石林彩玉的宝石矿物学特征研究

摘要

Shilin Colorful Jade with its gorgeous color,hard texture and delicate is widely concerned. By using some conventional gemmological methods,we have made a polarizing microscope observation of thin sections,including the infrared spectroscopy,X-ray fluorescence,Raman spectrum and X-ray power diffraction test. The results show that Shilin Colorful Jade belongs to fiber - shaped structure of cryptocrystalline quartz jade,containing a small amount of moganite,hematite,goethite,chlorite etc. An analysis of X fluorescence spectrometric characters concludes that the elements of Si,Cu,K,Ca,Ti,Mn and Ba were found in Shilin Colorful Jade.%石林彩玉以其绚丽多彩的颜色、质地坚硬细腻受到广泛关注.研究采用常规宝石学测试、偏光显微镜薄片观察、红外光谱、X射线荧光、拉曼光谱、X衍射仪等测试,结果表明:石林彩玉属于隐晶质—纤维状结构的石英质玉,含少量斜硅石、赤铁矿、针铁矿、绿泥石等.X荧光光谱分析得出石林彩玉中含有Si、Cu、K、Ca、Ti、Mn、Ba等元素.
