Discovery of Cymrite in Jadeite Jade Deposit of Myanma

WANG Xiao-li,YUAN Xin-qiang (Gemmological Institute, China University of Geosciences, Wuhan 430074, China)  
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(Al_ 2 O_ 3 ): 27.22%~29.33% and w(SiO_ 2 ): 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. H_ 2 O is structure water.
