摘要
对石英的热发光和红外光谱特征研究表明:在石英脉型和蚀变岩型金矿床中,成矿期石英的热发光强度大,在水和二氧化碳的波长范围内,红外光谱吸收强度大,光密度值大,与不含金脉石英有较大的差別。因此,研究石英的这两种特性,对找金和研究金矿的富集规律有一定的意义。
Studies on the thermoluminescence and infrared spectrum of quartz indicate that in the quartz vein type and altered rock type gold deposits, the quartz related to mineralization has intensive thermoluminosity and strong absorption in infrared spectrum in the wavelength of water and carbon dioxide and higher light density value, which greatly differs from those quartz in gold-barren veins. Therefore, it is of significance to study the two properties of quartz in the exploration for gold and investigation of gold enrichment.
