite in the mineralization stages is of n+p type, and the more the quantity of p type, the better the gold mineralization. The high-grade place of gold coincides with the place of mard value 500-700 of thermoelectrical coefficient.The crystal habits, such as {100}+{321},{210}+{321}and {100}+{210}+{111},are found only in the main mineralization stage. One of the marks of the main mineralization stage in this region is that the integral intensity of thermoluminescence of quartz is more than 0.5R, and there is at least a two-peak. curve of thermoluminescence. |
