我们这次工作,收集了6个白云岩型的矿区,共26个纤蛇纹石石棉样,经手选,并在双目镜下挑选了纯净丝状光泽的纤维,分别做了化学全分析、X光粉晶照相和衍射、电子显微镜及电子衍射、红外吸收光谱、差热和热失重等方面的研究.在国内第一次发现吉林集安的纤蛇纹石绝大部分为正纤蛇纹石(在一些样中含有极少量的副纤蛇纹石).首次提出它的红外谱图, Our work collected 6 dolomite-type mines, a total of 26 chrysotile asbestos-like samples, hand-selected, and under the binocular selected pure filamentous luster of the fibers, respectively, to do a full chemical analysis, X-ray crystallography and diffraction, electron microscopy and electron diffraction, infrared absorption spectroscopy, differential thermal and thermogravimetric studies etc. For the first time in China, most of the chrysotile in Jilin Ji’an are orthometric serpentine Stone (in some cases contains a very small amount of Vice Chrysotile.) For the first time its infrared spectrum,
