| 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=0.923 3 nm,c0=0.920 6 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 Cr_2O_3 in emeralds was higher up to 0.21% to 0.54% and the emerald cell parameters were a_0=0.9233 nm, c_0=0.9206 nm, Z=2 with main powder diffraction spectral lines of 2.871(100), 3.257(100), 7.996(100). |
