摘　　要：目前市场上的和田玉产自新疆、青海、俄罗斯和韩国等地,分别称为新疆料、青海料、俄料和韩料。韩料是和田玉市场上较新出现的一个品种,目前对其研究还不够系统。通过拉曼光谱、红外光谱(FTIR)、X射线衍射(XRD)、X荧光光谱(XRF)、扫描电子显微镜(SEM)及偏光显微镜分析等测试系统地研究了韩料和青海料的矿物组成、化学成分和显微结构等方面的特征。测试分析表明两者的主要矿物组成和化学成分极为相似,且主要成分为透闪石,特征拉曼位移为667 cm-1和1051 cm-1。XRF显示Fe含量的高低与颜色的深浅呈正相关。青海料的结晶度明显好于韩料,结构也更细腻、致密,定向性也更好,结构上的差异为和田玉的评价提供了一定的理论依据。The nephrite in the market come from different deposits, like Xinjiang, Qinghai, Russia and South Korea. The nephrite from the South Korea is a new kind of jade, which hasn′t been thoroughly studied yet. The chemical components, physical structures and geological character of different nephrite samples from Qinghai and South Korea are studied by Raman spectrum, Fourier transform infrared （FTIR）, X-ray diffraction （XRD）, X-ray fluorescence （XRF）, scanning electron microscope （SEM） and polarizing microscope. The testing results show that the chemical components are similar and the main geological composition of nephrite is tremolite, the feature Raman shifts are 667 and 1051 cm-1. XRF shows that the content of Fe has a positive correlation with the color. While the crystallinity of nephrite from Qinghai is better and the fibers are better aligned than the nephrite from South Korea. The differences in physical structures offer the theoretical basis for nephrite＇s quality evaluation.
