| 摘 要： | 本文对海南二甲金矿不同含金性的石英进行了粉末红外光谱的研究。结果表明,OH 基团(H_2O)及 CH 分子(CH_4)谱带的强度与石英的 Au 含量和 Al 含量呈明显的正相关;Si—O—Si 的对称伸缩振动强度及 Si—O 和 Si—Si 的变形振动强度与石英的 Au 含量,尤其是 Al 含量,总体上呈负相关;2000cm~(-1)以下各谱带的位置随石英 Au 矿化的增强表现出从高频向低频偏移的趋势。对上述结果,作者从理论上作出了较合理的分析。

| Abstract: | In this paper,the authors deai with the infrared spectroscopy of quartz powder from Erjia gold deposit.The results indicate that the vibration intensities of OH(H_2O)and CH(CH_4)are positively correlative with the quantities of gold and aluminium in quartz,the symmetrical expansion and contraction vibration intensities of Si-O- Si bond and the deformation vibration intensities of Si-O bond and Si-Si bond are negatively correlative with the Quantities of gold (especially with the quantities of aluminium)in quartz,and the position(i.e.vibration frequency)of the spectrum bands less than 2000cm drift from high frequency to low frequency with the strengthe- ning of gold mineralization in quartz.Theoretical studies of the results of infrared spectroscopy are also made by the authors. |
