| 摘 要： | 尽管角闪石在地壳中大量存在 ,但是蓝色钾 钠透闪石却是角闪石中的稀有品种。本文采用X射粉晶线衍射和晶胞参数计算 ,确定该矿物为蓝色的钾 钠透闪石 ,用电子探针 (EMPA)精确分析了它的化学成分 ,确定为钾 钠透闪石 ,而不是蓝色软玉 (即不是透闪石或阳起石 )。

| Abstract: | Although amphiboles are widespread in the Earth's crust, K Na richterite is generally considered to be one of the rare species. In this research, X ray powder diffraction was used (table 1) to determine the unit cell parameters of the samples (table 2).Besides, chemical composition was analysed by electron microprobe analyses (EMPB) to determine the chemical formula. The analyses show that the sample blue "nephrite" is richterite, but not tremolite or actinolite. |
