摘要
本文对翡翠中主要组成矿物绿辉石的矿物学特征进行了探讨。研究表明绿辉石的主要化学成份为ＳｉＯ２、Ａｌ２Ｏ３、Ｎａ２Ｏ，含有少量ＴＦｅＯ、ＭｇＯ、ＣａＯ、Ｃｒ２Ｏ３、ＭｎＯ、ＴｉＯ２、Ｋ２Ｏ。其绿辉石的化学成份介于硬玉与透辉石的二元混溶系列的中间态，具有Ｐ２或Ｐ２／ｎ型结构绿辉石的特征，这也得到了绿辉石的Ｘ射线粉晶衍射分析的证实。
The mineralogical features of omphacite in jadeite jade were discussed in the paper.The study shows that main chemical compositions of omphacite, locating between jadeite and diopside, are SiO 2,Al 2O 3 and Na 2O with minor TFeO,MgO,CaO,Cr 2O 3,MnO,TiO 2,K 2O,showing.the features of P2or P2/m omphacite.The X-ray diffraction analysis supported the above results.
