Preliminary Study on Characteristics of Serpentine Jade from Jilin Province
-
摘要: 对产自吉林省白山市抚松县沿江乡的蛇纹石玉样品分别从地质背景、激光诱导离解光谱、X射线粉末衍射和红外吸收光谱等方面进行了研究, 并与辽宁岫玉样品进行了对比。结果表明, 吉林蛇纹石玉样品的主要颜色为深浅不一的绿色, 主要含Si, Al, Cr, Fe, Mn, Mg, Ca, Sr和Na等元素, 其中Ca与Mg的谱线较强, Al, Mn与Sr的质量分数少;X射线粉末衍射结果显示, 样品的主要矿物组成为纤蛇纹石, 红外光谱结果也显示了其具有纤蛇纹石峰值的特征。Abstract: The serpentine jade samples from Yanjiang Village in Fusong County of Baishan City, Jilin Province, are studied from the geological background, laser-induced breakdown spectroscopy (LIBS), X-ray powder diffraction as well as FTIR spectrum, and compared with the serpentine jade samples from Liaoning Province in this paper.The results show that the main colour of the serpentine jade samples from Jilin Province is various green.The samples contain the elements such as Si, Al, Cr, Fe, Mn, Mg, Ca, Sr and Na, with the stronger spectra of Ca and Mg and the low contents of Al, Mn and Sr.The results of X-ray powder diffraction show that the samples from Jilin Province mainly consist of chrysotile.The results of FTIR spectrum show the spectral characteristics of chrysotile.
