摘要: 新疆首次发现了质量上佳的祖母绿宝石 (绿柱石)，受到了国内外学者的高度关注。文章对新疆祖母绿矿物晶体进行电子探针显微分析 (EPMA) 和X射线衍射 (XRD) 测试，获得EPMA成分分析结果及XRD测试晶胞参数、衍射图谱。结果表明，新疆祖母绿化学成分中Cr2O3含量较高，一般在0.21%~0.54%；典型样品晶胞参数测定结果为a0=0.9233 nm，c0=0.9206 nm，Z=2，主要粉晶谱线为2.871 (100)、3.257 (100)、7.996 (100)。

Abstract: The high grade emeralds (beryls) which were first discovered in Xinjiang have attracted attention of domestic and foreign scholars. In this paper, electron probe microanalyzer (EPMA) and X-ray diffractometer (XRD) were used for obtaining the data of chemical components, crystal cell parameters and diffraction patterns of the emeralds. The analytical results showed that the content of Cr2O3 in emeralds was higher up to 0.21% to 0.54% and the emerald cell parameters were a0=0.9233 nm, c0=0.9206 nm, Z=2 with main powder diffraction spectral lines of 2.871 (100), 3.257 (100), 7.996 (100).
