摘要
铝硅钡石是缅甸帕敢翡翠矿床中新近发现的一种矿物.采用显微镜下观察,并配合X射线粉晶衍射、红外吸收光谱、电子探针等测试分析方法,对铝硅钡石的矿物学特征进行了初步研究.电子探针分析表明,样品中的主成分w（BaO）为35.11%～37.88%,w（Al2O3）为27.22%～29.33%,w（SiO2）为31.20%～33.57%.依据EPMA,TG,IR测试结果推测,帕敢翡翠矿区的铝硅钡石有无水、含部分水及含标准水3种类型,H2O为结构水.
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.
