摘要
利用电子探针(PXRF)、X射线粉末衍射(XRD)及红外光谱(FIR)等技术手段对危地马拉翡翠样品进行分析,并与缅甸翡翠的宝石矿物学特征进行对比研究。结果表明,危地马拉翡翠的化学成分与硬玉的基本相同。矿物组成主要为硬玉,并且含有钠长石、白云母以及少量金云母、黝帘石、榍石和方沸石等。结构主要为柱粒状变晶结构与碎裂结构,是导致其质地较粗的主要原因之一。红外光谱与缅甸翡翠的红外光谱相比有明显漂移。
The samples of Guatemala jadeite were analyzed by electron probe analysis （EP）, X-ray powder diffraction （XRD） and infrared spectroscopy OR）, and compared with the gem mineralogical characteristics of the Burma jade. Which shows that the chemical compositions of jadeite are as same as the jade＇s in Guatemala. The main minerals in Guatemala jadeite are jade containing albite, muscovite, and few phlogopite, zoisite, titanite and analcime; the main structures are columnargrain metacryst structure and cataclastie texture structure, which is one of the mainly reasons why their texture are crude; the infrared spectroscopy of Guatemala jade is drifted obviously than the Burma jade＇s.
