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)。 Xinjiang first discovered a good quality emerald gemstones (beryl stone), has been highly concerned by scholars at home and abroad. In this paper, EPMA and XRD were performed on the emerald green mineral crystals of Xinjiang to obtain EPMA composition analysis results and XRD test unit cell parameters and diffraction patterns. The results show that the content of Cr2O3 in the chemical composition of Xinjiang emerald is relatively high, generally ranging from 0.21% to 0.54%. The typical unit cell parameters are a0 = 0.923 3 nm, c0 = 0.920 6 nm, Z = 2, The lines are 2.871 (100), 3.257 (100), 7.996 (100).
