摘　　要：选取绿色的缅甸翡翠和危地马拉翡翠为研究对象,采用常规宝石学测试以及红外光谱仪、紫外-可见光谱仪和显微拉曼光谱仪进行谱学特征和矿物成分分析。实验结果表明:绿色缅甸翡翠的主要组成矿物为硬玉,含有次生矿物绿辉石、方解石,绿色危地马拉翡翠的主要组成矿物为绿辉石或者绿辉石-硬玉,含有次生矿物硬玉和碳。3D显微拉曼扫描结果显示危地马拉翡翠中存在明显的绿辉石与硬玉交织共生,同时证明3D显微拉曼扫描是一种有效的研究翡翠矿物组成的无损测试手段。In this study,seventeen green jadeite samples from Myanmar and twenty green jadeite samples from Guatemala were tested by various methods and techniques,including standard gemmological tests,infrared spectrometer,UV-visible spectrometer,and micro-Raman spectrometer,aiming to analyze the spectral characteristics and mineral components.The experimental results show that the main mineral component of green jadeite from Myanmar is jadeite,containing secondary minerals omphacite and calcite,while the main mineral components of green jadeite from Guatemala are omphacite or omphacite-jadeite,containing secondary minerals jadeite and carbon.The results of 3D micro-Raman mapping show that there is obvious interweaving and symbiosis between omphacite and jadeite in Guatemalan jadeite,which proves that 3D micro-Raman mapping is an effective nondestructive testing method to study the mineral composition of jadeite.
