    • Abstract
  • Cymrite is a new discovered mineral in the jadeite jade deposit of Myanma. The mineralogical characteristics of the cymrite are studied initially by using microscope, X-ray powder diffraction, infrared spectrum and electron microprobe. Electron microprobe analysis shows that the main compositions in the sample are w(BaO): 35.11%~37.88%,w(Al2O3): 27.22%~29.33% and w(SiO2): 31.20%~33.57%. According to the results of EPMA, TG and IR analysis, there are three kinds of the cymrite. They are of waterless, part water-bearing and standard water-bearing. H2O is structure water.
